Connect an AI tool (MCP)

livediagram has an MCP server, so you can connect it to an AI tool you already use, like Claude, and then find, view, create, and edit your diagrams from inside that tool. Point the AI at a codebase and ask for a control-flow diagram, or ask it to tweak an existing one, and the result is saved to your account.

You need an account

Connecting an AI tool is a signed-in-only feature, the same as API tokens and teams. The canvas, sharing, and real-time collaboration stay account-free for guests, but driving your diagrams programmatically is an advanced, opt-in capability that needs an account. On a self-hosted instance that hasn't enabled accounts, the feature isn't available.

Connecting

In your AI tool, add a connector / MCP server pointing at https://mcp.livediagram.app/mcp. The first time, your tool opens a livediagram page asking you to approve the connection (you'll sign in if you aren't already). Approving creates an API token behind the scenes and hands it to your tool. From then on the connection just works.

The token it creates is an ordinary API token: it appears in the Explorer's API tokens page and you can revoke it there any time to disconnect the tool. Like all tokens, it lasts six months.

What the AI can do

The connection exposes four tools:

• Find diagrams — search your diagrams by name.
• Read a diagram — get a tab's contents and an inline picture of it.
• Create a diagram — turn a request into a new diagram; the server lays it out cleanly.
• Update a diagram — rework a whole tab or make a small adjustment.

The AI does the thinking; livediagram validates, lays out, saves, and renders what it produces. A token has full read and write access to your diagrams, so only connect tools you trust, and revoke the token if you stop using one.
