Notes and caveats
- Implementation lives in app/api/mcp/route.ts of the langfuse-docs repo.
- VS Code setup is documented as a one-click install link and Command Palette steps rather than a config snippet.
- For clients without streamable HTTP (for example Windsurf) the docs use npx mcp-remote as a local proxy.
- The docs search is also available as a REST endpoint at https://langfuse.com/api/search-docs.
- No stage label in the docs.
