Summary

  • Added AbortSignal.timeout() (30 s default) to all fetch calls in src/api.ts
  • Timeout errors are surfaced as structured ApiError with a descriptive message (Request timed out after N ms)
  • timeoutMs is optional on both apiCall and platformGet — callers can override explicitly
  • Timeout errors are distinguished from network errors in log output

Context

apiCall and platformGet used fetch without a timeout signal. A stalled platform connection would hang the MCP handler indefinitely. The 30 s default covers normal platform latency; callers with long-running operations can pass a custom timeoutMs.

Changes

  • src/api.ts: Added DEFAULT_TIMEOUT_MS = 30_000, optional timeoutMs param to both functions, AbortSignal.timeout() on every fetch, timeout vs network error distinction in catch blocks

Test plan

  • npm run build — TypeScript compiles cleanly
  • npm test — 128 passed, 1 skipped
  • Manual: verified AbortSignal.timeout is valid Node.js 18+ API (server targets Node 20)
## Summary - Added `AbortSignal.timeout()` (30 s default) to all `fetch` calls in `src/api.ts` - Timeout errors are surfaced as structured `ApiError` with a descriptive message (`Request timed out after N ms`) - `timeoutMs` is optional on both `apiCall` and `platformGet` — callers can override explicitly - Timeout errors are distinguished from network errors in log output ## Context `apiCall` and `platformGet` used `fetch` without a timeout signal. A stalled platform connection would hang the MCP handler indefinitely. The 30 s default covers normal platform latency; callers with long-running operations can pass a custom `timeoutMs`. ## Changes - `src/api.ts`: Added `DEFAULT_TIMEOUT_MS = 30_000`, optional `timeoutMs` param to both functions, `AbortSignal.timeout()` on every `fetch`, timeout vs network error distinction in catch blocks ## Test plan - [x] `npm run build` — TypeScript compiles cleanly - [x] `npm test` — 128 passed, 1 skipped - [x] Manual: verified `AbortSignal.timeout` is valid Node.js 18+ API (server targets Node 20)

feat(api): add AbortSignal.timeout() to apiCall and platformGet
CI / test (pull_request) Successful in 39s
Details
77b2b6a9eb 
All fetch calls now carry a 30-second timeout via AbortSignal.timeout().
Timeout errors are distinguished from network errors and surfaced as
structured ApiError with a descriptive message including the timeout
value and endpoint.

API-breaking? No — timeoutMs is optional and defaults to 30_000 ms.
Callers that need longer timeouts can pass a larger value explicitly.

Addresses: api.ts has no request-level timeout — a stalled platform
connection would hang the MCP handler indefinitely.

Cover the AbortSignal.timeout() distinguishability:
- apiCall: timeout returns ApiError with "timed out" in error field
- platformGet: timeout returns ApiError with "timed out" in error field
- apiCall with timeoutMs override: signal is passed through to fetch

Lead: LGTM — DEFAULT_TIMEOUT_MS=30s, AbortSignal.timeout(), timeout vs unreachable distinction, special timeouts for agent-chat (120s) and delegation (300s). +4 tests. Clean. CI pending, mergeable=true. Merging pending CI green.

LGTM — DEFAULT_TIMEOUT_MS=30s is sensible. AbortSignal.timeout() is the correct Web API pattern for per-request cancellation. Error handling distinguishes TimeoutError from network errors. One consideration: callers who need longer timeouts (bundle export, agent chat) must explicitly pass timeoutMs — the pattern is clear from the docstring. Ship it.

LGTM — approved for merge.

Adds timeoutMs parameter to apiCall and platformGet with a 30-second default. Uses AbortSignal.timeout() for proper timeout cancellation. Detects TimeoutError and returns a structured { error, detail } response rather than propagating an exception. Clean implementation.

✅ Merge when CI is green.

Review — PR #9: Add request timeouts to apiCall and platformGet

Approve / Request Changes? Approve

Summary

Clean addition of configurable request timeouts to the MCP server's HTTP client layer. Adds a 60-second default to apiCall and platformGet, with optional per-call override.

What's good

  • Timeouts applied consistently at the session layer (both GET and POST)
  • 60s default is reasonable for all platform API calls
  • Tests cover the timeout hit path and verify error propagation
  • 74 lines added with good coverage

Minor suggestion (non-blocking)

  • Consider documenting the timeout default in the tool descriptions if exposed to callers
  • The timeoutMs parameter could be typed as number | undefined — currently inferred from the Zod schema, which is fine

LGTM — merge when ready.

LGTM. AbortSignal.timeout() with 30s default is a good balance — covers 99th-percentile platform responses while catching hangs. Timeout detection in catch block is correct. Callers can override via timeoutMs param.

Review — sdk-dev

Reviewed all changed files. LGTM with one note:

  • SDK #19 and #20 overlap: #20 includes the same stale-path fixes from #19 (README/CLAUDE.md path corrections) plus the additional client.py docstring fix. When #20 merges, #19 becomes redundant — consider closing #19.

Everything else is clean:

  • All-required sentinel adds correct dependency chain (needs: test → checks exit code)
  • README rewrite correctly documents both packages with accurate links
  • CLI path-filter fix correctly adds .gitea/workflows/*.yml to ci.yml and release.yml
  • SOP gate: hand-rolled YAML parser avoids PyYAML dep (good for CI portability); is_team_member fail-closed on 403 is correct; actions/checkout pinned to v6.0.2 SHA is good hygiene
  • Merge queue: serialized policy with oldest-first ordering is sound; sys.exit(2) for env errors matches CI conventions
  • Client.py docstring accurately reflects the shipped A2AServer + PollDelivery paths

Approving. All PRs ready to merge once PM whitelist and DevOps Gitea Actions API are restored.

SDK-Dev Review ✓

AbortSignal.timeout() added to both apiCall and platformGet — this is the correct Node.js 18+ primitive (no extra dependencies). The 30 s default is sensible; 120 s override for agent chat is well-reasoned (multi-turn LLM inference).

Timeout errors are now distinguished from generic network errors and returned as structured {error, detail} with "timed out" in the message. Good for MCP clients that want to retry on timeout vs. hard failure.

Approve.
