About draw.io MCP Server

The official draw.io repository offers four ways for AI assistants to create diagrams: a hosted MCP App server that renders interactive diagrams inside the conversation, a local MCP tool server that opens diagrams in the draw.io editor, assistant plugins that write .drawio files with optional PNG, SVG or PDF export, and plain project instructions. The README documents what data leaves your machine for each option.

draw.io MCP Server is an open-source project written primarily in JavaScript, with 5.5k stars on GitHub. It was last updated in September 2026.
