Fixed with `workstream-mcp-server` console script and `python -m workstream_mcp`. +- Bearer token could appear in `RequestContext` repr and echoed gateway outputs. Fixed with `repr=False` and redaction on all tool/resource results. +- Runtime FastMCP registration was not tested against the closed catalogue. Fixed with runtime resource/tool/prompt and input-schema assertions. +- Scenario fixture used wall-clock time. Fixed with a stable scenario timestamp. +- `mcp_server/` was outside CI and review-gate scope.

Fixed by making the default HTTP gateway fail closed for unavailable backend APIs and requiring explicit scenario injection or `WORKSTREAM_MCP_GATEWAY_MODE=scenario`. -- Tool schemas were defined but not enforced. Fixed by validating each tool input through the Pydantic schemas and adding negative tests for invalid decisions, blank identifiers, non-dict submissions, and malformed findings. -- MCP server had no runnable entrypoint. Fixed with `workstream-mcp-server` console script and `python -m workstream_mcp`. -- Bearer token could appear in `RequestContext` repr and echoed gateway outputs. Fixed with `repr=False` and redaction on all tool/resource results. -- Runtime FastMCP registration was not tested against the closed catalogue. Fixed with runtime resource/tool/prompt and input-schema assertions. -- Scenario fixture used wall-clock time. Fixed with a stable scenario timestamp. -- `mcp_server/` was outside CI and review-gate scope. Fixed with an additive MCP CI job and internal review gate coverage. -- Merge intent referenced an undeclared successor chunk. Fixed by setting successor fields to `null`. +- The legacy task claim route leaves work in `claimed`, while MCP `claim_task` cannot expose a separate start transition. The production gateway now fails closed until Workstream provides an atomic contributor claim-to-work API. +- The legacy task release route releases a screened task and requires operator authority. It is no longer exposed through contributor `release_task`. +- Legacy submission creation does not supply durable request replay. The production gateway now fails closed for `submit_task` until that contract exists. +- Runtime scenario mode was removed. The temporary scenario gateway must be injected explicitly by tests and cannot be selected by environment configuration. +- Request IDs are UUIDs, matching current backend header validation. +- Streamable HTTP now uses FastMCP DNS-rebinding host/origin allowlists, allows only secure loopback defaults unless configured, and rejects unsupported SSE transport. +- Non-JSON upstream success bodies and unexpected handler failures now become safe MCP errors without stack traces or secret leakage. +- Tool input schemas are precise for submission packets, review findings, decisions, and UUID request IDs; `needs_revision` requires findings before the gateway call. +- The scenario fixture now implements replay-safe task/review lifecycle behavior solely for conformance tests. +- Secret-safe operation metadata is logged without bearer tokens or request bodies. ## Commands Run ```bash -(cd mcp_server && /opt/homebrew/Caskroom/miniforge/base/bin/python3.12 -m pytest -q) -(cd mcp_server && /opt/homebrew/Caskroom/miniforge/base/bin/python3.12 -m ruff check . --output-format concise) +(cd mcp_server && /tmp/workstream-mcp-venv/bin/python -m ruff check .) +(cd mcp_server && /tmp/workstream-mcp-venv/bin/python -m pytest -q) python3 scripts/check_stale_workstream_wording.py python3 scripts/check_markdown_links.py python3 scripts/check_stale_authorization_docs.py python3 scripts/check_stale_artifact_contracts.py python3 scripts/test_agent_gates.py -(cd backend && /tmp/workstream-backend-venv/bin/python -m ruff check app tests scripts --output-format concise) -(cd backend && /tmp/workstream-backend-venv/bin/python -m pytest -q tests/test_api_contract_e2e.py) git diff --check ``` ## Result Summary ```text -MCP tests: 18 passed. +MCP tests: 26 passed.
