From c43f52a21c0e329eb090f897da047fbd1c56beb9 Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 7 Sep 2026 18:12:26 +0530 Subject: [PATCH] feat(mcp): stdio MCP server that starts with nothing MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit An agent should be able to discover what a server can do before it authenticates. Today it cannot: the only MCP endpoint is streamable-HTTP behind OAuth 2.1, so `tools/list` is a 401, and a directory crawler in a bare container sees a server that refuses to introduce itself. The Fastify API cannot serve that discovery, because importing apps/api/src/mcp/server.ts reaches, before any transport exists: mcp/server.ts -> mcp/auth.ts -> config/env.ts process.exit(1) on the first missing variable mcp/server.ts -> mcp/tools/index.ts -> mcp/tools/record-decision.ts -> lib/decisions.ts -> queue/embeddings.ts ioredis dials on import mcp/server.ts -> mcp/tools/dev/index.ts -> db/index.ts postgres.js pool (Three eager ioredis clients in total: queue/embeddings.ts, queue/pdf-generation.ts, mcp/tools/query-embedding.ts. Observed as three TCP connects 1.3s into a bare import, followed by an unhandled ioredis error event.) So packages/mcp-stdio imports none of it: initialize / tools/list answered offline from tools.generated.json, captured at build time from the real createMcpServer() over an in-memory transport tools/call forwarded over HTTPS to a workspace Everything needing a service is on the CALL path, established on first use. A missing dependency fails one call with a stated cause and a reason code on stderr (stdio.not_configured, stdio.upstream_unreachable, stdio.upstream_http_error, stdio.upstream_bad_payload, stdio.tool_error) — never a boot failure, never a silent catch. A build-time capture is a second copy of the truth, and second copies rot, so mcp-stdio-manifest.test.ts regenerates and diffs it. __ui_probe is excluded from the manifest: it is a development probe registered unconditionally in mcp/server.ts and live in the hosted tools/list, and it should not appear in a public directory listing. Left registered upstream — removing it is a separate decision. Dockerfile at the repo root builds only this package (its one dependency is the MCP SDK, not the ~90 production deps of apps/api), installs with a frozen lockfile and --ignore-scripts so nothing reaches the network mid-install, and runs as an unprivileged user with no port and no healthcheck — a probe writing to stdout would corrupt the JSON-RPC stream. node:22-slim rather than node:20-slim: package.json declares engines.node >= 22. Also fills in root package.json description/keywords/repository/license/homepage, which were absent. Verified with no environment at all (env -i, PATH only): initialize -> serverInfo {"name":"mnema","title":"Mnema","version":"1.0.0"} tools/list -> 45 tools exit code 0 Re-run from a tree mirroring the image layout (source removed, pnpm symlinks preserved) with the same result. `docker build` itself is NOT yet run — no container runtime on the authoring machine.
