A single FastMCP server exposes six MCP tools that clone a Git repository, run OpenCode against a task description, scan the result for leaked credentials, push a branch, and open a pull request. Each task runs in an isolated Firecracker microVM; sync and async execution modes are both supported, and the six tools are reachable through any MCP client (Kiro, Claude Desktop, Cursor) by way of an AgentCore Gateway. + +The purpose of the sample is to show how AgentCore's building blocks compose into an end-to-end workload. Runtime hosts the MCP server and manages async task lifecycle and session storage. Gateway fronts the Runtime, authenticates callers via Cognito, and authenticates itself to the Runtime over SigV4. Identity vaults the per-user Git OAuth tokens used by the pipeline. Policy evaluates Cedar rules to gate which tools a caller can invoke against which repositories. Observability flows OTEL metrics through the managed ADOT sidecar into the built-in GenAI dashboard. The section below maps each capability to the code that exercises it. + +## AgentCore Capabilities Demonstrated + +This sample exercises five AgentCore capabilities and deliberately does not use three others.

Each opens with a one-sentence definition, then describes how the capability shows up in this codebase and points at the file(s) that implement it. For the end-to-end request path, see [docs/ARCHITECTURE.md](docs/ARCHITECTURE.md). + +### Runtime + +**Definition.** AgentCore Runtime is a managed compute service that hosts agent code inside per-session Firecracker microVMs and provides session lifecycle, async task scheduling, and durable session storage. + +This sample ships a single FastMCP server in [`container/code_mcp_server.py`](container/code_mcp_server.py) that exposes six MCP tools over Streamable HTTP on port 8000. The Runtime is declared in [`stacks/agentcore_stack.py`](stacks/agentcore_stack.py), which builds the container image, creates the execution role with Bedrock-invoke and Identity-SDK permissions, and (in regions where the CFN schema accepts it) enables managed session storage via `FilesystemConfigurations` so work directories survive microVM stop/resume. + +Long-running coding jobs run through the async task interface. The `run_coding_task` tool calls `add_async_task()`, which registers the job with the Runtime's scheduler and returns a `job_id` immediately; the Runtime surfaces a `HealthyBusy` status to the Gateway while background work progresses, so subsequent requests on the same session know something is already in flight. + +The `cancel_task` tool demonstrates cross-session cancellation. In-process cancellation is tried first, but if the job is running on a different session the tool falls back to the Runtime control-plane `StopRuntimeSession` API, which terminates the worker microVM wherever it happens to be, then records the terminal state in DynamoDB. + +### Gateway + +**Definition.** AgentCore Gateway is a managed MCP front door that authenticates inbound callers, evaluates policy, and forwards MCP calls to one or more registered targets (MCP Server, Lambda, OpenAPI, or Smithy). + +The Gateway is declared in [`stacks/gateway_stack.py`](stacks/gateway_stack.py). Inbound auth is a `CustomJwtAuthorizer` bound to a Cognito user pool; outbound auth to the Runtime uses `GATEWAY_IAM_ROLE` so the Gateway signs forwarded requests with SigV4 instead of reusing the caller's JWT. The target is configured as an MCP Server pointing at the Runtime, so the six tools are discovered dynamically at tool-list time rather than being enumerated in the template. + +Between inbound JWT validation and outbound SigV4 signing, a REQUEST interceptor Lambda runs ([`lambda/interceptor/index.py`](lambda/interceptor/index.py)). Its job is subtle: the Runtime protocol for Streamable HTTP reserves the `Authorization` header for the Gateway's own SigV4 signature, but inbound MCP requests already carry the caller's Cognito bearer token in that header. If both headers coexist downstream, signature validation fails. The interceptor strips the inbound `Authorization` header, decodes the JWT it carried, and injects the caller's `sub` claim into tool arguments as `_user_id` so tools can still attribute work to a user. The deeper rationale lives in [docs/ARCHITECTURE.md#architectural-decisions](docs/ARCHITECTURE.md#architectural-decisions). + +### Identity + +**Definition.** AgentCore Identity is a managed workload-identity and credential-vaulting service that brokers 3-legged OAuth flows on behalf of an agent, returning short-lived access tokens without the agent ever touching the refresh token. + +This sample registers a GitHub OAuth2 credential provider in [`stacks/identity_stack.py`](stacks/identity_stack.py). A workload identity named `opencode_runtime` binds the Runtime's execution role to this provider so `get_token` calls from inside the microVM are authorized by Identity. + +Interactive consent is delivered via the `connect_git_host` MCP tool. When invoked, it calls `ctx.elicit()` to push the provider's authorization URL back to the caller's MCP client, pauses, and resumes once Identity receives the callback. The callback itself is handled by an API Gateway HTTP API fronting [`lambda/oauth_callback/index.py`](lambda/oauth_callback/index.py), which forwards the authorization code to Identity and closes the loop. The async `run_coding_task` pipeline cannot elicit mid-job, so it fails fast with `git_host_not_connected` if credentials for the target host have not been vaulted yet. Token resolution at tool-call time happens in [`container/tools/resolve_git_credential.py`](container/tools/resolve_git_credential.py). + +### Policy + +**Definition.** AgentCore Policy is a Cedar-based policy engine you can attach to a Gateway to evaluate permit/forbid rules on every MCP tool call, either in LOG_ONLY mode (observability) or ENFORCE mode (blocking). + +The Policy Engine is provisioned in [`stacks/policy_stack.py`](stacks/policy_stack.py) and associated with the Gateway in **LOG_ONLY** mode by default. Policies themselves are created post-deploy by [`scripts/create-policies.py`](scripts/create-policies.py) rather than CDK, because the `CfnPolicy` resource handler has a stabilization bug that surfaces as `CREATE_FAILED` even on successful creation. + +Action names follow AgentCore's `{target}___{tool}` convention with three underscores. Because this sample registers a single MCP Server target named `opencode`, the effective action identifiers are `opencode___code`, `opencode___run_coding_task`, `opencode___connect_git_host`, `opencode___get_task_status`, `opencode___list_tasks`, and `opencode___cancel_task`. + +The bundled policies express two axes of control: role-based access (the `readonly` role is forbidden from `opencode___run_coding_task` and `opencode___cancel_task`) and repo-pattern access (a global `forbid` rule for repositories matching `*-production`). Flipping from LOG_ONLY to ENFORCE and adding organization-specific rules is covered in [docs/HARDENING.md#cedar-policy-engine](docs/HARDENING.md#cedar-policy-engine). + +### Observability + +**Definition.** AgentCore Observability is the managed telemetry path that collects OTEL traces, metrics, and logs from every Runtime session via a built-in ADOT sidecar and renders them in a managed GenAI observability dashboard. + +This sample emits OTEL metrics from inside the microVM using the helpers in [`container/lib/metrics.py`](container/lib/metrics.py). The ADOT collector is provided by the AgentCore platform: no sidecar definition or exporter configuration lives in the CDK tree; [`stacks/observability_stack.py`](stacks/observability_stack.py) only declares CloudWatch log groups for the Runtime and the Gateway's interceptor Lambda. + +What shows up in the managed GenAI dashboard without any extra wiring: per-invocation token usage and cost, full request traces across Gateway and Runtime, and per-user traceability (the `_user_id` injected by the interceptor is captured as a span attribute, so every job is attributable to its caller). The sample's custom metrics add job duration and files-edited counts per coding task, which surface alongside the built-in token and latency metrics. + +What is **not** set up: custom CloudWatch dashboards, custom alarms, and AWS Budgets for Bedrock spend. The `daily_cost_budget_usd` value in `cdk.json` is a reference only; see the AWS Budgets section in [docs/HARDENING.md](docs/HARDENING.md) for how to wire real cost alerts. + +## MCP Tools + +Six tools exposed through the AgentCore Gateway via a single MCP Server target named `opencode`. Cold start is roughly 1.2 s per microVM. + +| Tool | Mode | Description | Required parameters | +|------|------|-------------|---------------------| +| `code` | Sync | Execute coding task, stream progress via MCP, return PR URL.

It is not a production-ready product - defaults optimize for cost and clarity. For production use, start with [docs/HARDENING.md](docs/HARDENING.md). + +- **Memory, built-in Tools (Code Interpreter / Browser Tool), and Evaluation capabilities are deliberately not used.** See the capability mapping table above for the rationale. +- **No task-level retries or dead-letter queues.** Failed pipeline steps fail the job immediately. The only exception is `git push`, which has a 3-retry rebase loop for concurrent-push races. +- **Async tasks cannot elicit.** The `run_coding_task` async path cannot pause for OAuth consent mid-job, so users must run `connect_git_host` first. A missing credential surfaces as `git_host_not_connected`. +- **Regional availability.** `us-east-1` and `eu-central-1` are tested. Other AgentCore-supported regions may work but are untested. Managed session storage (`FilesystemConfigurations`) only activates in regions where the CFN schema accepts it. See [docs/HARDENING.md#tested-regions](docs/HARDENING.md#tested-regions). +- **Outbound traffic is not FQDN-restricted.** Git clone and push to any HTTPS host on the public internet are unfiltered via the NAT Gateway. See [docs/HARDENING.md#known-limitations](docs/HARDENING.md#known-limitations). +- **GSI1 admin-monitoring index has a partition cap.** The `status#{status}` GSI has only 4 partition-key values, so at high volume it hits per-partition RCU/WCU limits. See [docs/HARDENING.md#known-limitations](docs/HARDENING.md#known-limitations). +- **Alpha CDK module.** The Gateway stack depends on `aws_cdk.aws_bedrock_agentcore_alpha`. Alpha APIs may break between minor CDK versions; the requirement is pinned with a tight upper bound to catch drift. +- **`CfnPolicy` is managed via a post-deploy script**, not native CDK, because the resource handler reports `NotStabilized` even on successful creation. See [`scripts/create-policies.py`](scripts/create-policies.py). + +## Cleanup + +Several resources (DynamoDB table, S3 bucket, ECR repository, CloudWatch log groups) use a `RETAIN` removal policy so a `cdk destroy` does not silently drop data. The tradeoff is that these resources survive the destroy and can cause "already exists" errors on the next deploy unless you clean them up. + +```bash +cdk destroy --all +./scripts/cleanup-retained-resources.sh +``` + +The cleanup script removes the `opencode-jobs` table, the `opencode-artifacts-*` bucket, the `opencode-agentcore` ECR repository, the `/opencode/*` log groups, and any orphaned networking resources tagged `Project=OpenCode`. AgentCore-managed ENIs can take 5-10 minutes to release after runtime deletion - re-run the script if it reports ENIs still releasing. + +If deployment fails or `cdk destroy` leaves resources behind, see [docs/TROUBLESHOOTING.md](docs/TROUBLESHOOTING.md). + +## Cost considerations + +Base infrastructure cost, with no tasks running, is roughly: + +- VPC interface endpoints: ~$161/month (11 endpoints × 2 AZs at $0.01/endpoint/AZ/hour) +- NAT Gateway: ~$32/month plus data transfer +- KMS CMK: ~$1/month +- DynamoDB, S3, CloudWatch: pay-per-use, negligible at low volume +- AgentCore Runtimes: scale to zero when idle + +Per-task cost is dominated by Bedrock token usage and Firecracker compute time.

This section walks through each component and why it's there. Service names are introduced at first mention: Amazon Bedrock AgentCore (AgentCore), Amazon Virtual Private Cloud (Amazon VPC), Amazon Bedrock, and AWS Key Management Service (AWS KMS); subsequent mentions use the short form. + +### MCP Client -> AgentCore Gateway + +Your MCP client (Kiro, Claude Desktop, Cursor) sends a `tools/call` request to the AgentCore Gateway. The Gateway is a managed MCP endpoint - it handles authentication, authorization, and routing so the container doesn't have to. Inbound requests authenticate via Cognito JWT tokens - the Gateway validates the JWT signature, expiry, and audience before invoking the interceptor, so the interceptor trusts the token and skips verification. A lightweight REQUEST interceptor Lambda extracts the `user_id` from the JWT claims and injects it into the tool arguments, so every downstream component knows who's calling without parsing tokens itself. The interceptor strips the inbound `Authorization` header so it doesn't override the Gateway's outbound SigV4 signature - this is critical for `GATEWAY_IAM_ROLE` to work correctly. + +> **Interceptor header stripping is critical.** The REQUEST interceptor Lambda strips the inbound `Authorization` header (Cognito JWT) before returning `transformedGatewayRequest.headers`. Per [AWS docs on interceptor header propagation](https://docs.aws.amazon.com/bedrock-agentcore/latest/devguide/gateway-headers.html#gateway-headers-interceptor-propagation), any headers returned by the interceptor are forwarded to the target. If the inbound Cognito JWT were forwarded, it would override the Gateway's outbound SigV4 `Authorization` header, causing a signature mismatch at the Runtime. The interceptor's `forwarded_headers = {k: v for k, v in headers.items() if k.lower() != "authorization"}` prevents this. + +### Cedar Policy Engine + +Before the request reaches the Runtime, the Gateway evaluates Cedar policies. These are declarative rules that control who can run which tools against which repos. A readonly role can call `get_task_status` and `list_tasks` but not `run_coding_task`. A global pattern can block all `*-production` repos for every role. The git provider enforces repo-level access separately via the user's OAuth token - Cedar handles the platform-level controls. + +### OpenCode Runtime Container (FastMCP Server, port 8000) + +The Gateway forwards the request to a single FastMCP server running inside a Firecracker microVM. Python was chosen because the entire stack - CDK, lambdas, tests - is Python. One language, one set of patterns, and compatibility with `agentcore deploy`. FastMCP provides Streamable HTTP transport, `ctx.elicit()` for interactive prompts, and `ctx.report_progress()` for streaming - all used by the sync and async paths. + +One process, one port, one codebase handles all 6 tools. The server exposes two coding execution modes plus four control tools: + +**Sync (`code` tool)** - stays connected, streams progress at each pipeline phase (clone 1/5, OpenCode running 2/5, credential scan 3/5, push 4/5, done 5/5), and returns the PR URL when finished. If git credentials are missing, `ctx.elicit()` presents the OAuth URL inline - the user authorizes in their browser and the pipeline resumes automatically. + +**Async (`run_coding_task` tool)** - writes a RUNNING record to DynamoDB, calls `app.add_async_task(job_id)` to register with AgentCore, and returns `{job_id, status: "RUNNING"}` immediately. The pipeline then runs as a background `asyncio.Task` inside the same microVM. No queue, no separate worker - the microVM isolation means each session is already sandboxed. The Runtime signals `HealthyBusy` while background tasks are active, so AgentCore won't route new sessions to an overloaded VM. Async tasks run fully autonomously - no mid-task clarification. OAuth must be resolved before submission (use `connect_git_host` first). + +The MCP server entry point is [`container/code_mcp_server.py`](../container/code_mcp_server.py). + +### The Pipeline (Shared Tool Implementations) + +Both sync and async paths execute the same five-step pipeline, implemented as composable tool functions under [`container/tools/`](../container/tools/): + +1. **[resolve_git_credential](../container/tools/resolve_git_credential.py)** - calls AgentCore Identity SDK to get the user's OAuth token for the git host. If the token doesn't exist yet, the sync path uses `ctx.elicit()` to prompt OAuth consent; the async path fails immediately with `git_host_not_connected`. +2. **[git_clone](../container/tools/git_clone.py)** - shallow clone (`--depth 1`) with optional sparse checkout. Uses the OAuth token for authentication. +3. **[run_opencode_acp](../container/tools/run_opencode_acp.py)** - spawns the OpenCode binary as a subprocess communicating via ACP protocol over stdin/stdout. Configurable timeout with SIGTERM -> SIGKILL escalation (5-second grace period). +4. **[scan_and_strip_credentials](../container/tools/scan_and_strip_credentials.py)** - regex scanner that checks modified files for AWS access keys, `sk-` API keys, PEM private keys, and high-entropy secret assignments. Replaces matches with `` before push. +5. **[git_push_and_create_pr](../container/tools/git_push_and_create_pr.py)** - commits, pushes with 3-retry rebase logic (fetch + rebase between retries to handle concurrent pushes), and creates a GitHub PR via the API. + +Failed tasks fail immediately - there are no task-level retries or dead-letter queues. The git push retries above are the only retry logic in the system, handling a specific recoverable failure (concurrent pushes to the same branch). + +### DynamoDB (Job History + Audit) + +DynamoDB stores lightweight audit records - not a state machine. Four states: RUNNING, COMPLETE, FAILED, CANCELLED. Records are partitioned by user (`PK = user#{user_id}`) so queries are naturally scoped. The `get_task_status` and `list_tasks` tools read from here; the pipeline writes on completion or failure. Each record includes the `runtime_session_id` for cross-session cancellation. See [`container/lib/dynamodb_helpers.py`](../container/lib/dynamodb_helpers.py). + +### Managed Session Storage + +AgentCore managed session storage provides filesystem persistence across microVM stop/resume. Git clones and partial work survive without custom S3 sync logic. The pipeline places work directories under the managed session path so if a microVM dies mid-task, a resumed session on a new VM picks up where it left off. + +### Cancellation + +Since all 6 tools run in the same process, `cancel_task` first attempts in-process cancellation: it checks the `_running_tasks` dict for the target `job_id`, sets the cancel flag, and calls `task.cancel()` on the asyncio task. If the job isn't running in-process (e.g., it's on a different session), `cancel_task` falls back to cross-session cancellation - it queries the job record from DynamoDB to get the `runtime_session_id`, then calls `StopRuntimeSession` to terminate the remote microVM. The DynamoDB record is updated to CANCELLED regardless of which cancellation path succeeds. + +### Observability + +OTEL metrics flow to the ADOT collector sidecar (managed by AgentCore) for CloudWatch GenAI observability dashboards. Every task is traceable per user - duration and files edited are recorded per job. Cost alarms and custom dashboards are not deployed by this stack; AgentCore's built-in GenAI observability provides token usage and cost visibility out of the box.

This is the standard AWS service-to-service auth pattern: simpler, no extra Cognito pool, no token management. + +**Critical dependency:** The REQUEST interceptor Lambda must strip the inbound `Authorization` header before returning `transformedGatewayRequest.headers`. Per [AWS docs on interceptor header propagation](https://docs.aws.amazon.com/bedrock-agentcore/latest/devguide/gateway-headers.html#gateway-headers-interceptor-propagation), headers returned by the interceptor are forwarded to the target. If the inbound Cognito JWT were forwarded, it would override the Gateway's outbound SigV4 `Authorization` header, causing a signature mismatch at the Runtime. + +### Dynamic Tool Discovery via Implicit Sync + +**Problem:** The Gateway needs to know which tools each Runtime exposes. + +**Solution:** Dynamic tool discovery via implicit sync during `CreateGatewayTarget`. When a target is created without `mcpToolSchema`, the Gateway calls `tools/list` on the Runtime automatically. Runtimes respond in ~1 second, well within the discovery timeout. Tool definitions stay in sync with the server code - no duplicated JSON to maintain. diff --git a/02-use-cases/opencode-on-agentcore/docs/HARDENING.md b/02-use-cases/opencode-on-agentcore/docs/HARDENING.md new file mode 100644 index 000000000..816078ea0 --- /dev/null +++ b/02-use-cases/opencode-on-agentcore/docs/HARDENING.md @@ -0,0 +1,142 @@ + + + +# Hardening + +This is the production-hardening guide for the sample. It covers Amazon Virtual Private Cloud (Amazon VPC), Amazon Bedrock, Amazon Bedrock AgentCore, and AWS Key Management Service (AWS KMS) configuration choices that differ between a demo deployment and a production one. The defaults in the CDK stacks optimize for cost and simplicity so you can stand up a dev or demo deployment quickly. The notes below describe how to take that deployment closer to production-ready: highly available NAT, enforced Cedar policies, budget alerts, and the known limitations you should design around. Controls are listed from highest to lowest operational impact. + +## NAT Gateway High Availability + +The default `nat_gateways=1` in [`../stacks/vpc_stack.py`](../stacks/vpc_stack.py) is a **cost optimization for dev and sample workloads**. It routes all outbound traffic from private subnets through a single NAT Gateway in one Availability Zone. + +For **production deployments**, set `nat_gateways` to match the number of AZs (default is 2, or the length of your `availability_zones` list). With a single NAT Gateway, an AZ failure takes out **all outbound connectivity** for the entire VPC, meaning the Runtime cannot reach Bedrock, GitHub, DynamoDB, or any other external service until the AZ recovers. + +To change this, update the `nat_gateways` value in [`../stacks/vpc_stack.py`](../stacks/vpc_stack.py): + +```python +# Production: one NAT Gateway per AZ for high availability +"nat_gateways": 2, # match your AZ count +``` + +The tradeoff is cost: each NAT Gateway adds ~$32/month plus data transfer charges. For dev/test environments where brief outages are acceptable, the single NAT Gateway default keeps costs down. + +## Cedar Policy Engine + +The `OpenCodePolicy` stack deploys a Cedar Policy Engine. Cedar policies are created post-deploy via [`../scripts/create-policies.py`](../scripts/create-policies.py) because the `CfnPolicy` CloudFormation resource handler has stabilization issues. The Gateway associates with the Policy Engine in **LOG_ONLY** mode by default, configured natively in CDK via `AWS::BedrockAgentCore::Gateway.PolicyEngineConfiguration`. In this mode, policy violations are logged but not blocked, so you can validate policy behavior before enforcing. + +**Switching from LOG_ONLY to ENFORCE mode:** + +Once you've reviewed the CloudWatch logs and confirmed the policies match your intent, update the `PolicyEngineConfiguration.Mode` property in [`../stacks/gateway_stack.py`](../stacks/gateway_stack.py) from `"LOG_ONLY"` to `"ENFORCE"` and redeploy with `cdk deploy`. + +**Adding custom policies (e.g., production repo deny):** + +Use [`../scripts/create-policies.py`](../scripts/create-policies.py) as a template. Action names follow the `{target}___{tool}` format (e.g., `opencode___run_coding_task`), and the resource must reference the specific gateway ARN. Use `validationMode="IGNORE_ALL_FINDINGS"` for policies referencing tools discovered dynamically. + +## Key Management Strategy + +The sample provisions a single customer-managed AWS KMS key (CMK) in [`../stacks/security_stack.py`](../stacks/security_stack.py) and threads it through every stack that needs encryption at rest. Summary: + +- **Key type:** Symmetric customer-managed CMK, one per deployment. +- **Rotation:** Automatic rotation is enabled (`enable_key_rotation=True`). AWS KMS rotates the key material annually; no action required on your part. +- **Key policy:** The default key policy permits the account root and grants use to the stack-created roles (Runtime execution role, Gateway role, Lambda roles). Review and tighten if you need to constrain which principals can use the key. +- **Alias:** `alias/opencode-cmk-{region}` for easy lookup. +- **Removal policy:** `RETAIN`, so `cdk destroy` does not delete the key. This prevents accidental loss of encrypted data in DynamoDB, CloudWatch Logs, Secrets Manager, or S3. Use [`../scripts/cleanup-retained-resources.sh`](../scripts/cleanup-retained-resources.sh) to remove the CMK alias and schedule key deletion when you're done with the sample. +- **Services using the CMK:** AWS Secrets Manager (OAuth app credentials), Amazon DynamoDB (job records), Amazon CloudWatch Logs (all log groups), Amazon S3 (CloudTrail bucket when enabled). Amazon Bedrock AgentCore managed resources (Gateway, Runtime, Policy Engine, Identity Vault) are encrypted with AWS-owned keys by default; these can be switched to customer-managed keys via the relevant service-level configuration if your threat model requires it. + +For a production deployment, consider: + +1. Splitting the CMK into per-data-type keys (one for secrets, one for logs, one for DynamoDB) if you need separate key policies or rotation schedules. +2. Adding explicit condition keys (`kms:ViaService`, `kms:CallerAccount`) to the key policy. +3. Enabling AWS CloudTrail data events on the CMK for full key-usage auditing. + +## AWS Budgets for Cost Control + +The `daily_cost_budget_usd` value in `cdk.json` (default: `50`) is a **reference value only**. It is not enforced by the stack -- there is no AWS Budget, alarm, or throttle created automatically. If Bedrock costs exceed this amount, no default alert fires unless you set up monitoring yourself. + +To catch runaway Bedrock costs, create an AWS Budget with daily notifications: + +1. Open the [AWS Budgets console](https://console.aws.amazon.com/billing/home#/budgets) or use the CLI +2. Create a **Cost budget** scoped to the `Amazon Bedrock` service +3. Set the budget amount to your `daily_cost_budget_usd` value and the period to **Daily** +4. Add two alert thresholds: + - **80% of budget** -- early warning that costs are trending high + - **100% of budget** -- immediate notification that the daily limit has been reached +5. Configure an SNS topic or email as the notification target + +Using the CLI: + +```bash +aws budgets create-budget \ + --account-id $CDK_DEFAULT_ACCOUNT \ + --budget '{ + "BudgetName": "opencode-daily-bedrock", + "BudgetLimit": {"Amount": "50", "Unit": "USD"}, + "TimeUnit": "DAILY", + "BudgetType": "COST", + "CostFilters": {"Service": ["Amazon Bedrock"]} + }' \ + --notifications-with-subscribers '[ + {"Notification": {"NotificationType": "ACTUAL", "ComparisonOperator": "GREATER_THAN", "Threshold": 80, "ThresholdType": "PERCENTAGE"}, "Subscribers": [{"SubscriptionType": "EMAIL", "Address": "your-email@example.com"}]}, + {"Notification": {"NotificationType": "ACTUAL", "ComparisonOperator": "GREATER_THAN", "Threshold": 100, "ThresholdType": "PERCENTAGE"}, "Subscribers": [{"SubscriptionType": "EMAIL", "Address": "your-email@example.com"}]} + ]' +``` + +For full setup options, see the [AWS Budgets documentation](https://docs.aws.amazon.com/cost-management/latest/userguide/budgets-managing-costs.html). + +## Known Limitations + +- **Outbound traffic from the microVM is not FQDN-restricted in v1.** The security group limits egress to port 443; AWS service traffic routes through VPC endpoints. Git clone and push traffic to any HTTPS host on the public internet is unfiltered via the NAT Gateway. +- **GSI1 hot-partition scaling cap.** The admin-monitoring GSI (`status#{status}`) has only 4 partition key values. At high volume this hits the ~3k RCU / 1k WCU per-partition limit. A sharding strategy is documented in [`../stacks/job_store_stack.py`](../stacks/job_store_stack.py) for when scale warrants it. +- **Amazon Cognito MFA is not enforced on the sample user pool.** The user pool is demo-scoped; you are responsible for enabling MFA ([Cognito MFA configuration](https://docs.aws.amazon.com/cognito/latest/developerguide/user-pool-settings-mfa.html)) and enforcing password policies suitable for your environment before routing real users through it. +- **No prompt-injection or output-content filter is applied to LLM I/O.** The pipeline relies on the upstream Amazon Bedrock model's built-in safety filters, a credential scanner ([`container/tools/scan_and_strip_credentials.py`](../container/tools/scan_and_strip_credentials.py)) that removes common credential patterns from pushed output, Cedar policies scoped to specific `opencode___{tool}` action ARNs, and microVM isolation per session. For stronger guarantees, layer on an [Amazon Bedrock Guardrail](https://docs.aws.amazon.com/bedrock/latest/userguide/guardrails.html) and extend the credential scanner's regex set. + +## Third-party dependencies and AI components + +This sample uses two third-party components at runtime, both referenced (not vendored) via standard package installers: + +- **[OpenCode](https://opencode.ai)** - MIT-licensed AI coding agent, installed at container build time from the upstream installer script ([`../container/Dockerfile`](../container/Dockerfile)). Upstream source: https://github.com/sst/opencode. Pin the version explicitly in the Dockerfile for reproducibility before promoting to production. +- **[FastMCP](https://gofastmcp.com)** - MIT-licensed MCP server framework, installed from PyPI via [`../container/requirements.txt`](../container/requirements.txt). + +The LLM itself is Amazon Bedrock-hosted Anthropic Claude, a pre-approved model available through the Amazon Bedrock marketplace. Bedrock enforces its own content filters and safety controls upstream of this sample; customer-side responsibility is limited to model access control via IAM (scoped to specific model ARNs in [`../stacks/agentcore_stack.py`](../stacks/agentcore_stack.py)) and application-level input/output sanitization. + +The sample processes user-supplied git repositories as transient input to the LLM. Repositories are cloned into the per-session Firecracker microVM, fed to OpenCode, and discarded when the session ends. They are not logged, persisted to customer-owned storage, or redistributed. The credential scanner runs between LLM output and the git push to reduce the risk of secrets leaking into the PR. + +## Deployment Notes + +### Tested regions + +This sample has been tested and deploys successfully in: + +- **us-east-1** (US East - N. Virginia) +- **eu-central-1** (Europe - Frankfurt) + +**us-west-2 may have deployment issues.** The `AWS::BedrockAgentCore::GatewayTarget.CredentialProvider` schema in us-west-2 was previously a version behind (missing the `IamCredentialProvider` sub-type). This may have been resolved since last tested. AgentCore Gateway is available in 14 commercial regions as of the latest documentation; check the [AgentCore supported regions page](https://docs.aws.amazon.com/bedrock-agentcore/latest/devguide/agentcore-regions.html) for the current list. Deploy to us-east-1 or eu-central-1 for confirmed compatibility. + +**Other regions - managed session storage.** `FilesystemConfigurations` on `AWS::BedrockAgentCore::Runtime` is documented in the CFN template reference but not yet accepted by the CFN schema validator in every region. [`../stacks/agentcore_stack.py`](../stacks/agentcore_stack.py) only emits the property in `us-east-1` (the only confirmed-deployable region where the Runtime schema also accepts it). In every other deployable region the managed session storage feature is disabled - work directories won't persist across microVM stop/resume, but everything else works. Override via CDK context `-c enable_filesystem_configurations=true` if your region's schema has since caught up. + +### Experimental CDK module + +[`../stacks/gateway_stack.py`](../stacks/gateway_stack.py) depends on `aws_cdk.aws_bedrock_agentcore_alpha`, an alpha/experimental CDK module. The module is used for: + +- `Gateway` - L2 construct for the AgentCore Gateway +- `CustomJwtAuthorizer` - Cognito JWT inbound authorization +- `GatewayExceptionLevel` - debug exception level +- `LambdaInterceptor` - REQUEST interceptor wiring +- `GatewayCredentialProvider.from_iam_role()` - GATEWAY_IAM_ROLE credential provider +- `Gateway.add_mcp_server_target()` - MCP target creation + +Alpha APIs may break across minor version bumps. `requirements.txt` pins `aws-cdk.aws-bedrock-agentcore-alpha` with a tight upper bound (currently `>=2.251.0a0,<2.252.0a0`) so minor version bumps of the alpha module require a deliberate synth-and-diff review. Upgrade by bumping both the lower bound and the upper bound together, then running `cdk synth --all` to confirm the template is unchanged. + +**Known alpha-module gap - `IamCredentialProvider` sub-object.** `GatewayCredentialProvider.from_iam_role()` emits only `{"CredentialProviderType": "GATEWAY_IAM_ROLE"}` in the synthesized template, omitting the sibling `CredentialProvider.IamCredentialProvider` sub-object that the CFN runtime handler requires. [`../stacks/gateway_stack.py`](../stacks/gateway_stack.py) works around this with an `add_property_override` escape hatch on the underlying `CfnGatewayTarget`. The override injects `{"IamCredentialProvider": {"Service": "bedrock-agentcore"}}` at the correct path. This works in regions whose CFN schema knows about `IamCredentialProvider` (currently us-east-1). us-west-2 is blocked by a separate regional schema lag - see the Tested regions section. + +**Known alpha-module gap - Gateway -> DefaultPolicy ordering.** The alpha `Gateway` L2 attaches IAM permissions (including `bedrock-agentcore:GetPolicyEngine`) via `add_to_principal_policy`, which CDK synthesizes into a `DefaultPolicy` resource that is a sibling of the Gateway in the template. When the Gateway resource carries a `PolicyEngineConfiguration` property, the CFN handler validates the policy-engine reference by calling `GetPolicyEngine` using the Gateway's role at creation time - which races the DefaultPolicy attachment and fails with `AccessDenied`. [`../stacks/gateway_stack.py`](../stacks/gateway_stack.py) adds an explicit `cfn_gateway.add_depends_on(cfn_default_policy)` to force the correct ordering. + +**Fallback path:** if the alpha L2 drifts, the L1 `aws_cdk.aws_bedrockagentcore.CfnGatewayTarget` with `McpTargetConfigurationProperty` is the documented alternative. The `PolicyEngineConfiguration` is already attached via an `add_property_override` escape hatch on the underlying `CfnGateway`, so it is unaffected by alpha-module drift. + +### Why `create-policies.py` is still a script + +`AWS::BedrockAgentCore::Policy` (the `CfnPolicy` resource) has a service-side stabilization issue: the CloudFormation resource handler reports `NotStabilized` / `Resource stabilization failed` even when policy creation succeeds, causing stack `CREATE_FAILED` and rollback. [`../scripts/create-policies.py`](../scripts/create-policies.py) bypasses CloudFormation entirely, polls `get_policy` for up to 60 seconds, and cleans up `FAILED` leftovers from previous attempts. + +**Unblock criterion:** this script can be migrated into CDK when AWS ships the service-side fix to `CfnPolicy` stabilization (tracked via the AWS "What's New" feed for AgentCore Policy). + +**Note:** `AWS::BedrockAgentCore::Gateway.PolicyEngineConfiguration` does **not** share this stabilization bug and is attached natively in CDK via an `add_property_override` escape hatch on the underlying `CfnGateway`. diff --git a/02-use-cases/opencode-on-agentcore/docs/MCP-CLIENTS.md b/02-use-cases/opencode-on-agentcore/docs/MCP-CLIENTS.md new file mode 100644 index 000000000..6a742bf6e --- /dev/null +++ b/02-use-cases/opencode-on-agentcore/docs/MCP-CLIENTS.md @@ -0,0 +1,148 @@ + + + +# MCP Clients + +This document is the client-configuration guide for connecting to the deployed AgentCore Gateway.

A compromised account operator can bypass every control the sample adds. +3. **The deployer reviews and approves the template before `cdk deploy`.** This is a sample repository, not a managed service. Customers read the code. +4. **Upstream package and binary integrity is out of scope.** Python packages from PyPI via `container/requirements.txt`, OpenCode from the upstream installer, and base container images from the public Docker registry are trusted to be what they claim. Production adopters are expected to pin exact versions (already called out in HARDENING.md) and layer on whatever supply-chain controls they need. +5. **Cognito users are provisioned by a trusted operator.** `self_sign_up_enabled=False` and the user pool is operator-managed. We do not model the case where a malicious user is admitted. +6. **The MCP client is trusted.** If the client is compromised, nothing about this sample's defences protects the user.

MCP Client → Gateway + +| ID | STRIDE | Threat | Control | +|----|--------|--------|---------| +| MC-S | Spoofing | Attacker presents a forged JWT | Gateway validates JWT signature/issuer/audience via `CustomJwtAuthorizer` bound to the Cognito user pool. Cognito uses RS256; forgery requires the private key held by AWS. | +| MC-T | Tampering | Attacker modifies MCP request in transit | TLS between client and Gateway. Gateway validates the full request before forwarding. | +| MC-R | Repudiation | User denies submitting a task | Every tool call is attributed to the JWT `sub` claim (`_user_id` injected by the interceptor) and recorded in DynamoDB with timestamps. Optional CloudTrail captures the API-level event. | +| MC-I | Information disclosure | JWT is exfiltrated from the client | JWT TTL is 24 h. Client-side storage is documented in MCP-CLIENTS.md; "Option A" (auto-refresh wrapper) avoids on-disk storage. **Residual risk**: if the client is compromised, the attacker can act as the user for 24 h. Mitigated operationally by rotating Cognito user credentials. | +| MC-D | Denial of service | Attacker floods the Gateway | AgentCore Gateway handles service-level rate limiting. **Customer responsibility**: add WAF rules if the Gateway is exposed to the public internet. | +| MC-E | Elevation of privilege | Low-privilege role invokes a high-privilege tool | Cedar policies bound to `opencode___{tool}` action ARNs; `readonly` role cannot invoke `run_coding_task` or `cancel_task`. **Residual risk**: Cedar engine runs in `LOG_ONLY` mode by default. **Customer responsibility**: flip to `ENFORCE` before production, per HARDENING.md. | + +### 2. Gateway REQUEST interceptor ([`lambda/interceptor/index.py`](../lambda/interceptor/index.py)) + +| ID | STRIDE | Threat | Control | +|----|--------|--------|---------| +| GI-S | Spoofing | Interceptor forwards a request with a fake `_user_id` | The interceptor only injects `_user_id` from a JWT the Gateway has already validated. If no valid JWT is present the tool call is not decorated with a user identifier. | +| GI-T | Tampering | Client smuggles a pre-set `_user_id` in tool arguments | The interceptor overwrites the `_user_id` in tool arguments with the JWT `sub`; any client-supplied value is clobbered. | +| GI-I | Information disclosure | JWT is logged to CloudWatch | The interceptor reads the JWT claims but does not log the raw token. Forwarded headers exclude `Authorization` (required for correctness anyway - see MC-S below). | +| GI-E | Elevation of privilege | Inbound JWT overrides outbound SigV4 signature | The interceptor strips the inbound `Authorization` header before returning `transformedGatewayRequest.headers`, so the Gateway's SigV4 signature reaches the Runtime unchallenged. This is critical for `GATEWAY_IAM_ROLE` correctness; see [docs/ARCHITECTURE.md#architectural-decisions](ARCHITECTURE.md#architectural-decisions). | + +### 3. Cedar Policy Engine ([`stacks/policy_stack.py`](../stacks/policy_stack.py)) + +| ID | STRIDE | Threat | Control | +|----|--------|--------|---------| +| CP-T | Tampering | Attacker edits Cedar policies | Policies are created post-deploy via [`scripts/create-policies.py`](../scripts/create-policies.py) using IAM-authenticated API calls. Only principals with `bedrock-agentcore:CreatePolicy/UpdatePolicy` can modify them. | +| CP-R | Repudiation | A denied call is not recorded | `LOG_ONLY` mode writes evaluation records to CloudWatch. `ENFORCE` mode adds a hard deny plus the same log entry. | +| CP-E | Elevation of privilege | A missing policy allows an unintended action | The default policy set is permissive by design (`readonly` denies + `*-production` deny). **Customer responsibility**: add organization-specific permits/forbids; verify coverage in `LOG_ONLY` before switching to `ENFORCE`. | + +### 4. Gateway → Runtime (SigV4) + +| ID | STRIDE | Threat | Control | +|----|--------|--------|---------| +| GR-S | Spoofing | Someone other than the Gateway signs a request to the Runtime | Runtime validates SigV4 against `GATEWAY_IAM_ROLE`. Forging requires the Gateway's role credentials. | +| GR-T | Tampering | Request body is modified in flight | SigV4 covers method, URL, headers, and body hash. Any tampering breaks the signature. | +| GR-I | Information disclosure | Runtime responses leak to a third party | Runtime → Gateway traffic is over TLS inside the AWS network. | + +### 5. Runtime microVM (FastMCP server, [`container/code_mcp_server.py`](../container/code_mcp_server.py)) + +| ID | STRIDE | Threat | Control | +|----|--------|--------|---------| +| RT-S | Spoofing | One session acts as another | Each session runs in its own Firecracker microVM with its own `session_id`. Tool calls carry `_user_id` from the interceptor. DynamoDB records are partitioned by `user#{user_id}`. | +| RT-T | Tampering | An attacker with in-process access modifies `_running_tasks` or `_cancel_flags` | In-process attack requires prior code execution inside the microVM - covered by OC-* and PL-* below. | +| RT-R | Repudiation | Runtime denies a job ever ran | DynamoDB RUNNING → terminal state transitions are idempotent and timestamped. AgentCore managed session storage retains work directories across microVM stop/resume in supported regions. | +| RT-I | Information disclosure | Logs or metrics leak sensitive data | CloudWatch log groups are encrypted with the customer-managed CMK. OTEL metrics do not include request bodies. **Residual risk**: task descriptions and repo URLs appear in error logs; document as "medium sensitivity". | +| RT-D | Denial of service | Async task never terminates | Each async task has a configurable per-call timeout (`timeout_minutes_default=10`, `timeout_minutes_max=30`). OpenCode subprocess terminates via SIGTERM → SIGKILL escalation with a 5-second grace period. | +| RT-E | Elevation of privilege | Tool call elevates beyond its declared action | Every tool signature validates inputs (`_validate_repo_url`, `_validate_git_ref` in [`container/pipeline.py`](../container/pipeline.py)). The execution role uses SigV4 scoped actions; see IR-* below. | + +### 6. OpenCode subprocess ([`container/tools/run_opencode_acp.py`](../container/tools/run_opencode_acp.py)) + +| ID | STRIDE | Threat | Control | +|----|--------|--------|---------| +| OC-T | Tampering | `OPENCODE_BINARY` env var points at an attacker binary | `_validate_opencode_binary` (called at FastMCP startup) requires an absolute path, a regular file, and executable bit.

The Runtime never sees it. +- **Risk:** None. The request fails cleanly at the edge. No background work is started. +- **Likely cause:** Lambda cold start issues or a bug in the interceptor code. Under normal operation this timeout is never hit. + +### Tool Times Out (10--30 min) + +- **What happens:** The container's Python code (`run_opencode_acp_impl`) catches `asyncio.TimeoutError` and calls `_terminate_process()`, which sends SIGTERM then SIGKILL after 5s if the process hasn't exited. +- **Effect:** The coding task is marked as `FAILED` with a timeout error. The job record in DynamoDB is updated. Any partial work (uncommitted file changes) remains in the session storage but is not pushed. +- **Risk:** Low. The process is forcefully terminated. No orphaned compute. +- **Likely cause:** Complex coding tasks, large repositories, or model latency. + +### Runtime Session Ends + +- **What happens:** The AgentCore service stops the microVM. +- **Effect:** Any in-flight tool execution is terminated. The MCP connection drops. The client receives a connection error or timeout. +- **Risk:** Medium. If a tool was mid-execution, the job status may not be updated to `FAILED`. The DynamoDB record could remain in `RUNNING` state (stale). +- **Mitigation:** Operators can query GSI1 for `status#RUNNING` jobs and reconcile stale records. + +### Gateway Idle Timeout + +- **What happens:** The Gateway closes the idle HTTP/SSE connection. +- **Effect:** The client loses its connection. However, for async tasks (`run_coding_task`), the background pipeline continues running in the Runtime because it is decoupled from the request lifecycle. +- **Risk:** High for sync tasks (`code` tool) -- the client loses the response. Low for async tasks -- the background pipeline completes independently and updates DynamoDB. +- **Mitigation:** Use `run_coding_task` (async) for long-running operations. Use `get_task_status` to poll for results. + +## Recommended Timeout Ordering + +Timeouts should be ordered so that inner layers time out before outer layers: + +``` +tool timeout < Runtime session < Gateway idle timeout +(10-30 min) (managed) (managed) +``` + +**Why this ordering matters:** + +1. **Tool < Runtime**: The tool should finish (or be killed) before the Runtime session ends. This ensures the job status is updated in DynamoDB and any cleanup (credential scanning, git push) can complete. If the Runtime dies first, the tool is killed without cleanup. + +2. **Runtime < Gateway**: The Runtime should remain alive for the duration of the Gateway connection. If the Gateway times out first on a synchronous call, the Runtime may continue processing a request whose response can never be delivered. For async tasks this is less critical since results are stored in DynamoDB. + +3. **Interceptor is independent**: The Interceptor timeout (5s) is a pre-processing step. It should always be much shorter than any other timeout since it only performs JWT extraction. + +### Current Configuration Assessment + +The current defaults follow the recommended ordering: + +| Layer | Timeout | Order | +|-------|---------|-------| +| Interceptor Lambda | 5 seconds | Shortest (pre-processing) | +| Tool (`timeout_minutes`) | 10--30 minutes | Inner | +| Runtime session | Managed by service | Middle | +| Gateway idle | Managed by service | Outer | + +The managed timeouts (Runtime session and Gateway idle) are controlled by the AgentCore service and are expected to exceed the tool-level timeout under normal operation.
