Whimsical MCP server

The Whimsical MCP server connects your Whimsical workspace to any AI tool that supports the Model Context Protocol. It gives the tool secure, OAuth-protected access to read and write in your workspace, so you can create flowcharts, sequence diagrams, mind maps, wireframes and docs from a prompt, and search the files you already have.

What you can do

Turn a description or image into a diagram:

Create a flowchart of a typical OAuth flow

Create a sequence diagram of how Slack decides to send a notification

Search your workspace

Find the system architecture diagram I made last month

Summarize the user flow we mapped out

Plan visually

Create a mind map of the key features for this project

Make a wireframe outline for a new settings page
