draw.io MCP (official)
draw.io's own server, which is a different proposition from the community one: it opens diagram content in the editor rather than pretending to draw it.
What it does
draw.io's own server, which is a different proposition from the community one: it opens diagram content in the editor rather than pretending to draw it. That makes it a handoff tool — the agent produces structure, a person adjusts layout. Honest about what generated diagrams still need.
Install
npx -y @drawio/mcpClient configuration
Paste this into your MCP client config (Claude Desktop, Cursor, or any client that reads mcpServers), then restart the client.

When to use it
Reach for this when the task needs diagrams inside the agent loop. Skip it if a plain shell command or a one-off script is enough — every server you add costs context and adds a failure mode.
Other TypeScript servers
- Filesystem — Gives an agent scoped read, write, and search access to directories you explicitly allow
- Memory — A persistent knowledge graph stored in a local JSON file, exposed through entities, relations, and observations
- Sequential Thinking — Gives the model a scratchpad for structured, revisable reasoning: numbered thoughts that can branch, revise, and conclude
