Upstream tool calls are counted as a single bucketed total (`0` / `1-10` / `11-100` / `101-1000` / `1000+`); upstream tool *names* are never recorded. +3. **REST endpoint histogram** keyed by Chi route templates (e.g., `POST /api/v1/servers/{name}/enable`) and status classes (`2xx` / `4xx` / `5xx`). Unmatched routes are bucketed under the literal key `UNMATCHED`. Path parameters are never included. +4. **Feature-flag adoption matrix** — boolean snapshot of `enable_socket`, `enable_prompts`, `require_mcp_auth`, `enable_code_execution`, `quarantine_enabled`, `sensitive_data_detection_enabled`, plus a sorted/deduped list of OAuth provider *types* (`google` / `github` / `microsoft` / `generic`) derived from upstream URL heuristics. +5. **Startup outcome** — one of `success` / `port_conflict` / `db_locked` / `config_error` / `permission_error` / `other_error`, persisted to config and reported in the next heartbeat. Mapped from the existing `classifyError()` → exit code taxonomy. +6. **Upgrade funnel** — persistent `last_reported_version` in config. Each heartbeat reports `previous_version` → `current_version`. Advanced only on a successful 2xx send; failures preserve the cursor for retry. +7. **Error category histogram** — fixed 11-value `ErrorCategory` enum. Wired at three real error sites: `EmitOAuthRefreshFailed` → `oauth_refresh_failed`, `EmitActivityPolicyDecision` (when decision is `blocked`) → `tool_quarantine_blocked`, and `EmitActivityToolCallCompleted` (classifies error *messages* by keyword → `upstream_connect_timeout` / `upstream_connect_refused` / `upstream_handshake_failed` — only the enum name is ever recorded, never the message). +8. **Annual anonymous-ID rotation** — persistent `anonymous_id_created_at` timestamp; rotation on next heartbeat render when >365 days old; legacy installs get `created_at` initialized without rotating; clock skew and corrupt timestamps handled defensively. +9. **Doctor check pass/fail rates** — synthesized from `contracts.Diagnostics` into a fixed set of named checks (`upstream_connections`, `oauth_required`, `oauth_issues`, `missing_secrets`, `runtime_warnings`, `deprecated_configs`, `docker_status`). Called from the `/api/v1/diagnostics` REST handler so the aggregation happens on the daemon side, not ephemeral CLI clients. +10. **`DO_NOT_TRACK` and `CI` env var honor** — new `IsDisabledByEnv()` with precedence `DO_NOT_TRACK > CI > MCPPROXY_TELEMETRY=false > config`. Checked once at `telemetry.New()` construction and visible in `mcpproxy telemetry status` output. +11. **`mcpproxy telemetry show-payload` CLI command** — renders the exact JSON that would next be sent to the telemetry endpoint, with all Tier 2 fields populated from current in-memory counters. Makes no network call. Works even when telemetry is disabled. +12. **First-run notice** — one-time banner printed to stderr on first `mcpproxy serve` invocation, persisted via `telemetry.notice_shown=true`. Skipped automatically when telemetry is already disabled (by config or env) so users who opt out never see nagging. + +## Speckit workflow + +Executed in strict sequence via the speckit skills: + +1. **`/speckit.specify`** — wrote `spec.md` with 10 user stories (P1-P3), 44 functional requirements, privacy constraints, success criteria, out-of-scope, and a 15-item Assumptions section. Zero `[NEEDS CLARIFICATION]` markers per the autonomous override. +2. **`/speckit.plan`** — wrote `plan.md` with technical context, constitution gate evaluation (one justified violation in Complexity Tracking: `sync.RWMutex` instead of an actor), and project structure. Generated `research.md` resolving 16 technical unknowns, `data-model.md` with all entities and invariants, `contracts/heartbeat-v2.schema.json` as the JSON schema, and `quickstart.md`. +3. **`/speckit.tasks`** — wrote `tasks.md` with 91 dependency-ordered sub-tasks across 13 phases, each ≤ 2h. +4. **Implementation** — executed phases 1-13 in-session: + - Phase 1: read-only exploration of integration points. + - Phase 2 (foundation): `CounterRegistry`, `ErrorCategory`, `IsDisabledByEnv`, extended `HeartbeatPayload`, `TelemetryConfig` fields. + - Phases 3-11 (user stories): surface middleware, MCP tool counters, REST endpoint histogram, feature flags, startup outcome, error categories, upgrade funnel, ID rotation, doctor wiring, show-payload + first-run notice. + - Phase 13 (polish): privacy substring test, lint fix (dropped deprecated `EnableTray`), build verification, env-override status display. + +## Test results + +### Unit tests (`-race`) + +- `internal/telemetry/...` — **PASS** (all 14 test files, including `registry_test.go`, `payload_v2_test.go`, `id_rotation_test.go`, `payload_privacy_test.go`, `feature_flags_test.go`, `env_overrides_test.go`, `error_categories_test.go`, `notice_test.go`) +- `internal/httpapi/...` — **PASS** (including new `middleware_telemetry_test.go` covering surface classifier and REST endpoint histogram) +- `internal/cliclient/...` — **PASS** (including new `header_test.go` asserting `X-MCPProxy-Client: cli/` on outbound requests) +- `internal/server/...` subset (`TestHandleUpstream*`, `TestHandleCallTool*`, `TestHandleRetrieveTools*`, `TestHandleQuarantine*`) — **PASS** in ~14s +- `cmd/mcpproxy/...` — **PASS** (including new `startup_outcome_test.go`) +- Full package `internal/server/...` with race — times out at 600s/1500s/300s (pre-existing scale issue: >120 E2E/binary tests with race detection; individual tests pass in isolation, confirmed on `main` branch too). -## Architecture Decisions +### Linter -| Decision | Choice | Rationale | -|----------|--------|-----------| -| UI framework | SwiftUI MenuBarExtra + AppKit escape hatches | Declarative for 80%, AppKit for custom views | -| Core communication | Unix socket via custom URLProtocol | Matches existing Go tray, no API key needed | -| State updates | SSE via URLSession.bytes + AsyncStream | Real-time, existing /events endpoint | -| Auto-update | Sparkle 2.x via SPM | macOS standard, EdDSA signing, GitHub Releases | -| Login item | SMAppService (macOS 13+) | Apple's modern API | -| Notifications | UNUserNotificationCenter + categories | Actionable buttons, rate-limited | -| Process management | Foundation Process + DispatchSource | Native Swift, zero dependencies | -| Target | macOS 13 Ventura+ | MenuBarExtra, SMAppService availability | +- `./scripts/run-linter.sh` — **0 issues**. -## Scope Boundary (3-spec series) +### Builds -| Spec | Scope | Status | -|------|-------|--------| -| **A (this)** | Tray menu + core management + notifications + auto-update | IMPLEMENTED | -| **B (future)** | Main app window: servers, activity log, secrets, config views | NOT STARTED | -| **C (future)** | MCP accessibility testing server (Swift) | NOT STARTED | +- `go build ./cmd/mcpproxy` (personal edition) — **PASS** +- `go build -tags server ./cmd/mcpproxy` (server edition) — **PASS** -## Commits +### Manual verification + +- `./mcpproxy telemetry show-payload` on a real config — **PASS**: emits `schema_version: 2`, `anonymous_id_created_at` (auto-initialized for legacy install), all counter maps zeroed, `feature_flags` populated from config, no network call. +- `DO_NOT_TRACK=1 ./mcpproxy telemetry status` — **PASS**: reports `Status: Disabled`, `Override: DO_NOT_TRACK`. +- `./mcpproxy telemetry --help` — **PASS**: shows the new `show-payload` subcommand. + +### E2E API test + +- `./scripts/test-api-e2e.sh` — 61 pass, 10 fail. **All 10 failures are pre-existing on `main`** (verified by checking out `main` and re-running: same 10 failures, identical test names).
