Group A (warmup) renamed to *WarmupIT. Adds Group B (list operations served from cache) — 4 scenarios: agent initialize, tools/list, resources/list, prompts/list. Each scenario carries paired client.rpt (agent at app0) and server.rpt (cache facade) so CacheListIT can verify the agent↔cache contract peer-to-peer. McpCacheListIT pairs the agent client.rpt with the Group A warmup server.rpt at app1 so the cache is populated before the agent's list arrives. B5 (list-before-warmup) stays @Ignored with a script TODO. Verified locally: CacheWarmupIT 6/6 + CacheListIT 4/4 green peer-to-peer. https://claude.ai/code/session_01WNsipAt3RGwQoeFYVxwfL8 --- .../mcp/internal/stream/McpCacheIT.java | 356 ------------------ .../mcp/internal/stream/McpCacheListIT.java | 109 ++++++ .../mcp/internal/stream/McpCacheWarmupIT.java | 108 ++++++ .../client.rpt | 34 ++ .../server.rpt | 43 +++ .../client.rpt | 62 +++ .../server.rpt | 68 ++++ .../client.rpt | 64 ++++ .../server.rpt | 70 ++++ .../client.rpt | 83 ++++ .../server.rpt | 90 +++++ .../mcp/streams/cache/CacheListIT.java | 74 ++++ .../{CacheIT.java => CacheWarmupIT.java} | 2 +- 13 files changed, 806 insertions(+), 357 deletions(-) delete mode 100644 runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpCacheIT.java create mode 100644 runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpCacheListIT.java create mode 100644 runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpCacheWarmupIT.java create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.agent.initialize.from.cache/client.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.agent.initialize.from.cache/server.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.agent.prompts.list.from.cache/client.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.agent.prompts.list.from.cache/server.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.agent.resources.list.from.cache/client.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.agent.resources.list.from.cache/server.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.agent.tools.list.from.cache/client.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.agent.tools.list.from.cache/server.rpt create mode 100644 specs/binding-mcp.spec/src/test/java/io/aklivity/zilla/specs/binding/mcp/streams/cache/CacheListIT.java rename specs/binding-mcp.spec/src/test/java/io/aklivity/zilla/specs/binding/mcp/streams/cache/{CacheIT.java => CacheWarmupIT.java} (99%) diff --git a/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpCacheIT.java b/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpCacheIT.java deleted file mode 100644 index 267008b0ed..0000000000 --- a/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpCacheIT.java +++ /dev/null @@ -1,356 +0,0 @@ -/* - * Copyright 2021-2024 Aklivity Inc - * - * Licensed under the Aklivity Community License (the "License"); you may not use - * this file except in compliance with the License.

The only cache-specific concern in the original Group D was resilience to a downstream error during warmup, which is more naturally a Group A (warmup) scenario than a fanout one. Adds cache.warmup.session.downstream.error: downstream ABORTs the tools/list stream during warmup; the lifecycle session must survive so the cache can continue with other list types or retry later.

Since all original two-binding topologies have an exact equivalent in the folded model, no expressiveness is lost and the engine "kind: cache" prerequisite goes away. Also: - Renames "warmup" → "hydrate" throughout (more precise terminology for cache population). - Flattens the warmup wrapper: authorization/store/ttl now live directly under options.cache instead of options.cache.warmup. - Drops the guarded vs. unguarded test split — the .rpt scripts don't observe authorization on BEGIN so the scenarios produce identical transcripts. - Renames IT classes: CacheXIT → ProxyCacheXIT and McpCacheXIT → McpProxyCacheXIT to align with the existing McpProxyIT neighbour. - Configs rewritten: cache.yaml/cache.multi.yaml/cache.refresh.yaml → proxy.cache.yaml/proxy.cache.multi.yaml/proxy.cache.refresh.yaml; each declares kind: proxy with options.cache and a stores: memory0 reference. - Schema patch: drop "cache" from kind enum; replace flat options.warmup/options.ttl with options.cache {store, ttl, authorization}; store is required. Verified: 10/10 ProxyCache*IT peer-to-peer tests pass. https://claude.ai/code/session_01WNsipAt3RGwQoeFYVxwfL8 --- ...eIT.java => McpProxyCacheLifecycleIT.java} | 34 ++++------ ...T.java =>

charset=UTF-8 Content-Transfer-Encoding: 8bit Renames scenarios and test methods to use "hydrate" / "serve" as verbs rather than as noun-modifiers. Examples: cache.hydrate.session.tools.list → cache.hydrate.tools cache.agent.tools.list.from.cache → cache.serve.tools.list shouldPopulateToolsViaHydrate → shouldHydrateTools shouldServeAgentToolsListFromCache → shouldServeToolsList shouldKeepHydrateSessionOpenAfter... → shouldHydratePersist Verified: 10/10 ProxyCache*IT peer-to-peer tests pass.

a3a6bf6a8a8f4f5a49a3bf673ece4378ade0bd85 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 16 May 2026 03:13:48 +0000 Subject: [PATCH 08/83] test(binding-mcp): add cache refresh scenarios + tests (#1737) Adds per-method refresh scenarios that model the cache re-issuing a list call on the same hydrate session after a TTL elapses, plus a refresh-error case where the refresh attempt aborts and the cache must retain its prior cached entry. Scenarios: cache.refresh.tools / cache.refresh.resources / cache.refresh.prompts cache.refresh.tools.error Tests: ProxyCacheToolsListIT.shouldRefreshTools ProxyCacheToolsListIT.shouldRefreshToolsError ProxyCacheResourcesListIT.shouldRefreshResources ProxyCachePromptsListIT.shouldRefreshPrompts (engine-driven counterparts added too) Also renames cache.hydrate.downstream.error -> cache.hydrate.error (and shouldHydrateDownstreamError -> shouldHydrateError) for the single-qualifier convention. Lease-contention coverage (cache.refresh.tools.contended) is deferred: the lease behavior is store-level, only meaningfully testable engine-driven via either a TestStore seeding hook or a multi-worker EngineRule. Both are downstream work from the cache binding implementation; the wire-level refresh tests above cover the protocol shape. Verified: 14/14 ProxyCache*IT peer-to-peer tests pass. https://claude.ai/code/session_01WNsipAt3RGwQoeFYVxwfL8 --- .../stream/McpProxyCacheLifecycleIT.java | 4 +- .../stream/McpProxyCachePromptsListIT.java | 10 +++ .../stream/McpProxyCacheResourcesListIT.java | 10 +++ .../stream/McpProxyCacheToolsListIT.java | 20 +++++ .../client.rpt | 0 .../server.rpt | 0 .../cache.refresh.prompts/client.rpt | 76 ++++++++++++++++++ .../cache.refresh.prompts/server.rpt | 79 +++++++++++++++++++ .../cache.refresh.resources/client.rpt | 76 ++++++++++++++++++ .../cache.refresh.resources/server.rpt | 79 +++++++++++++++++++ .../cache.refresh.tools.error/client.rpt | 79 +++++++++++++++++++ .../cache.refresh.tools.error/server.rpt | 76 ++++++++++++++++++ .../cache.refresh.tools/client.rpt | 76 ++++++++++++++++++ .../cache.refresh.tools/server.rpt | 79 +++++++++++++++++++ .../streams/cache/ProxyCacheLifecycleIT.java | 6 +- .../cache/ProxyCachePromptsListIT.java | 9 +++ .../cache/ProxyCacheResourcesListIT.java | 9 +++ .../streams/cache/ProxyCacheToolsListIT.java | 18 +++++ 18 files changed, 701 insertions(+), 5 deletions(-) rename specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/{cache.hydrate.downstream.error => cache.hydrate.error}/client.rpt (100%) rename specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/{cache.hydrate.downstream.error => cache.hydrate.error}/server.rpt (100%) create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.refresh.prompts/client.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.refresh.prompts/server.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.refresh.resources/client.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.refresh.resources/server.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.refresh.tools.error/client.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.refresh.tools.error/server.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.refresh.tools/client.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.refresh.tools/server.rpt diff --git a/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCacheLifecycleIT.java b/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCacheLifecycleIT.java index 680bfef262..e5423507c4 100644 --- a/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCacheLifecycleIT.java +++ b/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCacheLifecycleIT.java @@ -69,9 +69,9 @@ public void shouldHydratePersist() throws Exception @Test @Configuration("proxy.cache.yaml") @Specification({ - "${app}/cache.hydrate.downstream.error/server" }) + "${app}/cache.hydrate.error/server" }) @ScriptProperty("serverAddress \"zilla://streams/app1\"") - public void shouldHydrateDownstreamError() throws Exception + public void shouldHydrateError() throws Exception { k3po.finish();

The cache facade holds the request read in full, then waits for a per-method hydrate barrier to fire before writing the cached response. True timing isn't observable peer-to-peer, but the scripts document the required wire ordering for engine-driven tests to enforce. Scenarios + tests: cache.serve.tools.list.hydrating shouldServeToolsListHydrating cache.serve.resources.list.hydrating shouldServeResourcesListHydrating cache.serve.prompts.list.hydrating shouldServePromptsListHydrating Verified: 17/17 ProxyCache*IT peer-to-peer tests pass. https://claude.ai/code/session_01WNsipAt3RGwQoeFYVxwfL8 --- .../stream/McpProxyCachePromptsListIT.java | 11 +++ .../stream/McpProxyCacheResourcesListIT.java | 11 +++ .../stream/McpProxyCacheToolsListIT.java | 11 +++ .../client.rpt | 57 ++++++++++++++++ .../server.rpt | 62 +++++++++++++++++ .../client.rpt | 57 ++++++++++++++++ .../server.rpt | 62 +++++++++++++++++ .../client.rpt | 59 ++++++++++++++++ .../server.rpt | 67 +++++++++++++++++++ .../cache/ProxyCachePromptsListIT.java | 9 +++ .../cache/ProxyCacheResourcesListIT.java | 9 +++ .../streams/cache/ProxyCacheToolsListIT.java | 9 +++ 12 files changed, 424 insertions(+) create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.serve.prompts.list.hydrating/client.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.serve.prompts.list.hydrating/server.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.serve.resources.list.hydrating/client.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.serve.resources.list.hydrating/server.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.serve.tools.list.hydrating/client.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.serve.tools.list.hydrating/server.rpt diff --git a/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCachePromptsListIT.java b/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCachePromptsListIT.java index 1b55c7437e..783c2f71af 100644 --- a/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCachePromptsListIT.java +++ b/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCachePromptsListIT.java @@ -76,4 +76,15 @@ public void shouldRefreshPrompts() throws Exception { k3po.finish();

Second worker's lifecycle is observed but its tools/list never hits the wire because the lease was lost. - McpProxyCacheContentionIT — new engine-driven IT class configured with ENGINE_WORKERS=2 so both cache binding instances genuinely race for the hydrate / refresh leases against the shared store-memory. @Ignore'd until cache binding implementation lands. - ProxyCacheToolsListIT.shouldRefreshToolsContended — peer-to-peer counterpart added to the existing list IT. - proxy.cache.contended.yaml dropped — no longer needed (the test uses proxy.cache.refresh.yaml which already references store-memory). Verified: 18/18 ProxyCache*IT peer-to-peer tests pass (was 17, added shouldRefreshToolsContended). https://claude.ai/code/session_01WNsipAt3RGwQoeFYVxwfL8 --- .../stream/McpProxyCacheContentionIT.java | 68 +++++++++++ .../stream/McpProxyCacheToolsListIT.java | 18 --- .../mcp/config/proxy.cache.contended.yaml | 36 ------ .../cache.refresh.tools.contended/client.rpt | 110 ++++++++++++++++++ .../cache.refresh.tools.contended/server.rpt | 108 +++++++++++++++++ .../streams/cache/ProxyCacheToolsListIT.java | 9 ++ 6 files changed, 295 insertions(+), 54 deletions(-) create mode 100644 runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCacheContentionIT.java delete mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/config/proxy.cache.contended.yaml create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.refresh.tools.contended/client.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.refresh.tools.contended/server.rpt diff --git a/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCacheContentionIT.java b/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCacheContentionIT.java new file mode 100644 index 0000000000..9c3619b982 --- /dev/null +++ b/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCacheContentionIT.java @@ -0,0 +1,68 @@ +/* + * Copyright 2021-2024 Aklivity Inc + * + * Licensed under the Aklivity Community License (the "License"); you may not use + * this file except in compliance with the License.

No runtime behavior yet — McpProxyFactory still ignores the parsed config. - McpCacheConfig: immutable POJO with store, per-method ttl, authorization map (guard-name → credentials) - McpCacheConfigBuilder: fluent builder mirroring the existing McpAuthorizationConfigBuilder pattern - McpOptionsConfig: add cache field + 4-arg constructor - McpOptionsConfigBuilder: add cache() method (nested-builder pattern matching authorization()) - McpOptionsConfigAdapter: serialize/deserialize the cache block with ttl + per-guard authorization credentials Verified: binding-mcp tests pass, checkstyle clean, binding-mcp.spec SchemaTest still green. https://claude.ai/code/session_01WNsipAt3RGwQoeFYVxwfL8 --- .../binding/mcp/config/McpCacheConfig.java | 55 +++++++++++ .../mcp/config/McpCacheConfigBuilder.java | 92 ++++++++++++++++++ .../binding/mcp/config/McpOptionsConfig.java | 5 +- .../mcp/config/McpOptionsConfigBuilder.java | 15 ++- .../config/McpOptionsConfigAdapter.java | 94 +++++++++++++++++++ 5 files changed, 259 insertions(+), 2 deletions(-) create mode 100644 runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/config/McpCacheConfig.java create mode 100644 runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/config/McpCacheConfigBuilder.java diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/config/McpCacheConfig.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/config/McpCacheConfig.java new file mode 100644 index 0000000000..5e217d6048 --- /dev/null +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/config/McpCacheConfig.java @@ -0,0 +1,55 @@ +/* + * Copyright 2021-2024 Aklivity Inc + * + * Licensed under the Aklivity Community License (the "License"); you may not use + * this file except in compliance with the License.

When options.cache is present, attach() now: - resolves the unconditional exit route - allocates a HydrateSession (initialId/replyId etc.) - schedules a signaler tick that fires immediately - the tick handler issues a lifecycle BEGIN downstream with sessionId="hydrate-1", modelled after KafkaGrpcRemoteServerFactory The session sends reply WINDOW on receipt of the downstream's BEGIN reply, and END on detach. No list-method enumeration yet; tools/ resources/prompts hydrate, store integration, lease coordination, and refresh land in later phases. McpProxyCacheLifecycleIT remains @Ignore'd until all four scenarios in the class pass; verified locally that the shouldHydrate scenario itself now runs to green when temporarily un-Ignored.

charset=UTF-8 Content-Transfer-Encoding: 8bit Phase D — resolve the configured store at attach() time via context.supplyStore(resolveId.applyAsLong(cache.store)), thread the handle through HydrateSession into each HydrateListStream, and on each list reply END write the accumulated body to the store under the per-method key ("tools" / "resources" / "prompts") with no expiry (Long.MAX_VALUE). Response bodies are buffered byte-by-byte into a per-list-stream byte[] that grows as needed. On END the accumulated bytes are decoded as UTF-8 and pushed to the StoreHandler via put(). No serve-from-cache yet — agent list requests still pass through to the existing proxy code path. Phase E will intercept them and respond from the store. Verified: ./mvnw -pl runtime/binding-mcp clean verify → 149 pass, 4 list/contention ITs still @Ignore'd. https://claude.ai/code/session_01WNsipAt3RGwQoeFYVxwfL8 --- .../mcp/internal/stream/McpProxyFactory.java | 63 +++++++++++++++++-- 1 file changed, 58 insertions(+), 5 deletions(-) diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyFactory.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyFactory.java index dbd02dd894..0808b8a7cd 100644 --- a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyFactory.java +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyFactory.java @@ -29,6 +29,7 @@ import java.util.Deque;

hydrate kinds in parallel (#1737) Move the per-kind store-key plumbing out of HydrateSession into a new McpListCache attached to McpBindingConfig, dropping the redundant cacheStores map. HydrateSession becomes a populator only; the cache (backed by StoreHandler) is the source of truth for "is kind X ready?" via an async get. With per-kind status independent of session sequencing, the three list-stream round-trips dispatch on the same worker tick - wall-clock hydration drops to a single round-trip, and an error on one kind no longer delays the others or blocks a retry on reconnect. https://claude.ai/code/session_01WNsipAt3RGwQoeFYVxwfL8 --- .../mcp/internal/config/McpBindingConfig.java | 1 + .../mcp/internal/config/McpListCache.java | 67 +++++++++++ .../mcp/internal/stream/McpProxyFactory.java | 105 +++++------------- 3 files changed, 98 insertions(+), 75 deletions(-) create mode 100644 runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpListCache.java diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java index f43e4b127b..f38820e4d8 100644 --- a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java @@ -36,6 +36,7 @@ public final class McpBindingConfig public final long id; public final McpOptionsConfig options; public final GuardHandler guard; + public McpListCache cache; private final List routes; diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpListCache.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpListCache.java new file mode 100644 index 0000000000..a4a17d2b65 --- /dev/null +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpListCache.java @@ -0,0 +1,67 @@ +/* + * Copyright 2021-2024 Aklivity Inc + * + * Licensed under the Aklivity Community License (the "License"); you may not use + * this file except in compliance with the License.

construction is via `McpOptionsConfig.builder()`. - Replace the hardcoded `"hydrate-1"` constant in `McpProxyFactory` with a `Supplier` obtained from `McpConfiguration.sessionIdSupplier()`. Cache ITs configure `MCP_SESSION_ID_NAME` to a static method returning `"hydrate-1"`, mirroring the `McpServerIT` override pattern. - Replace the three flat `Duration ttlTools/ttlResources/ttlPrompts` fields on `McpCacheConfig` with a nested `McpCacheTtlConfig` (built via `McpCacheConfigBuilder.ttl()` returning `McpCacheTtlConfigBuilder`). `McpOptionsConfigAdapter` serializes and deserializes the nested form. https://claude.ai/code/session_01WNsipAt3RGwQoeFYVxwfL8 --- .../binding/mcp/config/McpCacheConfig.java | 15 ++-- .../mcp/config/McpCacheConfigBuilder.java | 26 ++----- .../binding/mcp/config/McpCacheTtlConfig.java | 48 +++++++++++++ .../mcp/config/McpCacheTtlConfigBuilder.java | 69 +++++++++++++++++++ .../binding/mcp/config/McpOptionsConfig.java | 2 +- .../config/McpOptionsConfigAdapter.java | 26 +++---- .../mcp/internal/stream/McpProxyFactory.java | 27 +++++--- .../stream/McpProxyCacheContentionIT.java | 7 ++ .../stream/McpProxyCacheLifecycleIT.java | 7 ++ .../stream/McpProxyCachePromptsListIT.java | 7 ++ .../stream/McpProxyCacheResourcesListIT.java | 7 ++ .../stream/McpProxyCacheToolsListIT.java | 7 ++ 12 files changed, 195 insertions(+), 53 deletions(-) create mode 100644 runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/config/McpCacheTtlConfig.java create mode 100644 runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/config/McpCacheTtlConfigBuilder.java diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/config/McpCacheConfig.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/config/McpCacheConfig.java index 5e217d6048..a11486f2cf 100644 --- a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/config/McpCacheConfig.java +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/config/McpCacheConfig.java @@ -16,29 +16,22 @@ import static java.util.function.Function.identity;

charset=UTF-8 Content-Transfer-Encoding: 8bit Replace the two factory-level maps on `McpProxyFactory` (`sessions: Map` shared across all bindings, and `hydrateSessions: Long2ObjectHashMap`) with per-binding fields on `McpBindingConfig`: - `sessions: Map` — now correctly scoped per binding rather than per worker. Session ids are only meaningful within one binding's namespace. - `hydrate: McpProxyHydrate` — the per-binding hydrate session. `McpProxySession` and `McpProxyHydrate` are package-visible interfaces declared in `internal.config` so `McpBindingConfig` can type the fields without depending on the inner classes inside `McpProxyFactory`. The inner classes implement the interfaces — no behavior change. `McpLifecycleServer` gains a constructor reference to its `McpBindingConfig` so `cleanup` can call `binding.sessions.remove(sessionId)`. This sets up the per-binding hook that the upcoming per-kind factory extraction will route state through. https://claude.ai/code/session_01WNsipAt3RGwQoeFYVxwfL8 --- .../mcp/internal/config/McpBindingConfig.java | 3 + .../mcp/internal/config/McpProxyHydrate.java | 21 +++ .../mcp/internal/config/McpProxySession.java | 19 +++ .../mcp/internal/stream/McpProxyFactory.java | 124 +++++++++--------- 4 files changed, 104 insertions(+), 63 deletions(-) create mode 100644 runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpProxyHydrate.java create mode 100644 runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpProxySession.java diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java index f38820e4d8..cb9c99c1d7 100644 --- a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java @@ -18,6 +18,7 @@ import java.util.ArrayList; import java.util.List; +import java.util.Map; import java.util.Optional; import java.util.function.LongFunction; import java.util.stream.Collectors; @@ -37,6 +38,8 @@ public final class McpBindingConfig public final McpOptionsConfig options; public final GuardHandler guard; public McpListCache cache; + public Map sessions; + public McpProxyHydrate hydrate; private final List routes; diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpProxyHydrate.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpProxyHydrate.java new file mode 100644 index 0000000000..656991e88e --- /dev/null +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpProxyHydrate.java @@ -0,0 +1,21 @@ +/* + * Copyright 2021-2024 Aklivity Inc + * + * Licensed under the Aklivity Community License (the "License"); you may not use + * this file except in compliance with the License.

McpLifecycleServer (and the cross-class accessors `sender`, `originId`, `routedId`, `sessionId`, `supplyClient`) is package-private so the still-inline call/list dispatch in McpProxyFactory can pattern-match against it. McpLifecycleClient is also package-private because McpClient and McpListClient hold typed references to it. Introduce `Int2ObjectHashMap factories` on McpProxyFactory and delegate KIND_LIFECYCLE to the new factory via the dispatch table; other kinds remain inline until subsequent phases extract them. Mirrors KafkaClientFactory's per-kind factory pattern. McpProxyFactory drops 560 lines. https://claude.ai/code/session_01WNsipAt3RGwQoeFYVxwfL8 --- .../mcp/internal/stream/McpProxyFactory.java | 578 +---------- .../stream/McpProxyLifecycleFactory.java | 954 ++++++++++++++++++ 2 files changed, 963 insertions(+), 569 deletions(-) create mode 100644 runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyLifecycleFactory.java diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyFactory.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyFactory.java index 70883c079c..cc70f01654 100644 --- a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyFactory.java +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyFactory.java @@ -39,6 +39,7 @@ import org.agrona.DirectBuffer;

The base owns the shared stream state machine - the McpServer and McpClient inner classes move verbatim out of McpProxyFactory - and exposes three hooks for the kind-specific bits: protected abstract int kind(); protected abstract void injectInitialBeginEx(McpBeginExFW.Builder, String sid, String identifier); protected abstract void injectReplyBeginEx(McpBeginExFW.Builder, String sid, McpBeginExFW upstream); Each subclass implements ~30 lines: its KIND constant and the tools-call/prompts-get/resources-read variants of the BEGIN extension builder. Naming "Item" reflects that the three operations are different verbs (call/get/read) acting on a single identified MCP item - opposite to the List kinds. McpProxyFactory registers all three subclasses in its existing Int2ObjectHashMap factories map next to the Phase 2 McpProxyLifecycleFactory entry; the newStream dispatcher's else branch collapses to factories.get(kind).newStream(...). The local McpServer, McpClient, and rewriteReplyBeginEx are removed from McpProxyFactory along with three now-unused flyweight fields (flushRO, challengeRO, mcpChallengeExRW) and the McpChallengeExFW import. Net change: McpProxyFactory shrinks 735 lines (3071 -> 2336); McpProxyItemFactory adds 1229 lines. Each subclass receives the same (McpConfiguration, EngineContext, LongFunction) constructor signature as the Phase 2 lifecycle factory, and the per-factory do-helpers (doBegin, doData, doEnd, doAbort, doFlush, doChallenge, doReset, doWindow) are local copies rather than parent-shared - matches Phase 2 precedent. No visibility widening was needed beyond what Phase 2 already opened on McpLifecycleServer/McpLifecycleClient. https://claude.ai/code/session_01WNsipAt3RGwQoeFYVxwfL8 --- .../mcp/internal/stream/McpProxyFactory.java | 753 +--------- .../internal/stream/McpProxyItemFactory.java | 1229 +++++++++++++++++ 2 files changed, 1238 insertions(+), 744 deletions(-) create mode 100644 runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyItemFactory.java diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyFactory.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyFactory.java index cc70f01654..c6d40e116c 100644 --- a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyFactory.java +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyFactory.java @@ -61,7 +61,6 @@ import io.aklivity.zilla.runtime.binding.mcp.internal.types.stream.EndFW;

charset=UTF-8 Content-Transfer-Encoding: 8bit The parallel-hydrate path in McpHydrateSession.onBegin iterates over [KIND_TOOLS_LIST, KIND_RESOURCES_LIST, KIND_PROMPTS_LIST] and dispatches all three list streams on the same worker tick. The per-kind cache ITs (McpProxyCache{Resources,Prompts}ListIT.shouldHydrate{Resources,Prompts}) each only `read` their own kind's BEGIN ext, so the other two streams emit unexpected BEGINs that fail the script assertion. Updating each script to accept three BEGINs would push parallel-hydrate setup into tests whose intent is the single-kind hydrate behavior in isolation. Add MCP_HYDRATE_KIND_FILTER (IntPredicate, default `k -> true`) to McpConfiguration, exposed as `hydrateKindFilter()`. Mirrors the existing MCP_SESSION_ID supplier pattern: tests resolve a `Class::method` static reference; the decoder loads it via MethodHandle. Production keeps the default — all three kinds hydrate in parallel — so the contention IT exercises the real behavior unchanged. Each per-kind IT now configures the filter to its single KIND_*_LIST so only that kind's BEGIN is emitted and the existing per-kind scripts pass unmodified. Result locally: 3 hydrate failures fixed (McpProxyCacheToolsListIT had timed out, also resolved). Three `shouldServe*` failures remain — cache-serve reads empty payload — and are independent of hydrate dispatch. https://claude.ai/code/session_01WNsipAt3RGwQoeFYVxwfL8 --- .../mcp/internal/McpConfiguration.java | 37 +++++++++++++++++++ .../mcp/internal/stream/McpProxyFactory.java | 7 ++++ .../mcp/internal/McpConfigurationTest.java | 3 ++ .../stream/McpProxyCachePromptsListIT.java | 11 ++++++ .../stream/McpProxyCacheResourcesListIT.java | 11 ++++++ .../stream/McpProxyCacheToolsListIT.java | 10 +++++ 6 files changed, 79 insertions(+) diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/McpConfiguration.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/McpConfiguration.java index 59e74a7614..37cc50f3a3 100644 --- a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/McpConfiguration.java +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/McpConfiguration.java @@ -23,6 +23,7 @@ import java.time.Duration;

Introduce an abstract McpProxyListFactory implementing BindingHandler plus three concrete per-kind subclasses (McpProxyToolsListFactory, McpProxyPromptsListFactory, McpProxyResourcesListFactory). The base owns the shared state machine - McpListClient, McpListClientDecoder with its ten decode states, McpListServer (passthrough), and McpCacheListServer (cache-serve variant), plus the indexOfByte JSON helper - and exposes seven hooks for the kind-specific bits: protected abstract int kind(); protected abstract void injectInitialBeginEx(McpBeginExFW.Builder, String sid); protected abstract void injectReplyBeginEx(McpBeginExFW.Builder, String sid); protected abstract DirectBuffer listReplyOpenPrelude(); protected abstract JsonParserFactory listItemParserFactory(); protected abstract String arrayKey(); protected abstract String idKey(); Each subclass owns its per-kind prelude bytes (the JSON envelope-open literal), JsonParserFactory for the streaming item parser, array key ("tools" / "prompts" / "resources"), and id key ("name" or "uri" for resources). The kind field is removed from McpListClient, McpListServer, and McpCacheListServer - each factory instance is bound to one kind, so the seven `switch (kind)` blocks in those classes collapse to direct hook calls. Cache-vs-passthrough is now dispatched internally in McpProxyListFactory.newStream: when binding.cache is non-null an McpCacheListServer is constructed, otherwise an McpListServer with its McpListClient via lifecycle.supplyClient. The McpProxyFactory factories map gets three new entries (KIND_TOOLS_LIST / KIND_PROMPTS_LIST / KIND_RESOURCES_LIST) and the newStream dispatcher collapses to factories.get(kind).newStream(...) for every dispatched kind, including lifecycle - the per-kind factories enforce their own session/route preconditions. HydrateListStream, McpHydrateSession, and SIGNAL_INITIATE_HYDRATE stay in McpProxyFactory because they coordinate multi-kind hydrate from one session and aren't request-time dispatch paths; the small kind-switch in HydrateListStream.initiate persists. McpProxyFactory shrinks 1777 lines (2343 -> 566), shedding all list machinery plus six now-unused do* helpers (doBegin, doData, doAbort, two doFlush overloads, doChallenge, doReset), unused flyweight RO/RW fields and imports, and the no-longer-called sessionId(McpBeginExFW) helper. doEnd, doWindow, and a local newStream remain because HydrateListStream still calls them. McpProxyListFactory adds 2016 lines. No further visibility widening was needed beyond what Phase 2 opened on the lifecycle accessors. ITs: 156 pass / 3 fail / 8 skipped, identical to the pre-refactor baseline. The three `shouldServe*` failures are a pre-existing cache-serve empty-payload bug unrelated to this refactor. https://claude.ai/code/session_01WNsipAt3RGwQoeFYVxwfL8 --- .../mcp/internal/stream/McpProxyFactory.java | 1877 +-------------- .../internal/stream/McpProxyListFactory.java | 2016 +++++++++++++++++ 2 files changed, 2066 insertions(+), 1827 deletions(-) create mode 100644 runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyListFactory.java diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyFactory.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyFactory.java index 84656dda31..a88dd5de74 100644 --- a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyFactory.java +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyFactory.java @@ -21,23 +21,15 @@ import static io.aklivity.zilla.runtime.binding.mcp.internal.types.stream.McpBeginExFW.KIND_RESOURCES_READ;

Make these ITs deterministic by pre-seeding the cache instead of racing against hydrate. Mid-hydrate is a distinct scenario that lifecycle gating will cover later (the .hydrating scripts and @Ignore'd shouldServe*ListHydrating methods are removed here; when lifecycle gating lands we'll re-introduce a clearer cache.serve..refreshing flavor rather than overload "hydrating"). Changes: - New config proxy.cache.seeded.yaml using TestStore with options.entries carrying the tools/resources/prompts JSON. The existing proxy.cache.yaml is unchanged - hydrate ITs continue to verify an empty memory store. - Runtime shouldServe{Tools,Resources,Prompts}List ITs switch to proxy.cache.seeded.yaml and reuse the existing cache.hydrate/server script for the downstream (it only handles the hydrate-1 lifecycle accept + reply, which is exactly what a fully-cached binding produces on the wire when McpHydrateSession.onBegin sees every cache.get returning non-null and spawns no list streams). - Delete the three .hydrating script directories and the @Ignore'd shouldServe*ListHydrating test methods (both runtime and peer ITs). Runtime: 156 pass / 0 fail / 5 skipped (was 156p / 3f / 8s). Peer: 15 pass / 0 fail / 0 skipped. https://claude.ai/code/session_01WNsipAt3RGwQoeFYVxwfL8 --- .../stream/McpProxyCachePromptsListIT.java | 16 +---- .../stream/McpProxyCacheResourcesListIT.java | 16 +---- .../stream/McpProxyCacheToolsListIT.java | 16 +---- .../mcp/config/proxy.cache.seeded.yaml | 33 ++++++++++ .../client.rpt | 56 ----------------- .../server.rpt | 62 ------------------ .../client.rpt | 56 ----------------- .../server.rpt | 62 ------------------ .../client.rpt | 56 ----------------- .../server.rpt | 63 ------------------- .../cache/ProxyCachePromptsListIT.java | 9 --- .../cache/ProxyCacheResourcesListIT.java | 9 --- .../streams/cache/ProxyCacheToolsListIT.java | 9 --- 13 files changed, 39 insertions(+), 424 deletions(-) create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/config/proxy.cache.seeded.yaml delete mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.serve.prompts.list.hydrating/client.rpt delete mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.serve.prompts.list.hydrating/server.rpt delete mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.serve.resources.list.hydrating/client.rpt delete mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.serve.resources.list.hydrating/server.rpt delete mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.serve.tools.list.hydrating/client.rpt delete mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.serve.tools.list.hydrating/server.rpt diff --git a/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCachePromptsListIT.java b/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCachePromptsListIT.java index 2a9e1e2d48..faaddce1b8 100644 --- a/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCachePromptsListIT.java +++ b/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCachePromptsListIT.java @@ -67,10 +67,10 @@ public void shouldHydratePrompts() throws Exception } @Test - @Configuration("proxy.cache.yaml") + @Configuration("proxy.cache.seeded.yaml") @Specification({ "${app}/cache.serve.prompts.list/client", - "${app}/cache.hydrate.prompts/server" }) + "${app}/cache.hydrate/server" }) @ScriptProperty("serverAddress \"zilla://streams/app1\"") public void shouldServePromptsList() throws Exception { @@ -88,18 +88,6 @@ public void shouldRefreshPrompts() throws Exception k3po.finish();

By the time an agent's lifecycle is "initialized" from its point of view, every list method served by this binding is in the cache - subsequent tools/list, resources/list, prompts/list requests get a synchronous cache hit and never race the hydrate path. Bindings with no cache configured retain the previous synchronous BEGIN-reply behavior (binding.hydrate == null branch). Mechanism uses the engine's existing signal infrastructure: - McpHydrateSession tracks totalKinds (computed from the filter) and settledKinds. Each kind settles either from cache.get returning non-null at hydrate startup (pre-seeded store) or from the matching HydrateListStream's terminal write (cache.put completion, bodyLen==0 skip-put, or abort/reset). Once settledKinds == totalKinds, the session flips the complete latch and fires signaler.signalNow against every pending agent stream registered via awaitComplete. - McpProxyHydrate gains awaitComplete(originId, routedId, streamId, traceId, signalId). When complete is already true the signal fires immediately (synchronous fast path for the pre-seeded case); otherwise the (streamId, signalId) pair is queued. cleanup discards pending before tearing the session down. - McpProxyLifecycleFactory.McpLifecycleServer.onServerBegin now transitions initial state and emits WINDOW synchronously, then delegates the BEGIN reply via binding.hydrate.awaitComplete using the agent's reply-id as the signal target (the engine registers the binding's stream consumer in throttles[replyId], so SignalFW for that stream id routes back to onServerMessage). A new SignalFW case dispatches to onServerSignal, which fires doDeferredServerBegin for SIGNAL_HYDRATE_COMPLETE. The deferred path guards on replyOpened/replyClosed in case the agent abandoned before complete fired, and rebuilds beginEx inside the deferred path so the shared codecBuffer is fresh at fire time. - HydrateListStream now holds a back-reference to its parent McpHydrateSession (passed via the constructor) and a settled flag to dedupe completion when both onEnd and abort/reset fire on the same stream. McpProxyCacheLifecycleIT.shouldServeInitialize switches to proxy.cache.seeded.yaml: an empty memory store would block forever because the hydrate session's three list streams find no cooperating downstream in cache.hydrate/server. With the pre-seeded test store the hydrate session sees every cache.get return non-null synchronously, the complete latch flips before the agent's lifecycle arrives, and the deferred BEGIN reply takes the synchronous fast path.

charset=UTF-8 Content-Transfer-Encoding: 8bit McpHydrateSession now uses signaler.signalAt to re-issue list-kind hydrate streams when the per-kind TTL elapses. Scheduling fires: - After each kind's initial hydrate completes (HydrateListStream reaches its terminal: cache.put completion, bodyLen==0 skip-put, or abort/reset — same gating dedupe applies, so each instance schedules at most one next refresh). - After each cache.get returns non-null at startup (pre-seeded value still refreshes on TTL, so the value stays fresh). - After each refresh stream's terminal (recursive, same code path). Each kind has its own signal id (SIGNAL_REFRESH_{TOOLS,RESOURCES, PROMPTS}) and TTL (McpCacheTtlConfig.tools / .resources / .prompts). When ttlForKind returns null (no cache.ttl block, or the block omits that kind), no refresh is scheduled - the cache value stays forever. On abort/reset of an in-flight refresh, the cache.put never fires, so the prior cached value is preserved (the test that validates this behaviour is now un-ignored as shouldRefreshToolsError). McpHydrateSession.settle takes the kind explicitly and both contributes to the initial-hydrate gating latch and schedules the next refresh. HydrateListStream forwards its kind into parent.settle(kind) - no behavioural change to the gating dedupe. McpProxyCache{Tools,Resources,Prompts}ListIT.shouldRefresh* and shouldRefreshToolsError no longer @Ignore - now run against proxy.cache.refresh.yaml (ttl tools=PT1S, resources=PT2S, prompts=PT3S) via the existing cache.refresh. / cache.refresh..error spec scripts.

The McpHydrateSession and HydrateListStream now stamp that token onto every outbound BEGIN/END/WINDOW in place of the prior hardcoded 0L authorization, so any downstream binding that runs a guard recognises the cache hydrate session as an authenticated principal. The map is constrained to a single guard entry by the schema patch (maxProperties: 1 under cache.authorization); the runtime picks that entry via iterator without defensive assertion, since invalid yaml is rejected at config-load time. Token freshness is left to the guard for now - the binding does not re-reauthorize per BEGIN. If a future guard implementation needs short-lived tokens, the call site is a single line and can move to per-stream resolution without changing the API shape. New test scaffolding: - specs/.../config/proxy.cache.auth.yaml - engine test_guard + test store pre-seeded with empty list payloads (so hydrate spawns no list streams; the authorization assertion lands on the lifecycle BEGIN alone) + proxy declaring cache.authorization.test_guard with matching credentials. - specs/.../streams/application/cache.hydrate.auth/{client,server}.rpt mirrors cache.hydrate/ but adds option zilla:authorization 1L (the TestGuard's first reauthorize result) to assert the proxy stamps the expected long on its hydrate BEGIN. - shouldHydrateAuth peer IT in ProxyCacheLifecycleIT and engine-driven IT in McpProxyCacheLifecycleIT.

Coordinate via the configured store's putIfAbsent so exactly one worker issues each call. Two leases, one shared key namespace on the configured store: - Binding-wide "lifecycle.lock": acquired before opening the hydrate lifecycle stream to downstream. Loser polls every 100ms until the lock frees; winner holds it through the initial hydrate. Released inside markComplete once every kind permitted by the filter has settled, so other workers can then open their own lifecycle (independent stream onward) and observe the now-populated cache. - Per-kind ".lock": acquired before issuing a HydrateListStream (both initial and refresh paths). Loser at initial-hydrate time markSettled-s without scheduling a refresh - the lease holder owns refresh scheduling because settle (gated by the per-stream settled flag) is the only path that calls scheduleRefresh. Released after cache.put completes (or after onEnd's skip-put branch, or after an abort/reset terminal) and before parent.settle fires. settle is split into markSettled (gating-latch only) and settle (markSettled + scheduleRefresh). cache hits at startup, lease losses at initial hydrate, and lease losses at refresh-time all funnel through markSettled so they contribute to lifecycle gating without arming a refresh signal on a worker that didn't actually do the work. McpProxyCacheContentionIT (was class-level @Ignore'd) is now enabled, configured with MCP_HYDRATE_KIND_FILTER restricting to KIND_TOOLS_LIST (since cache.refresh.tools.contended/server.rpt only models the tools exchanges; resources and prompts are not in scope for this scenario). hydrateSessionId now cycles "hydrate-A"/"hydrate-B" per call so the two workers' attach-time calls match the script's session ids. Lease TTLs: - lifecycle: 30s (safety net for crashes; explicit release covers the happy path). - per-kind: 30s ditto. - Retry polling for lifecycle: 100ms. Verified: 157 pass / 0 fail / 0 skipped. Every test that was @Ignore'd at the start of the PR is now active and green. https://claude.ai/code/session_01WNsipAt3RGwQoeFYVxwfL8 --- .../mcp/internal/config/McpListCache.java | 39 +++++++++++ .../mcp/internal/stream/McpProxyFactory.java | 65 +++++++++++++++++-- .../stream/McpProxyCacheContentionIT.java | 19 +++++- 3 files changed, 113 insertions(+), 10 deletions(-) diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpListCache.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpListCache.java index a4a17d2b65..14f5f0b37d 100644 --- a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpListCache.java +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpListCache.java @@ -28,6 +28,9 @@ public final class McpListCache private static final String STORE_KEY_TOOLS = "tools";

No TTL behaviour was added — production binding code releases leases explicitly, and the existing skip-TTL semantics is sufficient for the cache test scenarios. binding-mcp switches its three remaining memory-store configs (proxy.cache.yaml, proxy.cache.refresh.yaml, proxy.cache.toolkit.yaml) to type: test, matching the dependency hygiene rule that implementations must not depend on other implementations - the cache ITs now run entirely against the engine's test-jar store. The store-memory test dependency drops out of runtime/binding-mcp/pom.xml. Verified: 157 pass / 0 fail / 0 skipped (all cache ITs, McpServerIT, McpClientIT, McpProxyIT, McpProxyCacheContentionIT) and the engine spec IT suite (39 / 0 / 0) — no regression in either project from the TestStore sharing change. https://claude.ai/code/session_01WNsipAt3RGwQoeFYVxwfL8 --- runtime/binding-mcp/pom.xml | 6 ------ .../engine/test/internal/store/TestStore.java | 13 ++++++++++++- .../test/internal/store/TestStoreContext.java | 14 +++++++++----- .../test/internal/store/TestStoreHandler.java | 9 ++++----- .../binding/mcp/config/proxy.cache.refresh.yaml | 2 +- .../binding/mcp/config/proxy.cache.toolkit.yaml | 2 +- .../specs/binding/mcp/config/proxy.cache.yaml | 2 +- 7 files changed, 28 insertions(+), 20 deletions(-) diff --git a/runtime/binding-mcp/pom.xml b/runtime/binding-mcp/pom.xml index ff4f4d6271..47eba155fb 100644 --- a/runtime/binding-mcp/pom.xml +++ b/runtime/binding-mcp/pom.xml @@ -84,12 +84,6 @@ ${project.version} provided - - ${project.groupId} - store-memory - ${project.version} - test - diff --git a/runtime/engine/src/test/java/io/aklivity/zilla/runtime/engine/test/internal/store/TestStore.java b/runtime/engine/src/test/java/io/aklivity/zilla/runtime/engine/test/internal/store/TestStore.java index d0c412912d..c4276685ff 100644 --- a/runtime/engine/src/test/java/io/aklivity/zilla/runtime/engine/test/internal/store/TestStore.java +++ b/runtime/engine/src/test/java/io/aklivity/zilla/runtime/engine/test/internal/store/TestStore.java @@ -16,6 +16,8 @@ package io.aklivity.zilla.runtime.engine.test.internal.store;

the actual dispatch (parse BEGIN ext, look up by kind, delegate to a per-kind factory) was a small slice of that. The rest - McpHydrateSession, McpHydrateListStream, the SIGNAL_INITIATE_HYDRATE / SIGNAL_REFRESH_* / LEASE_TTL_MS / LEASE_RETRY_MS constants, the PendingAwait record, the local newStream/doEnd/doWindow helpers, the cache attach wiring (store resolve, McpListCache instantiate, cacheGuard reauthorize, McpHydrateSession construct, schedule SIGNAL_INITIATE_HYDRATE), and the matching detach cleanup - is now owned by a new sibling McpCacheHydrater. McpCacheHydrater exposes attach(McpBindingConfig) and detach(McpBindingConfig) mirroring the BindingHandler lifecycle the engine drives. McpProxyFactory constructs one in its ctor and delegates both calls. McpProxyFactory drops from 795 lines to 136 (a pure dispatcher now): keeps the factories map and its seven per-kind registrations, the bindings map, supplyGuard for McpBindingConfig construction, mcpBeginExRO/beginRO for parsing the inbound BEGIN to extract the kind, and the new hydrater field. McpCacheHydrater is 724 lines holding everything cache-hydrate: signal ids, lease ttls/retry, PendingAwait record, McpHydrateSession (still implementing McpProxyHydrate so McpProxyLifecycleFactory can defer the agent BEGIN reply via awaitComplete), McpHydrateListStream (settle / cache.put / lease release path unchanged), and per-worker flyweights duplicated for the hydrate stream-write helpers. The hydrate session keeps its own codecBuffer (separate UnsafeBuffer allocated against writeBuffer.capacity), matching the per-handler flyweight pattern. McpBindingConfig gains one accessor: long resolveId(String name) plus the corresponding private ToLongFunction field initialized from binding.resolveId. Needed because McpCacheHydrater.attach receives only the wrapped McpBindingConfig and must resolve the cache store name to a binding id at attach time. Cleaner than passing the raw BindingConfig alongside. Verified: 158 pass / 0 fail / 0 skipped (identical to pre-refactor baseline). Checkstyle 0 violations.

lives in its own file in the stream package. - #3 acquire-lifecycle-lease callback is a named method reference rather than an inline lambda; traceId is re-supplied inside the method body via supplyTraceId.getAsLong() instead of captured. - #4 doLifecycleBegin guard inverted to wrap the body, single return per method. - #5 separate signal handlers per kind; initial population is the first refresh. The binding-level orchestrator (McpProxyCacheHydrater) owns the lifecycle stream and tracks readiness via a populated counter rather than a totalKinds/settledKinds pair on a McpHydrateSession. Per-kind work moves into McpProxyCacheListHydrater (abstract base) with three concrete subclasses (McpProxyCacheToolsListHydrater / ResourcesListHydrater / PromptsListHydrater), mirroring the McpProxyListFactory hierarchy. - #6 cleanup's inline doEnd / state update is consolidated into a standard doInitialEnd helper on McpProxyCacheHydrater. Kind and signal id are passed via the abstract base's constructor as protected final fields rather than abstract methods - only the truly kind-specific behaviour (injectInitialBeginEx and ttl()) remains abstract. Each concrete subclass collapses to ~15 lines. McpProxyHydrate interface and the old McpCacheHydrater are deleted. McpProxyLifecycleFactory now calls binding.hydrater.register(handle) directly with an McpSignalHandle instance instead of going through an interface. McpListCache stays at its current public surface (get / put / acquireLease / releaseLease / acquireLifecycleLease / releaseLifecycleLease) - the readiness tracking lives on the orchestrator because it already knows the filtered kind set from hydrateKindFilter at attach time, so no expecting(kind) plumbing was needed. Files: - McpProxyHydrate.java deleted - McpCacheHydrater.java deleted (replaced) - McpProxyCacheHydrater.java new - per-binding orchestrator - McpProxyCacheListHydrater.java new - abstract base + 3 subclasses - McpSignalHandle.java new - McpBindingConfig.java - supplyStore ctor param, cache field initialised in ctor, hydrate field renamed to hydrater and retyped - McpProxyFactory.java - per-binding hydrater instantiation in attach - McpProxyLifecycleFactory.java - binding.hydrater.register instead of binding.hydrate.awaitComplete - McpClientFactory.java - 1-line ctor signature update for the now 3-arg McpBindingConfig ctor Verified: 158 pass / 0 fail / 0 skipped, identical to baseline.

Three files affected, nine new files created: McpProxyItemFactory.java (1229 -> 1124) loses three subclasses: - McpProxyToolsCallFactory.java - McpProxyPromptsGetFactory.java - McpProxyResourcesReadFactory.java McpProxyListFactory.java (2016 -> 1819) loses three subclasses: - McpProxyToolsListFactory.java - McpProxyPromptsListFactory.java - McpProxyResourcesListFactory.java McpProxyCacheListHydrater.java (329 -> 257) loses three subclasses: - McpProxyCacheToolsListHydrater.java - McpProxyCacheResourcesListHydrater.java - McpProxyCachePromptsListHydrater.java Each new file has the standard Aklivity Community License header, a minimal import set (alphabetical within groups), and contains only the final class declaration extending the base. Base files trim imports that were only used by the lifted subclasses (Map and StreamingJson out of McpProxyListFactory; KIND_TOOLS_LIST / KIND_RESOURCES_LIST / KIND_PROMPTS_LIST static imports out of McpProxyCacheListHydrater). No visibility widening was needed - subclasses already touched only protected abstract hooks on the bases or package-private fields on parent objects. Verified: 158 pass / 0 fail / 0 skipped. Checkstyle 0 violations. https://claude.ai/code/session_01WNsipAt3RGwQoeFYVxwfL8 --- .../stream/McpProxyCacheListHydrater.java | 72 ------- .../McpProxyCachePromptsListHydrater.java | 44 ++++ .../McpProxyCacheResourcesListHydrater.java | 44 ++++ .../McpProxyCacheToolsListHydrater.java | 44 ++++ .../internal/stream/McpProxyItemFactory.java | 105 ---------- .../internal/stream/McpProxyListFactory.java | 197 ------------------ .../stream/McpProxyPromptsGetFactory.java | 57 +++++ .../stream/McpProxyPromptsListFactory.java | 96 +++++++++ .../stream/McpProxyResourcesListFactory.java | 96 +++++++++ .../stream/McpProxyResourcesReadFactory.java | 57 +++++ .../stream/McpProxyToolsCallFactory.java | 57 +++++ .../stream/McpProxyToolsListFactory.java | 96 +++++++++ 12 files changed, 591 insertions(+), 374 deletions(-) create mode 100644 runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCachePromptsListHydrater.java create mode 100644 runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCacheResourcesListHydrater.java create mode 100644 runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCacheToolsListHydrater.java create mode 100644 runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyPromptsGetFactory.java create mode 100644 runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyPromptsListFactory.java create mode 100644 runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyResourcesListFactory.java create mode 100644 runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyResourcesReadFactory.java create mode 100644 runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyToolsCallFactory.java create mode 100644 runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyToolsListFactory.java diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCacheListHydrater.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCacheListHydrater.java index addb42ab7e..f3ddf9ede6 100644 --- a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCacheListHydrater.java +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCacheListHydrater.java @@ -14,9 +14,6 @@ */ package io.aklivity.zilla.runtime.binding.mcp.internal.stream; -import static io.aklivity.zilla.runtime.binding.mcp.internal.types.stream.McpBeginExFW.KIND_PROMPTS_LIST; -import static io.aklivity.zilla.runtime.binding.mcp.internal.types.stream.McpBeginExFW.KIND_RESOURCES_LIST; -import static io.aklivity.zilla.runtime.binding.mcp.internal.types.stream.McpBeginExFW.KIND_TOOLS_LIST; import static java.lang.System.currentTimeMillis; import java.nio.charset.StandardCharsets; @@ -258,72 +255,3 @@ private void terminal( } } } - -final class McpProxyCacheToolsListHydrater extends McpProxyCacheListHydrater -{ - McpProxyCacheToolsListHydrater( - McpProxyCacheHydrater parent) - { - super(parent, KIND_TOOLS_LIST, SIGNAL_REFRESH_TOOLS); - } - - @Override - protected void injectInitialBeginEx( - McpBeginExFW.Builder b, - String sessionId) - { - b.toolsList(t -> t.sessionId(sessionId)); - } - - @Override - protected Duration ttl() - { - return parent.binding.options.cache.ttl != null ?

No real-world signal that the per-kind knobs are needed; can be reintroduced additively if/when a use case appears.

Schema is unchanged (options.cache.authorization remains a single-entry guard-name map at the YAML level); the adapter now flattens the single map entry into the McpAuthorizationConfig fields on read and back to a single entry on write. The Map.Entry/Iterator dance in McpBindingConfig drops out — the cache guard and credentials read directly off the McpAuthorizationConfig. Note: at runtime there is no overlap between options.authorization (server/client kinds) and options.cache.authorization (proxy kind), so the type reuse is purely structural — credentials remains unused at the top-level site for now.

Now the hydrater self-targets binding.id, letting the binding's own dispatch fan out across all routes via McpProxyListFactory's McpListServer aggregation path — the same code path that serves uncached agent list calls. - McpProxyCacheHydrater: routedId = binding.id (self-loop); drop pre-resolution and the `enabled` field; lifecycle acquired unconditionally on start. - McpProxyListFactory.newStream: detect self-loop (originId == routedId) and skip the cache server, falling through to McpListServer aggregation so the hydrater observes the merged result rather than serving from its own empty cache. - McpProxyLifecycleFactory.onServerBegin: when self-loop, bypass the hydrate-complete gating that otherwise defers the lifecycle reply BEGIN — the hydrater's own lifecycle would deadlock waiting for itself.

All three list-kind streams arrive at app1 (lifecycle plus tools/list, resources/list, prompts/list), not just one — the previously incomplete scripts only happened to pass because the legacy direct-route hydrate did not surface them through McpListServer at app0. - cache.hydrate.error: extend server.rpt and client.rpt to handle all three list kinds; tools aborts, resources and prompts succeed so the remaining caches still populate. - cache.refresh.tools.contended: simplify to one lifecycle plus two tools/list streams (initial + refresh); the per-kind lease ensures only one worker's call reaches app1 per round. - Rename proxy.cache.auth.yaml to proxy.cache.credentials.yaml and cache.hydrate.auth/ scripts to cache.hydrate.credentials/; rename shouldHydrateAuth to shouldHydrateWithCredentials in both ITs. All 157 engine-driven binding-mcp ITs and the spec peer-to-peer ITs pass; the three previously @Ignored scenarios are now active. https://github.com/aklivity/zilla/pull/1774 --- .../stream/McpProxyCacheContentionIT.java | 2 - .../stream/McpProxyCacheLifecycleIT.java | 9 +- ...auth.yaml => proxy.cache.credentials.yaml} | 5 - .../application/cache.hydrate.auth/client.rpt | 37 ------- .../cache.hydrate.credentials/client.rpt | 103 ++++++++++++++++++ .../server.rpt | 60 ++++++++++ .../cache.hydrate.error/client.rpt | 42 +++++++ .../cache.hydrate.error/server.rpt | 41 ++++++- .../cache.refresh.tools.contended/client.rpt | 31 +----- .../cache.refresh.tools.contended/server.rpt | 19 ---- .../streams/cache/ProxyCacheLifecycleIT.java | 6 +- 11 files changed, 255 insertions(+), 100 deletions(-) rename specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/config/{proxy.cache.auth.yaml => proxy.cache.credentials.yaml} (87%) delete mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.hydrate.auth/client.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.hydrate.credentials/client.rpt rename specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/{cache.hydrate.auth => cache.hydrate.credentials}/server.rpt (55%) diff --git a/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCacheContentionIT.java b/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCacheContentionIT.java index e094bffa62..968137a537 100644 --- a/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCacheContentionIT.java +++ b/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCacheContentionIT.java @@ -24,7 +24,6 @@ import java.util.concurrent.atomic.AtomicInteger;

cache.hydrate.prompts were subsets of cache.hydrate (multi-kind): each only asserted "lifecycle BEGIN + one kind's list BEGIN", which the multi-kind scenario already verifies. The lifecycle-reuse property is structural (McpLifecycleClient.supplyClient with computeIfAbsent) and is exercised by the multi-kind scenario. Drop the three per-kind hydrate script directories and the shouldHydrateTools / shouldHydrateResources / shouldHydratePrompts test methods from both the engine-driven and peer-to-peer ITs. The per-kind ITs keep their shouldServe* and shouldRefresh* methods, which still benefit from MCP_HYDRATE_FILTER scoping the refresh path to one kind. https://github.com/aklivity/zilla/pull/1774 --- .../stream/McpProxyCachePromptsListIT.java | 10 --- .../stream/McpProxyCacheResourcesListIT.java | 10 --- .../stream/McpProxyCacheToolsListIT.java | 10 --- .../cache.hydrate.prompts/client.rpt | 62 ------------- .../cache.hydrate.prompts/server.rpt | 66 -------------- .../cache.hydrate.resources/client.rpt | 64 -------------- .../cache.hydrate.resources/server.rpt | 68 --------------- .../cache.hydrate.tools/client.rpt | 83 ------------------ .../cache.hydrate.tools/server.rpt | 87 ------------------- .../cache/ProxyCachePromptsListIT.java | 9 -- .../cache/ProxyCacheResourcesListIT.java | 9 -- .../streams/cache/ProxyCacheToolsListIT.java | 9 -- 12 files changed, 487 deletions(-) delete mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.hydrate.prompts/client.rpt delete mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.hydrate.prompts/server.rpt delete mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.hydrate.resources/client.rpt delete mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.hydrate.resources/server.rpt delete mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.hydrate.tools/client.rpt delete mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.hydrate.tools/server.rpt diff --git a/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCachePromptsListIT.java b/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCachePromptsListIT.java index c1a4d8adc8..9fa573377a 100644 --- a/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCachePromptsListIT.java +++ b/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCachePromptsListIT.java @@ -55,16 +55,6 @@ public class McpProxyCachePromptsListIT @Rule public final TestRule chain = outerRule(engine).around(k3po).around(timeout);

The previously-orphan proxy.cache.toolkit.yaml is now referenced by a test.

Inline McpProxyCacheListHydrater plus its three kind-specific subclasses as inner classes of McpProxyCacheHydrater so they share the outer flyweights and reach session/authorization directly through the enclosing context, dropping the LongSupplier / Supplier indirections.

The three per-kind hydraters collapse to three stateless strategy fields on the outer; all state-machine methods take an McpCacheContext parameter and thread it through. McpCacheContext moves into internal.stream and absorbs the session state (awaiters, populated, expected, complete, sessionId, authorization) plus the bare-method-ref signal targets (onInitiateLifecycle, onRefresh, register). Active stream handlers register opaque Runnable cleanup hooks so detach can end them without the context importing inner stream types. McpBindingConfig drops the per-binding hydrater field; the lifecycle factory now registers awaiters via binding.cacheContext.register. --- .../mcp/internal/config/McpBindingConfig.java | 4 +- .../{config => stream}/McpCacheContext.java | 115 +++++- .../stream/McpProxyCacheHydrater.java | 373 +++++++++++------- .../mcp/internal/stream/McpProxyFactory.java | 10 +- .../stream/McpProxyLifecycleFactory.java | 5 +- .../internal/stream/McpProxyListFactory.java | 1 - .../stream/McpProxyPromptsListFactory.java | 1 - .../stream/McpProxyResourcesListFactory.java | 1 - .../stream/McpProxyToolsListFactory.java | 1 - 9 files changed, 344 insertions(+), 167 deletions(-) rename runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/{config => stream}/McpCacheContext.java (67%) diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java index e7698cb5e5..878d2f8dc8 100644 --- a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java @@ -28,7 +28,7 @@ import io.aklivity.zilla.runtime.binding.mcp.config.McpAuthorizationConfig; import io.aklivity.zilla.runtime.binding.mcp.config.McpOptionsConfig; import io.aklivity.zilla.runtime.binding.mcp.internal.McpConfiguration; -import io.aklivity.zilla.runtime.binding.mcp.internal.stream.McpProxyCacheHydrater; +import io.aklivity.zilla.runtime.binding.mcp.internal.stream.McpCacheContext; import io.aklivity.zilla.runtime.binding.mcp.internal.types.stream.HttpBeginExFW; import io.aklivity.zilla.runtime.binding.mcp.internal.types.stream.McpBeginExFW; import io.aklivity.zilla.runtime.engine.EngineContext; @@ -46,7 +46,6 @@ public final class McpBindingConfig public final GuardHandler guard; public final McpCacheContext cacheContext; public final Map sessions; - public McpProxyCacheHydrater hydrater; private final List routes; @@ -99,7 +98,6 @@ public McpBindingConfig( config.leaseTtl(), config.leaseRetry(), cacheTtl) : null; this.sessions = new Object2ObjectHashMap<>(); - this.hydrater = cacheContext != null ? new McpProxyCacheHydrater(cacheContext, config, context) : null; } public McpRouteConfig resolve( diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpCacheContext.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpCacheContext.java similarity index 67% rename from runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpCacheContext.java rename to runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpCacheContext.java index d0a7dddd1e..a65d44c562 100644 --- a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpCacheContext.java +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpCacheContext.java @@ -12,13 +12,15 @@ * WARRANTIES OF ANY KIND, either express or implied.

Signal scheduling sites use small context-capturing lambdas to invoke hydrater methods directly (sigId -> beginLifecycle(context) and sigId -> refresh(context)), so the trampoline methods onInitiateLifecycle and onRefresh on the context are gone too. McpCacheContext now takes the engine Signaler at construction time (provided via McpBindingConfig from EngineContext) which it uses directly for handle dispatch in register() and markComplete(). The detached guard moves into beginLifecycle and refresh on the hydrater where the orchestration actually happens. bind(hydrater, expected) becomes prepare(expected) — just session state reset, no hydrater stored. The lambda allocation per signal scheduling fires at most a handful of times per binding lifetime (attach, lease retry, cache TTL refresh) — nothing on the hot path. --- .../mcp/internal/config/McpBindingConfig.java | 2 +- .../mcp/internal/stream/McpCacheContext.java | 31 ++++---------- .../stream/McpProxyCacheHydrater.java | 41 +++++++------------ 3 files changed, 22 insertions(+), 52 deletions(-) diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java index 878d2f8dc8..1e021e2efc 100644 --- a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java @@ -94,7 +94,7 @@ public McpBindingConfig( .orElse(null);

charset=UTF-8 Content-Transfer-Encoding: 8bit McpCacheContext takes the per-worker hydrater as a final ctor field and owns the full lifecycle state machine. McpProxyFactory.attach calls context.start() (no args) and context.detach() directly; the hydrater's attach/detach/beginLifecycle/onAcquireLifecycleComplete methods are gone. The signaler also lives on context (final ctor field, used directly by register/markComplete and by the state-machine methods). Hydrater no longer holds a signaler reference. Signal callbacks are bare method refs targeting context methods — this::beginLifecycle, this::onRefresh — so zero allocation per signal scheduling. The detached guard and lifecycle orchestration read top-to-bottom on context, where the session state lives. Hydrater becomes pure plumbing: flyweights, per-kind strategies, suppliers, plus accessors (activeHydraterCount, supplyTraceId, supplySessionId), a lifecycle-stream factory (newLifecycleStream), a list-hydrater dispatcher (initiateListHydraters), and the per-kind refresh dispatcher (refresh). The list-hydrater refresh-timing also flows through context: strategies call context.scheduleRefresh(signalId()) instead of touching signaler directly. cacheTtl gating is on context where cacheTtl already lives. McpHydrateLifecycleStream becomes package-private so context can hold a typed reference (replacing the prior Runnable cleanup hook). On stream BEGIN the stream notifies context.onLifecycleOpened so context can dispatch list hydraters; on stream close paths the stream notifies context.onLifecycleClosed so context can drop the typed reference and release the lock. The future reconnect hook will live in onLifecycleClosed. McpBindingConfig accepts the hydrater as a 4th ctor param and threads it to McpCacheContext. McpServerFactory and McpClientFactory pass null since they never construct a cache. --- .../mcp/internal/config/McpBindingConfig.java | 6 +- .../mcp/internal/stream/McpCacheContext.java | 103 ++++++++++++++-- .../mcp/internal/stream/McpClientFactory.java | 2 +- .../stream/McpProxyCacheHydrater.java | 110 ++++++------------ .../mcp/internal/stream/McpProxyFactory.java | 6 +- .../mcp/internal/stream/McpServerFactory.java | 2 +- 6 files changed, 137 insertions(+), 92 deletions(-) diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java index 1e021e2efc..5562da8632 100644 --- a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java @@ -29,6 +29,7 @@ import io.aklivity.zilla.runtime.binding.mcp.config.McpOptionsConfig;

charset=UTF-8 Content-Transfer-Encoding: 8bit Three related cleanups to the cache hydrate lifecycle: 1. Defer expensive work until lock acquired. beginLifecycle now just calls acquireLifecycle; the traceId, sessionId, and guard reauthorization happen inside onAcquireLifecycleComplete only when acquired == true. Avoids minting a sessionId / reauthorizing the guard on every failed lease attempt. 2. Cancellable signal tracking. McpCacheContext stores the cancel id returned by signaler.signalAt in a per-signalId slot, and detach cancels all pending signals before tearing down the lifecycle stream. The defensive detached checks at beginLifecycle and onRefresh entry points (signal targets) are gone — cancellation makes them dead code. Store-callback boundaries (acquire complete handlers) still need detached checks because store ops are not cancellable. 3. Lifecycle stream owns list streams. McpHydrateLifecycleStream tracks active McpListHydrateStream instances via a List; list streams register on construction and unregister on terminal. The three close paths (onLifecycleEnd / onLifecycleAbort / onLifecycleReset) and doLifecycleEnd all call cleanupListStreams to cascade an END to in-flight list streams. Matches the parent-owns-children pattern used by McpLifecycleServer for its McpLifecycleClient children in McpProxyLifecycleFactory. McpListHydrater and McpListHydrateStream drop their private modifiers so the lifecycle stream and context can reference these types directly across the nested class boundary. --- .../mcp/internal/stream/McpCacheContext.java | 66 ++++++++++++++----- .../stream/McpProxyCacheHydrater.java | 54 ++++++++++++--- 2 files changed, 94 insertions(+), 26 deletions(-) diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpCacheContext.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpCacheContext.java index eac9e829d7..ce02c741bb 100644 --- a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpCacheContext.java +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpCacheContext.java @@ -15,13 +15,17 @@ package io.aklivity.zilla.runtime.binding.mcp.internal.stream;

charset=UTF-8 Content-Transfer-Encoding: 8bit Readiness now derives from cache state rather than an explicit populated/expected counter. McpListCache tracks a populated flag that flips on get (re-evaluated each call: true when value non-null, false otherwise) and on put (always true). Both callbacks fire McpCacheContext checkReady which walks the active-cache list (built at start from hydrater.activeCaches) and calls markComplete when all are populated. Awaiters wait for actual cache population rather than the prior optimistic-on-acquire-fail signal — honest readiness. Strategies drop their explicit markReady calls; readiness flows from cache state. initiate (initial entry + contention poll) does cache.get first; refresh (periodic, cacheTtl-paced) does cache.acquire first to force a fresh hydrate. onRefresh dispatches between the two based on backoff state — non-zero backoff means we are in polling mode after losing a recent acquire race. scheduleBackoffRetry doubles the delay from leaseRetry on each acquire-fail, capped at leaseTtl. Reset to zero on successful hydrate or cache-hit. Polling sequence at defaults (leaseRetry=100ms, leaseTtl=30s): 100ms, 300ms, 700ms, 1.5s, 3.1s, 6.3s, 12.7s, 25.5s, cap thereafter. Bounded above by leaseTtl because per-kind lock expires at that point and our acquire must succeed. McpProxyCacheHydrater.refresh gains a polling flag; activeCaches accessor returns the filter-active per-kind cache list for the context. --- .../mcp/internal/stream/McpCacheContext.java | 94 ++++++++++++++----- .../stream/McpProxyCacheHydrater.java | 65 ++++++------- 2 files changed, 100 insertions(+), 59 deletions(-) diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpCacheContext.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpCacheContext.java index ce02c741bb..69fa92ec60 100644 --- a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpCacheContext.java +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpCacheContext.java @@ -64,12 +64,12 @@ public final class McpCacheContext private final McpListCache prompts;

The intermediate StoreHandler variable goes away. - McpProxyCacheHydrater lifecycle stream: drop the if (!McpState.replyClosed(state)) and !initialClosed guards from onLifecycleEnd / onLifecycleAbort / onLifecycleReset. The engine does not deliver an END / ABORT / RESET frame on a direction already closed, so the guards are dead code per the canonical pattern (only do* outbound senders need state guards). --- .../mcp/internal/config/McpBindingConfig.java | 30 +++++++++------ .../mcp/internal/stream/McpCacheContext.java | 32 ++++++++-------- .../mcp/internal/stream/McpClientFactory.java | 2 +- .../stream/McpProxyCacheHydrater.java | 37 +++++++------------ .../mcp/internal/stream/McpServerFactory.java | 2 +- 5 files changed, 51 insertions(+), 52 deletions(-) diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java index 5562da8632..04e1f509d0 100644 --- a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java @@ -35,7 +35,6 @@ import io.aklivity.zilla.runtime.engine.EngineContext;

McpProxyLifecycleFactory now calls binding.cache.register() against the cache directly, not a Manager indirection. The Manager owns refresh, per-kind retry, and lifecycle-reconnect timing; the Handler owns the lifecycle stream plus per-kind state machines and escalates via listener.onError(kind) for stream failures and listener.onClosed() for lifecycle loss. On lifecycle loss the Manager pre-emptively purges each kind so awaiters arriving during the outage wait rather than see stale data, then schedules a backoff reconnect. McpProxyFactory holds a Long2ObjectHashMap of managers keyed by bindingId, mirroring McpServerFactory.sessions, and creates per-binding Managers via Manager.Factory which hides the per-worker hydrater. https://claude.ai/code/session_01WNsipAt3RGwQoeFYVxwfL8 --- .../mcp/internal/config/McpBindingConfig.java | 17 +- .../mcp/internal/stream/McpProxyFactory.java | 20 +- .../internal/stream/McpProxyListFactory.java | 9 +- .../stream/McpProxyPromptsListFactory.java | 3 +- .../stream/McpProxyResourcesListFactory.java | 3 +- .../stream/McpProxyToolsListFactory.java | 3 +- .../mcp/internal/stream/McpSignalHandle.java | 4 +- .../binding/mcp/internal/stream/McpState.java | 34 +- .../McpProxyCache.java} | 246 +++-------- .../stream/cache/McpProxyCacheHandler.java | 25 ++ .../{ => cache}/McpProxyCacheHydrater.java | 414 ++++++++++++------ .../stream/cache/McpProxyCacheListener.java | 23 + .../stream/cache/McpProxyCacheManager.java | 253 +++++++++++ 13 files changed, 687 insertions(+), 367 deletions(-) rename runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/{McpCacheContext.java => cache/McpProxyCache.java} (54%) create mode 100644 runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/cache/McpProxyCacheHandler.java rename runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/{ => cache}/McpProxyCacheHydrater.java (66%) create mode 100644 runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/cache/McpProxyCacheListener.java create mode 100644 runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/cache/McpProxyCacheManager.java diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java index 1b5ab2ff5e..3e970c0d74 100644 --- a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/config/McpBindingConfig.java @@ -26,8 +26,7 @@ import io.aklivity.zilla.runtime.binding.mcp.config.McpOptionsConfig;

The third tools-list arrives within ~100ms, succeeds, and re-populates the cache. - shouldServeLifecycleAfterAwaiterQueued: a north MCP client connects while the binding's hydrate is in flight, so the awaiter registers on cache.populated=false and is queued. After the upstream completes the tools-list hydrate the cache transitions to populated, the awaiter fires, and the client receives its lifecycle BEGIN reply. Also fixes a regression in the Handler/Manager split where the lifecycle lock was no longer released on the populated transition (today's markComplete behaviour). Without this fix, multi-worker engines would have one worker hold the lock indefinitely and starve every other worker's awaiters. McpProxyCacheManager.onCacheReady now calls cache.releaseLifecycle exactly as McpCacheContext.markComplete did before the refactor. https://claude.ai/code/session_01WNsipAt3RGwQoeFYVxwfL8 --- .../stream/cache/McpProxyCacheManager.java | 1 + .../stream/McpProxyCacheToolsListIT.java | 21 ++++ .../client.rpt | 97 +++++++++++++++++++ .../server.rpt | 93 ++++++++++++++++++ .../client.rpt | 36 +++++++ .../server.rpt | 61 ++++++++++++ .../streams/cache/ProxyCacheToolsListIT.java | 9 ++ 7 files changed, 318 insertions(+) create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.refresh.tools.error.retry/client.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.refresh.tools.error.retry/server.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.serve.tools.list.during.hydrate/client.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.serve.tools.list.during.hydrate/server.rpt diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/cache/McpProxyCacheManager.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/cache/McpProxyCacheManager.java index 1b4c578180..aea802b0ee 100644 --- a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/cache/McpProxyCacheManager.java +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/cache/McpProxyCacheManager.java @@ -131,6 +131,7 @@ private void onCacheReady() { return; } + cache.releaseLifecycle(k -> {}); Arrays.fill(kindBackoffMs, 0L); sessionBackoffMs = 0L; scheduleRefresh(); diff --git a/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCacheToolsListIT.java b/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCacheToolsListIT.java index 4aabcc2a50..da5c224ebc 100644 --- a/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCacheToolsListIT.java +++ b/runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCacheToolsListIT.java @@ -83,6 +83,27 @@ public void shouldRefreshToolsError() throws Exception k3po.finish(); } + @Test + @Configuration("proxy.cache.refresh.yaml") + @Specification({ + "${app}/cache.refresh.tools.error.retry/server" }) + @ScriptProperty("serverAddress \"zilla://streams/app1\"") + public void shouldRetryAfterToolsRefreshError() throws Exception + { + k3po.finish(); + } + + @Test + @Configuration("proxy.cache.yaml") + @Specification({ + "${app}/cache.serve.tools.list.during.hydrate/server", + "${app}/cache.serve.tools.list.during.hydrate/client" }) + @ScriptProperty("serverAddress \"zilla://streams/app1\"") + public void shouldServeLifecycleAfterAwaiterQueued() throws Exception + { + k3po.finish(); + } + public static String sessionId() { return "hydrate-1"; diff --git a/specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.refresh.tools.error.retry/client.rpt b/specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.refresh.tools.error.retry/client.rpt new file mode 100644 index 0000000000..7f7c73352e --- /dev/null +++ b/specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.refresh.tools.error.retry/client.rpt @@ -0,0 +1,97 @@ +# +# Copyright 2021-2024 Aklivity Inc +# +# Licensed under the Aklivity Community License (the "License"); you may not use +# this file except in compliance with the License.

The cache hydrate session and any other lifecycle proxy session therefore never observed upstream shutdowns. Adds the matching server.doServer call after the remove. * Server to clients (1-to-many, downward): the shared cleanup() helper always issued doClientEnd to every client regardless of how the server-side terminated, so a north ABORT or RESET was downgraded to a graceful END for every upstream, losing the failure signal. Inlines the fan-out into each onServer with the matching doClient; cleanup() is removed. Adds the missing doServerReset on McpLifecycleServer (mirror of doServerAbort but on the initial side). The cache.hydrate.lifecycle.reconnect IT scenario from the previous WIP commit is rolled back here pending a follow-up design decision on whether McpProxyCache.onPurged should also invalidate the per-kind store data so a reconnect triggers a fresh upstream hydrate cycle (and thus a new lifecycle BEGIN to the exit binding observable in the script). With this commit alone, the cache reconnects internally but no new traffic reaches the exit binding because the store has cached data and McpListHydrater.initiate's get-first path returns it without opening a new list stream. https://claude.ai/code/session_01WNsipAt3RGwQoeFYVxwfL8 --- .../stream/McpProxyLifecycleFactory.java | 45 +++++-- .../stream/McpProxyCacheLifecycleIT.java | 10 -- .../client.rpt | 127 ------------------ .../server.rpt | 124 ----------------- .../streams/cache/ProxyCacheLifecycleIT.java | 9 -- 5 files changed, 32 insertions(+), 283 deletions(-) delete mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.hydrate.lifecycle.reconnect/client.rpt delete mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.hydrate.lifecycle.reconnect/server.rpt diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyLifecycleFactory.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyLifecycleFactory.java index a24bbcc04d..c755c742a2 100644 --- a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyLifecycleFactory.java +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyLifecycleFactory.java @@ -317,7 +317,12 @@ private void onServerEnd( state = McpState.closedInitial(state);

Each scenario opens the lifecycle stream from north (client.rpt to app0) and a tools-list to force the proxy to lazily open its client leg to app1 via supplyClient. After the tools-list completes, the terminal event happens on the lifecycle stream. The 6 scenarios cover both directions of every fix path: * lifecycle.server.write.abort - proxy doServerAbort on reply * lifecycle.server.write.close - proxy doServerEnd on reply * lifecycle.server.read.abort - proxy onServerAbort on initial * lifecycle.client.write.abort - proxy doClientAbort on initial * lifecycle.client.write.close - proxy doClientEnd on initial * lifecycle.client.read.abort - proxy onClientAbort on reply Pairs cover the same end-to-end flow from opposite observation points (server.write.abort <-> client.read.abort for upward ABORT; server.read.abort <-> client.write.abort for downward ABORT). END is asymmetric: server.write.close locks down upward END, client.write.close locks down downward END. Binding-side IT: new McpProxyLifecycleIT class, no cache config.

McpProxyCache.populated flag drops to package-private so the hydrate strategy can read it. checkReady fires onReady on every aggregate populated state (not just on the false to true transition), so the Manager's refresh schedule is renewed each time a kind's value is overwritten via cache.put. Manager.onClosed stops calling cache.onPurged; the cached value stays visible across the reconnect. McpListHydrater.initiate now picks get-first vs acquire-direct based on cache.populated. On the initial cycle (cache empty) it stays get-first to coordinate across workers/nodes that may have populated the same key. Once populated, it goes acquire-direct: we are the cache trying to pull a fresher value into ourselves, so get-first would short-circuit on our own cached value and never refresh. refresh stays acquire-direct unconditionally. The Gap 1 spec scripts cache.hydrate.lifecycle.reconnect/{client,server} exercise the full cycle: 4 streams on app1 for the initial hydrate, an abort on the lifecycle reply once all kinds populate, then 4 fresh streams on app1 with new payloads after the proxy reconnects. The binding-side IT shouldReconnectAfterLifecycleAbort uses just server.rpt with proxy.cache.yaml (no override).

Four spec-side ProxyCache*IT classes collapse similarly into ProxyCacheIT alongside ApplicationIT / NetworkIT. The per-IT-class MCP_HYDRATE_FILTER override is replaced by per-test @Configure(name = MCP_HYDRATE_FILTER_NAME, value = "tools") (or "resources" / "prompts"). Default in the class-wide engine rule is the unfiltered all-kinds predicate. The contention test additionally pins ENGINE_WORKERS=2 and uses a rotating session-id supplier, both via @Configure. McpConfiguration.decodeHydrateFilter now accepts a space-separated list of kind names ("tools", "resources", "prompts") instead of a method reference. Each name maps to its KIND_*_LIST constant, and the resulting Set is exposed as an IntPredicate via Set::contains. Drops the reflective findStatic lookup and the per-IT-class hydrate*Only static helpers. https://claude.ai/code/session_01WNsipAt3RGwQoeFYVxwfL8 --- .../mcp/internal/McpConfiguration.java | 37 +-- .../stream/McpProxyCacheContentionIT.java | 83 ------ .../mcp/internal/stream/McpProxyCacheIT.java | 239 ++++++++++++++++++ .../stream/McpProxyCacheLifecycleIT.java | 115 --------- .../stream/McpProxyCachePromptsListIT.java | 86 ------- .../stream/McpProxyCacheResourcesListIT.java | 86 ------- .../stream/McpProxyCacheToolsListIT.java | 116 --------- ...acheLifecycleIT.java => ProxyCacheIT.java} | 83 +++++- .../cache/ProxyCachePromptsListIT.java | 56 ---- .../cache/ProxyCacheResourcesListIT.java | 56 ---- .../streams/cache/ProxyCacheToolsListIT.java | 83 ------ 11 files changed, 343 insertions(+), 697 deletions(-) delete mode 100644 runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCacheContentionIT.java create mode 100644 runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCacheIT.java delete mode 100644 runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCacheLifecycleIT.java delete mode 100644 runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCachePromptsListIT.java delete mode 100644 runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCacheResourcesListIT.java delete mode 100644 runtime/binding-mcp/src/test/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyCacheToolsListIT.java rename specs/binding-mcp.spec/src/test/java/io/aklivity/zilla/specs/binding/mcp/streams/cache/{ProxyCacheLifecycleIT.java => ProxyCacheIT.java} (56%) delete mode 100644 specs/binding-mcp.spec/src/test/java/io/aklivity/zilla/specs/binding/mcp/streams/cache/ProxyCachePromptsListIT.java delete mode 100644 specs/binding-mcp.spec/src/test/java/io/aklivity/zilla/specs/binding/mcp/streams/cache/ProxyCacheResourcesListIT.java delete mode 100644 specs/binding-mcp.spec/src/test/java/io/aklivity/zilla/specs/binding/mcp/streams/cache/ProxyCacheToolsListIT.java diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/McpConfiguration.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/McpConfiguration.java index 457e1057d8..4e2e1f54fa 100644 --- a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/McpConfiguration.java +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/McpConfiguration.java @@ -14,6 +14,9 @@ */ package io.aklivity.zilla.runtime.binding.mcp.internal;

The list factories look up via cache.cacheOf(kind), and McpProxyCacheManager iterates cache.caches().keySet() rather than holding its own active-kinds projection. McpProxyCacheHydrater stores its kind-to-strategy mapping in an Int2ObjectHashMap, replacing the switch in hydraterOf. HandlerImpl no longer owns per-kind backoff state, per-kind retry signals, or lifecycle-acquire retry signals; on per-kind acquire/stream error it escalates via listener.onError(kind), and on lifecycle-acquire failure it escalates via listener.onClosed(). All retry timing (per-kind retry, refresh cadence, lifecycle reconnect) now lives in Manager. McpProxyCacheListener gains onOpened() so the Manager can dispatch initial per-kind hydrate immediately after the lifecycle stream opens; McpProxyCacheManager registers cache.onReady as today. McpProxyCache no longer holds a Signaler reference. Awaiters are registered as plain Runnable; McpProxyLifecycleFactory captures a Signaler at construction and calls signaler.signalNow(...) directly from the registered lambda. McpSignalHandle is removed. The lifecycle stream and list-hydrate streams cache originId/routedId fields (both equal to cache.bindingId), use them throughout. The lifecycle stream's child-stream registry is renamed streams. The lock-key constant is renamed STORE_LOCK_KEY_LIFECYCLE for symmetry with the other lock keys. McpListHydrater.hydrate retains the cache.populated branch -- get-first on initial dispatch (to read through seeded data without opening a list stream) and acquire-direct once populated (so refresh actually overwrites). https://claude.ai/code/session_01WNsipAt3RGwQoeFYVxwfL8 --- .../stream/McpProxyLifecycleFactory.java | 7 +- .../stream/McpProxyPromptsListFactory.java | 4 +- .../stream/McpProxyResourcesListFactory.java | 4 +- .../stream/McpProxyToolsListFactory.java | 4 +- .../mcp/internal/stream/McpSignalHandle.java | 31 -- .../internal/stream/cache/McpProxyCache.java | 92 +++--- .../stream/cache/McpProxyCacheHydrater.java | 281 +++++------------- .../stream/cache/McpProxyCacheListener.java | 2 + .../stream/cache/McpProxyCacheManager.java | 88 +++--- 9 files changed, 169 insertions(+), 344 deletions(-) delete mode 100644 runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpSignalHandle.java diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyLifecycleFactory.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyLifecycleFactory.java index c755c742a2..9790ce403d 100644 --- a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyLifecycleFactory.java +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyLifecycleFactory.java @@ -44,6 +44,7 @@ import io.aklivity.zilla.runtime.engine.EngineContext; import io.aklivity.zilla.runtime.engine.binding.BindingHandler; import io.aklivity.zilla.runtime.engine.binding.function.MessageConsumer; +import io.aklivity.zilla.runtime.engine.concurrent.Signaler; final class McpProxyLifecycleFactory implements BindingHandler { @@ -77,6 +78,7 @@ final class McpProxyLifecycleFactory implements BindingHandler private final MutableDirectBuffer writeBuffer; private final MutableDirectBuffer codecBuffer; private final BindingHandler streamFactory; + private final Signaler signaler; private final LongUnaryOperator supplyInitialId; private final LongUnaryOperator supplyReplyId; private final int mcpTypeId; @@ -90,6 +92,7 @@ final class McpProxyLifecycleFactory implements BindingHandler this.writeBuffer = context.writeBuffer(); this.codecBuffer = new UnsafeBuffer(new byte[context.writeBuffer().capacity()]); this.streamFactory = context.streamFactory(); + this.signaler = context.signaler(); this.supplyInitialId = context::supplyInitialId; this.supplyReplyId = context::supplyReplyId; this.mcpTypeId = context.supplyTypeId(MCP_TYPE_NAME); @@ -265,8 +268,8 @@ private void onServerBegin( if (binding.cache != null && originId != routedId) { - binding.cache.register( - new McpSignalHandle(originId, routedId, replyId, traceId, SIGNAL_HYDRATE_COMPLETE)); + binding.cache.register(() -> signaler.signalNow( + originId, routedId, replyId, traceId, SIGNAL_HYDRATE_COMPLETE, 0)); } else { diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyPromptsListFactory.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyPromptsListFactory.java index 3146fca275..da0c321778 100644 --- a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyPromptsListFactory.java +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyPromptsListFactory.java @@ -14,6 +14,8 @@ */ package io.aklivity.zilla.runtime.binding.mcp.internal.stream; +import static io.aklivity.zilla.runtime.binding.mcp.internal.types.stream.McpBeginExFW.KIND_PROMPTS_LIST; + import java.nio.charset.StandardCharsets; import java.util.List; import java.util.function.LongFunction; @@ -46,7 +48,7 @@ final class McpProxyPromptsListFactory extends McpProxyListFactory protected McpProxyCache.McpListCache cacheOf( McpBindingConfig binding) { - return binding.cache != null ?

Int2ObjectHashMap iteration order is hash-bucket order, not insertion order, but it is deterministic for a fixed set of int keys at a fixed initial capacity. With KIND_TOOLS_LIST / KIND_RESOURCES_LIST / KIND_PROMPTS_LIST the dispatch order is prompts -> tools -> resources; update every multi-kind cache.hydrate* spec script (both server.rpt and client.rpt sides) to that order so peer-to-peer ProxyCacheIT and the binding-side McpProxyCacheIT both pass. cache.hydrate, cache.hydrate.credentials, cache.hydrate.error, cache.hydrate.toolkit, cache.hydrate.lifecycle.reconnect all reorder their three accepted blocks (or the corresponding chain of client connects via barriers) from tools/resources/prompts to prompts/tools/resources. cache.hydrate.error keeps tools as the kind that aborts (now second in the chain rather than first). The lifecycle-reconnect script moves the write-notify ALL_HYDRATED to the new last block (resources) on both cycles. The toolkit script applies the reorder to both the app1 and app2 cycles. https://claude.ai/code/session_01WNsipAt3RGwQoeFYVxwfL8 --- .../internal/stream/cache/McpProxyCache.java | 10 ++--- .../cache.hydrate.credentials/client.rpt | 20 ++++----- .../cache.hydrate.credentials/server.rpt | 12 ++--- .../cache.hydrate.error/client.rpt | 22 +++++----- .../cache.hydrate.error/server.rpt | 26 +++++------ .../client.rpt | 40 ++++++++--------- .../server.rpt | 24 +++++----- .../cache.hydrate.toolkit/client.rpt | 44 +++++++++---------- .../cache.hydrate.toolkit/server.rpt | 24 +++++----- .../application/cache.hydrate/client.rpt | 20 ++++----- .../application/cache.hydrate/server.rpt | 12 ++--- 11 files changed, 127 insertions(+), 127 deletions(-) diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/cache/McpProxyCache.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/cache/McpProxyCache.java index aa10e60f96..dd47bebe1a 100644 --- a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/cache/McpProxyCache.java +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/cache/McpProxyCache.java @@ -20,14 +20,14 @@ import java.time.Duration; import java.util.ArrayList; -import java.util.LinkedHashMap; import java.util.List; -import java.util.Map; import java.util.Optional; import java.util.function.BiConsumer; import java.util.function.Consumer; import java.util.function.IntPredicate; +import org.agrona.collections.Int2ObjectHashMap; + import io.aklivity.zilla.runtime.binding.mcp.config.McpCacheConfig; import io.aklivity.zilla.runtime.binding.mcp.internal.McpConfiguration; import io.aklivity.zilla.runtime.engine.EngineContext; @@ -59,7 +59,7 @@ public final class McpProxyCache public long authorization; private final StoreHandler store; -

Replace with a Function captured as a method reference (Factory::create) so the attach call site reads supplyManager.apply(cache) and the factory class no longer leaks the nested Factory type into its field declarations. https://claude.ai/code/session_01WNsipAt3RGwQoeFYVxwfL8 --- .../binding/mcp/internal/stream/McpProxyFactory.java | 9 ++++++--- 1 file changed, 6 insertions(+), 3 deletions(-) diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyFactory.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyFactory.java index ce9adb01b3..0223ed09f8 100644 --- a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyFactory.java +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/McpProxyFactory.java @@ -22,12 +22,15 @@ import static io.aklivity.zilla.runtime.binding.mcp.internal.types.stream.McpBeginExFW.KIND_TOOLS_CALL; import static io.aklivity.zilla.runtime.binding.mcp.internal.types.stream.McpBeginExFW.KIND_TOOLS_LIST; +import java.util.function.Function; + import org.agrona.DirectBuffer; import org.agrona.collections.Int2ObjectHashMap; import org.agrona.collections.Long2ObjectHashMap; import io.aklivity.zilla.runtime.binding.mcp.internal.McpConfiguration; import io.aklivity.zilla.runtime.binding.mcp.internal.config.McpBindingConfig; +import io.aklivity.zilla.runtime.binding.mcp.internal.stream.cache.McpProxyCache; import io.aklivity.zilla.runtime.binding.mcp.internal.stream.cache.McpProxyCacheManager; import io.aklivity.zilla.runtime.binding.mcp.internal.types.OctetsFW; import io.aklivity.zilla.runtime.binding.mcp.internal.types.stream.BeginFW; @@ -51,7 +54,7 @@ public final class McpProxyFactory implements McpStreamFactory private final Long2ObjectHashMap bindings; private final Long2ObjectHashMap managers; private final Int2ObjectHashMap factories; - private final McpProxyCacheManager.Factory cacheManagers; + private final Function supplyManager; public McpProxyFactory( McpConfiguration config, @@ -62,7 +65,7 @@ public McpProxyFactory( this.bindings = new Long2ObjectHashMap<>(); this.managers = new Long2ObjectHashMap<>(); this.factories = new Int2ObjectHashMap<>(); - this.cacheManagers = new McpProxyCacheManager.Factory(config, context); + this.supplyManager = new McpProxyCacheManager.Factory(config, context)::create; this.factories.put(KIND_LIFECYCLE, new McpProxyLifecycleFactory(config, context, bindings::get)); this.factories.put(KIND_TOOLS_CALL, @@ -94,7 +97,7 @@ public void attach( bindings.put(binding.id, newBinding); if (newBinding.cache != null) { - McpProxyCacheManager manager = cacheManagers.create(newBinding.cache); + McpProxyCacheManager manager = supplyManager.apply(newBinding.cache); managers.put(binding.id, manager); manager.start(); } From 6e98cdb0b9f87f48eda366204fb240db58ed31d2 Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 21 May 2026 06:22:02 +0000 Subject: [PATCH 81/83] test(binding-mcp): cover hydrate and serve at 10k and 100k payloads Add shouldHydrate10k, shouldHydrate100k, shouldServeToolsList10k, and shouldServeToolsList100k to McpProxyCacheIT, each pinning the engine buffer slot capacity to 8192 so the payloads cross the slot boundary. The 10k variant uses core:randomBase64(10000) for ~13KB of body; the 100k variant uses core:randomBase64(100000) for ~133KB. The seeded yaml for the serve variants references the new randomBase64 template handled by TestResolverSpi -- e.g. '{"tools":[{"name":"big_tool","description":"${{test.randomBase64.10000}}"}]}' -- so the config stays compact while the resolver expands the template at config-load time to the same deterministic Base64 string that core:randomBase64 produces inside the .rpt scripts. McpListHydrateStream was missing the receive-side flow-control update: onListHydrateBegin now seeds replySeq/replyAck from the begin frame, and onListHydrateData advances replySeq by data.reserved() and acks replyAck = replySeq before re-emitting WINDOW. Without this, upstream stalled once its in-flight reached replyMax (= slotCapacity) for any single list-hydrate payload larger than one slot. https://claude.ai/code/session_01WNsipAt3RGwQoeFYVxwfL8 --- .../stream/cache/McpProxyCacheHydrater.java | 6 ++ .../mcp/internal/stream/McpProxyCacheIT.java | 45 ++++++++ .../internal/resolver/TestResolverSpi.java | 12 +++ .../config/proxy.cache.seeded.tools.100k.yaml | 36 +++++++ .../config/proxy.cache.seeded.tools.10k.yaml | 36 +++++++ .../application/cache.hydrate.100k/client.rpt | 99 +++++++++++++++++ .../application/cache.hydrate.100k/server.rpt | 101 ++++++++++++++++++ .../application/cache.hydrate.10k/client.rpt | 99 +++++++++++++++++ .../application/cache.hydrate.10k/server.rpt | 101 ++++++++++++++++++ .../cache.serve.tools.list.100k/client.rpt | 57 ++++++++++ .../cache.serve.tools.list.100k/server.rpt | 62 +++++++++++ .../cache.serve.tools.list.10k/client.rpt | 57 ++++++++++ .../cache.serve.tools.list.10k/server.rpt | 62 +++++++++++ .../mcp/streams/cache/ProxyCacheIT.java | 36 +++++++ 14 files changed, 809 insertions(+) create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/config/proxy.cache.seeded.tools.100k.yaml create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/config/proxy.cache.seeded.tools.10k.yaml create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.hydrate.100k/client.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.hydrate.100k/server.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.hydrate.10k/client.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.hydrate.10k/server.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.serve.tools.list.100k/client.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.serve.tools.list.100k/server.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.serve.tools.list.10k/client.rpt create mode 100644 specs/binding-mcp.spec/src/main/scripts/io/aklivity/zilla/specs/binding/mcp/streams/application/cache.serve.tools.list.10k/server.rpt diff --git a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/cache/McpProxyCacheHydrater.java b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/cache/McpProxyCacheHydrater.java index 68dfe60f19..8af2e824dd 100644 --- a/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/cache/McpProxyCacheHydrater.java +++ b/runtime/binding-mcp/src/main/java/io/aklivity/zilla/runtime/binding/mcp/internal/stream/cache/McpProxyCacheHydrater.java @@ -510,6 +510,8 @@ private void onListHydrateMessage( private void onListHydrateBegin( BeginFW begin) { + replySeq = begin.sequence();
