Livediagram MCP Server

A collaborative diagram editor that works without signing in. Open a link, draw, share. Real-time presence, cursors, comments, per-tab activity log with surgical revert. The canvas never sits behind an auth wall, so the friction to start is "open the link, start drawing.". It is available as a remote MCP endpoint.

Teams that work with collaborate and diagram and want a hosted endpoint instead of running a local process. The project is written in TypeScript.
