Connect the Whimsical MCP server to Maito with one sign-in, and your whole team can use it from Slack or email: “Make a mind map of everything customers asked for this quarter.”

Whimsical makes flowcharts, mind maps, wireframes and diagrams. Connect the Whimsical MCP server to Maito once, and everyone on your team can use Whimsical from Slack, by email, or from Claude, ChatGPT, Cursor, Codex, Grok or Muse. Nobody else has to sign in.

## How to connect Whimsical

Open Connections in your workspace and choose Connect next to Whimsical. You sign in to Whimsical in a new tab, and that's the whole setup. 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 Whimsical from then on. Or skip ahead and ask for the work: Maito sends you a link if Whimsical isn't connected yet.

## Questions

### What is the Whimsical MCP server URL?

Whimsical publishes it at https://mcp.whimsical.com/mcp, and it signs in with OAuth, so there's no key to copy.

### Can I use the Whimsical 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 Whimsical?

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

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

No. If a request needs Whimsical 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 Whimsical?

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