Your AI assistant can draw here too
Claude, Cursor, GitHub Copilot, Windsurf — point any MCP client at your boards. It adds shapes, connections and comments in plain language, and everyone on the board watches it happen.
A board your assistant can reach
The Model Context Protocol is how AI clients talk to the tools you already use. Umlout runs an MCP server, so an assistant working in your editor can open one of your diagrams, add a class, wire it to another, and leave a comment explaining why — using your account, your permissions, and nothing else.
It is not a "generate a diagram" button. The board stays yours: the assistant is one more collaborator on it, and every change it makes syncs to whoever is watching, undoes like any other change, and shows up in the same history.
Connected in three steps
Generate a key
Profile → MCP API Keys → Generate New Key. Copy it now; for security it is never shown again. Five keys per account.
Paste config + key
Drop it into your client's config file and swap in the key. Takes about a minute.
Reload the client
Then tell it what to draw, and watch the board.
For any client that accepts a remote URL with custom headers.
{
"mcpServers": {
"umlout": {
"url": "https://www.umlout.com/mcp/sse",
"headers": {
"Authorization": "Bearer <YOUR_API_KEY>"
}
}
}
}Docs & troubleshooting: setup configs for every client, a reference for all 37 tools, auth and rate limits, and fixes for the usual connection problems live in the umlout-mcp docs on GitHub (opens in a new tab).
