MCP server for creating Whimsical diagrams

What you get

A third-party Model Context Protocol (MCP) server that enables the creation of Whimsical diagrams agentically. This server integrates with Whimsical's API to generate diagrams from Mermaid markup.

Create Whimsical diagrams using Mermaid markup generated by the MCP Client (Claude, Windsurf, etc.)
Returns both the Whimsical diagram URL and a base64 encoded image to allow the Client to iterate on it's original markup
