draw.io

MCP serverDev tools

This app lets your AI create draw.io diagrams for you right in chat. Diagrams come out as live, interactive draw.io files, and your AI can search a library of more than 10,000 shapes to build them. Once it is added, you can go from an idea or plan to a visual without leaving the conversation.

Install draw.io

The server’s own address, for the clients that take one directly. Or connect ahel once and every client you use reads it from one address, with the account kept on ahel rather than in each client’s config.

Claude Code
claude mcp add --transport http --scope user draw-io 'https://mcp.draw.io/mcp'
Run it once in your project, then open /mcp to approve any sign-in the server asks for.
Claude Desktop
https://mcp.draw.io/mcp
Add a custom connector in Settings, paste this address, and approve the sign-in.
Cursor
cursor://anysphere.cursor-deeplink/mcp/install?name=draw-io&config=eyJ1cmwiOiJodHRwczovL21jcC5kcmF3LmlvL21jcCJ9
Open the link and Cursor adds the server at that address.
ChatGPT
https://mcp.draw.io/mcp
In Settings, enable Developer mode, create an MCP app, and paste this address. Your plan and workspace must allow custom apps.
Codex
codex mcp add draw-io --url 'https://mcp.draw.io/mcp'
Run it once, then sign in with codex mcp login draw-io if the server asks for an account.

From the project's README

As published by jgraph/drawio-mcp in README.md. This repository publishes several servers, so only the opening is shown here.

The official draw.io MCP (Model Context Protocol) server that enables LLMs to create and open diagrams in the draw.io editor.

Four Ways to Create Diagrams

This repository offers four approaches for integrating draw.io with AI assistants. Pick the one that fits your setup:

	MCP App Server	MCP Tool Server	Assistant Plugins	Project Instructions
How it works	Renders diagrams inline in chat	Opens diagrams in your browser	Generates `.drawio` files, optional PNG/SVG/PDF export or browser URL	Claude generates draw.io URLs via Python
Diagram output	Interactive viewer embedded in conversation	draw.io editor in a new tab	`.drawio`, `.drawio.png` / `.svg` / `.pdf`, or browser URL	Clickable link to draw.io
Requires installation	No (hosted at `mcp.draw.io`)	Yes (npm package)	One-line plugin install (draw.io Desktop only for PNG/SVG/PDF export)	No — just paste instructions
Supports XML, CSV, Mermaid	XML only	✅ All three	XML only
