Whimsical MCP Server
A Model Context Protocol (MCP) server that enables the creation of Whimsical diagrams programmatically. This server integrates with Whimsical's API to generate diagrams from Mermaid markup.
Demo
Here's an example of a complex system architecture diagram created using this MCP server and Claude - it shows the Model Context Protocol (MCP) architecture itself:
Features
- 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
Installation
Installing via Smithery
To install Whimsical MCP Server for Claude Desktop automatically via Smithery:
npx -y @smithery/cli install BrockReece/whimsical-mcp-server --client claude
Manual Installation

yarn install
# Build the project
yarn build
Integration with MCP Client
Update the MCP Client's config to point to this repository's dist folder eg:
{
"mcpServers": {
"whimsical": {
"command": "node",
"args": [
"/path/to/this/repo/whimsical-mcp-server/dist/index.js"
]
}
