From 5485c85e4087c6f83deeb354ba61c9fe61c4f771 Mon Sep 17 00:00:00 2001 From: Oto Macenauer Date: Wed, 21 Oct 2026 15:02:35 +0200 Subject: [PATCH] feat(mcp): add the MCP server on the official TypeScript SDK protocol/ registers search_documents, list_documents, read_document and the kb:// resources on the SDK v2 McpServer with zod 4 schemas. transport/ is a stateless Streamable HTTP handler (Origin check, 64 KiB body cap, per-client and global rate limits, in-flight cap, timeout) with /healthz and designed browser error pages; config.ts is the only reader of argv and KB_MCP_*. Build step 3b also bundles the server into one minified dist/_mcp/server.mjs (~410 KB; English-only zod locales, the SDK's Workers validator instead of Ajv) and writes dist/_error/not-found.html. The fragment server serves the endpoint through the same handler. Golden byte-exact protocol tests (UPDATE_GOLDEN=1), bundle-vs-source equivalence and a size budget pin the behaviour. A Makefile fronts the npm scripts; CI lints with make lint.
