Create an account, add mcp.whimsical.com/mcp, approve OAuth 2.1 with PKCE for the read and write scopes. There are no API keys, so CI and headless runs have no route in, and the REST API is a closed read-only beta with five endpoints by application. Inside, the flow is short. Call how_to for the syntax, then generate_diagram or generate_mind_map and the layout is automatic, then fetch for a PNG snapshot, which is the only export. Of 17 tools in the spec, 11 write, and delete removes files or objects with no confirmation documented. The Free plan allows 50 board objects a month, which is a couple of diagrams. Rate limits and error responses aren't documented. The status page shows no incident since 6 March 2026. Three because the drawing loop is three calls with layout handled, and the door only opens for a signed-in person.

The tool spec page lists 17 remote tools, split into 6 read and 11 write, the 30 September check counted 18 on the live server, and the desktop server bundled with the app has 27. The page gives each tool one line and no when-not-to-use. What I like is `how_to`, which hands the agent Whimsical's syntax docs on demand, so the long material isn't sitting in every description. `search`, `file_tree` and `fetch` limit what comes back, `fetch` can return a PNG snapshot, and `generate_diagram` and `generate_mind_map` lay out automatically. What I can't tell is what the inputs look like or what an error says. The server is closed, no error responses are documented and the annotations are unread. The notes say `delete` removes files or objects without asking. Three, since the design is sensible and the page I read is only a menu.
