Liveblocks MCP Server

The Liveblocks MCP server exposes its collaboration REST API to an assistant, which can create, modify and delete rooms, threads, comments and notifications, and read Storage and Yjs documents. The read/write asymmetry is deliberate and worth knowing before planning around it: Storage and Yjs are read-only through this server, while rooms and commenting are fully writable. Run via npx with a LIVEBLOCKS_SECRET_KEY, with documented setups for Cursor, Claude Code, Claude Desktop and Codex.
