Whimsical MCP Server

The Whimsical MCP server gives your AI coding agent a Whimsical workspace to work in. Ask it to create flowcharts, mind maps, wireframes, sequence diagrams, or sticky notes from your conversation. Iterate with follow-up prompts, open a board in Whimsical to edit and share it, or search your workspace for boards to reference. It is available as a remote MCP endpoint.

Teams that want a hosted documentation endpoint instead of running a local process.
