## How to connect Excalidraw

Open Connections in your workspace and choose Connect next to Excalidraw. It needs no separate sign-in: choose Connect and it's ready. Name the account and choose Workspace under who can use it. That's the only time anyone signs in: your whole team, shared chats and Loops can use Excalidraw from then on. Or skip ahead and ask for the work: Maito sends you a link if Excalidraw isn't connected yet.

## Questions

### What is the Excalidraw MCP server URL?

Excalidraw publishes it at https://mcp.excalidraw.com/mcp, and it needs no sign-in.

### Can I use the Excalidraw MCP server from Slack?

Yes. Connect it to Maito once, then mention Maito in any Slack channel or send it a direct message. The same connection works by email and from Claude, ChatGPT, Cursor, Codex, Grok or Muse.

### Does everyone on my team have to connect Excalidraw?

No. One person connects it once and chooses Workspace. Then everyone in the workspace, shared chats and Loops can use Excalidraw, without signing in themselves. Choose Only me instead to keep it to your own chats.

### Do I have to connect Excalidraw before I ask?

No. If a request needs Excalidraw and it isn't connected yet, your agent sends you a link. Connect it, and the work picks up where it stopped.

### Can I limit what Maito does in Excalidraw?

Yes. After you connect, turn off any Excalidraw tools you don't want Maito to use, such as the ones that change data. Tools Excalidraw adds later stay off until you turn them on.
