fix(mcp): detect orphaned stdio host and self-terminate - #297
fix(mcp): detect orphaned stdio host and self-terminate#297geunwoobaek wants to merge 10 commits into
Conversation
StdioServerTransport only listens for stdin data/error events, so a stdio-mode server never notices when its host (Claude Code) dies without sending SIGTERM/SIGINT first. The child is left running as an orphan (ppid 1) with nothing to talk to, observed spinning at sustained high CPU indefinitely until manually killed. Detect this two ways - stdin closing and a periodic ppid check - and run the existing shutdownFn immediately once either fires.

Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to This PR includes a fork-publishing workflow that can delete the remote branch, publish unrelated or sensitive local files, or push to the wrong destination under common repository states, and its cleanup logic can stall after a non-settling session close. These are concrete integrity, security, and availability risks, so the PR is not merge-ready until the publishing safeguards and cleanup behavior are addressed or explicitly accepted by an owner.

The orphan watcher treated `process.ppid === 1` as proof the host was gone, but plenty of healthy launches have ppid 1 from birth — mcp/Dockerfile runs `tini` as PID 1, and `MCP_TRANSPORT=stdio` is a documented override, so a containerized stdio server self-terminated 5s after every start with a live client on the other end. The same test also misses real orphans on Linux, where a `systemd --user` session or another subreaper adopts them instead of PID 1. Compare the current parent pid against the one captured at startup instead: re-parenting is the actual signal, and it catches both cases. Extract the whole watcher into `core/orphan-watch.ts` so the predicate is unit-testable (`main()` runs at import time and cannot be exercised directly), which also resolves the TDZ-by-luck capture of `orphanCheckInterval` before its `const` initializer. Add a 2s hard exit deadline around teardown. Shutdown only exited via `.finally()`, so a transport close that never settles — the exact failure mode behind these high-CPU orphans — left the process alive anyway. Have the signal handlers skip teardown once orphan shutdown owns it, rather than racing a second `shutdownFn()`. Verified live against the built server: real orphan (re-parented, stdin still open) exits in ~5s with `reason: reparented`; ppid-1-from-birth with stdin open stays up; stdin EOF exits immediately; a healthy parent is untouched. - npm run mcp:typecheck, npm run mcp:build - cd mcp && npm test (161/161, 12 new) - npm run test:server (947 passing, 1 skipped) - npm run test:client (330/330) - bash .claude/skills/file-headers/scripts/check-headers.sh Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
`transport.sessionId` is assigned by the SDK *while* it handles the initialize request, so reading it right after `new StreamableHTTPServerTransport(...)` always yielded undefined and the `?? randomUUID()` fallback filed the session under an id no client was ever given. Every follow-up request then missed the `transports` lookup and fell through to `Bad Request: No valid session or initialization` — the official SDK client could not finish a handshake, and each attempt leaked an McpServer that nothing could reach or close. Register from the SDK's `onsessioninitialized` callback instead, which fires with the same id that goes out in the `mcp-session-id` response header, and close the transport/server pair when a handshake never produces one. Legacy SSE was unaffected — `SSEServerTransport` assigns its session id in the constructor — and is covered here to keep it that way. Verified end-to-end against a running server: initialize -> 202 on notifications/initialized -> tools/list (97) -> tools/call; the real SDK client completes a session, `activeSessions` goes up by exactly one and returns on DELETE; an unknown session id still 400s. The new tests fail against the previous code (2/4) and pass after the fix. - npm run mcp:typecheck, npm run mcp:build - cd mcp && npm test (165/165, 4 new) - mcp stdio smoke: tools=97 auth=ok Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…rvers Terminating a session is optional in the MCP protocol — the SDK client's `close()` does not send `DELETE /mcp` (only `terminateSession()` does) — so a client that crashes, is killed, or simply walks away left its session, and the `McpServer` behind it, tracked for the life of the process. On a long-running HTTP server that grows without bound. Track `lastActivityMs` per session, refreshed by any request that routes to it, and sweep sessions idle past `MCP_HTTP_SESSION_TIMEOUT_MS` (default 30 minutes; floor of 60s so a typo cannot reap live sessions; `0` opts out). The sweep interval is derived from the timeout and capped at 60s, and the timer is unref'd so it never holds the process open. `startHttpServer` also returns `reapIdleSessions(now?)` so the sweep can be forced deterministically from tests and by operators. Verified against a live server with a 60s timeout: an abandoned session was closed by the sweep at 86s idle and `activeSessions` returned to 0, while a client making a call every 20s stayed connected across 120s — well past the timeout — and released cleanly on terminateSession(). Broader functional sweep on this build (95 checks, stdio + Streamable HTTP): 97-tool catalog with parity between transports, 20 read-only tools returning real results on each, mutation guards denying with the documented message, wrong-typed arguments and unknown tools rejected without wedging the server, and legacy SSE completing a full session and releasing it on disconnect. - npm run mcp:typecheck, npm run mcp:build - cd mcp && npm test (170/170, 5 new) - mcp stdio smoke: tools=97 auth=ok Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Follows the update-project-docs mapping for the stdio orphan shutdown, the Streamable HTTP session fix, and the new MCP_HTTP_SESSION_TIMEOUT_MS knob. The env var now reaches the same surfaces as its neighbours MCP_HTTP_PORT and MCP_TRANSPORT, and the lifecycle behaviour is documented where an operator would look for it. - SETUP.md, mcp/.env.example: the new env var alongside the other MCP_HTTP_* settings. - ARCHITECTURE.md: two bullets under MCP "Safety and transport" covering stdio self-termination and HTTP session reclamation. - DEPLOYMENT.md + docs/DEPLOYMENT.md: session accounting for the long-running HTTP service, and activeSessions as the signal for clients dropping without terminating. - wiki/index.html: env-table row plus a transport-lifecycle paragraph, with zh/vi/ko/es translations in wiki/i18n-content.js per .claude/rules/wiki-i18n.md (inline <code> tags preserved), and the cache busted — sw.js CACHE_NAME wiki-v98 -> wiki-v99 and i18n-content.js?v=79 -> 80 in both index.html and the sw precache list. - .claude/skills/mcp-operations/references/runbook.md: a lifecycle section so an orphan-shutdown log line reads as expected behaviour, not a fault. docs/MCP.md and mcp/README.md already carried this from the code commits. Intentionally skipped: README.md and its translations plus the root .env.example, which carry only MCP_HTTP_AUTH_TOKEN — MCP_HTTP_PORT and MCP_TRANSPORT are absent there too, so adding a transport tuning knob would break that convention. - doc-coverage.sh MCP_HTTP_SESSION_TIMEOUT_MS: hits every doc its neighbours hit - client wiki-i18n suite 4/4 (prose coverage, metadata, asset-version sync) - prettier clean on every touched file Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

…surfaces `origin` in this repo is the upstream, so a plain `git push origin <branch>` on a fork-based PR updates the wrong branch and leaves the PR untouched — the failure this skill exists to prevent. It covers reading the PR's head metadata, confirming push rights (fork owner, or upstream maintainer with maintainerCanModify), the descendant check that stops an accidental force-push over a contributor's work, author-identity verification, the repo's verification suite, the push refspec, and post-push confirmation that the PR head actually moved. Mirrored to all three surfaces the repo maintains, with openai.yaml metadata for the Codex/skills.sh ones, and added to NATIVE_SHARED_SKILLS in scripts/validate-agent-extensions.js so parity is enforced rather than assumed. CLAUDE.md and AGENTS.md each gain a pointer beside the existing skill rules. The step-5 verification block is this repo's actual commands rather than the generic example, and the Co-Authored-By guidance now says to copy the trailer from the live harness instructions so the model name cannot go stale in a checked-in file. Adding a skill moves the discoverable repository total from 75 to 76, which plugins-marketplace.test.js pins against the source tree. Updated everywhere it is documented: README plus the CN/ES/KO/VN mirrors, docs/PLUGINS.md, .codex/README.md, ARCHITECTURE.md, index.html, and wiki/index.html with the matching zh/vi/ko/es keys in wiki/i18n-content.js.

Thanks for your contribution! I need to bundle in some fixes in this PR as well, and I can take of this PR from now on and will merge soon. You don't have to worry about it and the stuff I'm adding |
All four findings verified against the code before fixing; all four hold.
- orphan-watch: `shutdown` is injectable, so an implementation that throws
synchronously bypassed the `.catch()` and escaped into the process-level
exception path. Start the chain from a resolved promise. The new test fails
against the previous code with an uncaught `closed synchronously`.
- index.ts: `onSignal` only guarded against orphan shutdown, so SIGINT
followed by SIGTERM while the first `shutdownFn` was still awaiting ran
teardown twice and raced `stdioTransport.close()` with `server.close()`.
Pre-existing on master, but this PR touches that function. Verified live:
three signals in a row now produce exactly one "shutting down" line.
- http-server: the `lastActivityMs` doc pointed at `{@link touch}`, a helper
that does not exist — the timestamp is refreshed inline in the `/mcp` and
`/messages` handlers. My error when I inlined it.
- SETUP.md: the session-timeout row omitted the `[60000, 86400000]` clamp and
the invalid-value fallback that docs/MCP.md and mcp/README.md both state,
so `1000` looked like it would be honoured.
- cd mcp && npm test (171/171, 1 new)
- npm run mcp:typecheck, npm run mcp:build
- npm run test:server (947 passing, 1 skipped), npm run test:client (330/330)
- live: SIGTERM still exits cleanly; SIGINT+SIGTERM+SIGINT shuts down once

quoted shell variable for the PR number before invoking gh pr view, replacing
the angle-bracket placeholder. Apply this change at
.agents/skills/push-to-forked-pr/SKILL.md lines 23-24,
.claude/skills/push-to-forked-pr/SKILL.md lines 23-24, and
.codex/skills/push-to-forked-pr/SKILL.md lines 23-24, preserving the existing
requested JSON fields and workflow.
- Around line 120-125: Prevent detached HEAD from producing a destructive
empty-source refspec in the push flow: update the command block using FORK_REPO,
HEAD_BRANCH, and LOCAL_BRANCH in .agents/skills/push-to-forked-pr/SKILL.md lines
120-125, .claude/skills/push-to-forked-pr/SKILL.md lines 120-125, and
.codex/skills/push-to-forked-pr/SKILL.md lines 120-125 to push
HEAD:${HEAD_BRANCH} or explicitly abort when LOCAL_BRANCH is empty; keep all
three copies consistent.
- Around line 29-36: Update the internal-PR path in all three
copies—.agents/skills/push-to-forked-pr/SKILL.md lines 29-36,
.claude/skills/push-to-forked-pr/SKILL.md lines 29-36, and
.codex/skills/push-to-forked-pr/SKILL.md lines 29-36—to capture HEAD_BRANCH from
headRefName, perform the explicit headRefOid ancestry validation before pushing,
and push with git push origin "HEAD:${HEAD_BRANCH}" instead of an unspecified
local branch.
- Around line 40-43: Update the origin verification in the three skill files:
.agents/skills/push-to-forked-pr/SKILL.md lines 40-43,
.claude/skills/push-to-forked-pr/SKILL.md lines 40-43, and
.codex/skills/push-to-forked-pr/SKILL.md lines 40-43. Replace the fetch-URL
check with validation of git remote get-url --push origin against the expected
upstream before internal-PR pushes, while retaining the authentication check.
In `@README-CN.md`:
- Line 1785: Update the remaining skills.sh CLI repository-skill count in the
README installation block from 75 to 76, matching the counts already shown in
the surrounding section.
In `@wiki/i18n-content.js`:
- Around line 118-120: Update the localized marketplace counts from 75 to 76 in
wiki/i18n-content.js lines 118-120 (Chinese translation) and 3090-3093 (Korean
translation), keeping the surrounding translations unchanged.
- Around line 118-120: Update the stale localized skill counts in the Chinese
and Korean translations within the i18n content mappings, changing each
occurrence of 75 repository skills to 76 while leaving the surrounding
translated text and formatting unchanged.

Nitpick comments:
In `@index.html`:
- Line 2808: Update COUNTED_DOCS in the marketplace test to include index.html,
ensuring the existing skill-count consistency check validates the landing page
alongside the other counted documents.

Timestamp: 2026-08-19T04:02:11.170Z
Learning: Apply the `push-to-forked-pr` skill whenever updating a PR whose head branch lives on a fork — `origin` here is the upstream, so a plain `git push origin` updates the wrong branch and leaves the PR untouched.

Timestamp: 2026-08-19T04:02:11.170Z
Learning: Apply the `version-release` skill for every release bump: patch for backward-compatible fixes/small improvements, minor for larger backward-compatible capabilities, and major for breaking/fundamental changes; synchronize root, desktop, OpenAPI, snapshots, and generated plugin metadata, create or reuse the matching `v<version>` GitHub milestone, and assign the release PR plus linked closing issues to it.

Timestamp: 2026-08-18T17:17:30.266Z
Learning: When implementing bounded SQLite query execution in Claude-Code-Agent-Monitor, preserve support for both database backends across the worker-thread boundary. Review the change as a cross-cutting server-side architectural change and update or validate all affected routes, rather than treating it as isolated to server/routes/query.js.

Findings addressed in 2cab010; remaining scope is intentional and requested by the maintainer.
Three 75s survived the 75 -> 76 update because my verification grep reused the same patterns as the replacement, so it could only confirm what it had already changed — a self-fulfilling check. - README-CN.md: "发现仓库中的 75 个技能" and the install-block comment - README-KO.md: "75개 저장소 스킬" - wiki/i18n-content.js: the zh and ko marketplace translations, which said 75 while their English keys said 76 Swept with a pattern-independent regex (any 75 within 12 characters of skill/技能/스킬/habilidad/repository) plus a key-vs-translation comparison that flags any entry whose English says 76 and translation says 75. Both clean. Found by CodeRabbit. - node --test server/__tests__/plugins-marketplace.test.js (131/131) - client wiki-i18n suite 4/4 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…kill counts Prevent the push-to-forked-pr skill's example commands from deleting the remote branch on a detached HEAD, gate origin pushes on the actual push URL, make the internal-PR fast path do an explicit ancestry check, replace `git add -A` guidance with explicit staging, keep all three skill copies (.agents/.claude/.codex) in sync, add the missing invocation-safety gate to both openai.yaml manifests, and fix the remaining stale 75->76 skill counts in README-CN.md and the wiki i18n content (with a cache-bust version bump).

`.superpowers/` has been in .gitignore since line 55, but four files were committed before that entry existed and gitignore does not apply to already- tracked paths, so they kept shipping in the repo: a README, a 69 KB brainstorm wireframe, and two stale server state files (a PID and a server-stopped marker). `git rm -r --cached` untracks them and leaves the working copies on disk, so local agent workspaces are unaffected. The existing .gitignore rule takes over from here — verified with `git check-ignore`. This only removes them going forward. The blobs remain in history; purging those needs a filter-repo rewrite and a force-push of master, which is not something to bundle into a feature PR. - npm run test:server (947 passing, 1 skipped) - node scripts/validate-agent-extensions.js - bash .claude/skills/file-headers/scripts/check-headers.sh Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Summary
StdioServerTransportonly listens for stdindata/errorevents, so a stdio-mode MCP server never notices when its host process (e.g. Claude Code) dies without sendingSIGTERM/SIGINTfirst — stdin just closes silently.ppid1) with nothing left to talk to. Observed several such orphans on a dev machine spinning at sustained 60-90% CPU for many hours until manuallykill -9'd, sinceSIGTERMnever reached a running handler while the process was stuck.mcp/src/index.tsnow detects this two independent ways in stdio mode — the stdinend/closeevents, and a periodic (5s) check ofprocess.ppid === 1— and runs the existingshutdownFnimmediately once either fires, then exits.Test plan
