You can connect Whimsical and Claude in two ways ✌️

• Use Whimsical's desktop MCP server with Claude Code
• Add the Whimsical remote MCP to Claude desktop, or Claude in your browser

Claude Code

Give Claude Code a direct line to your Whimsical workspace so it can turn your codebase into clear visual diagrams. Ask it to map authentication flows, chart service dependencies, or generate a sequence diagram from your API logic, and see the results live in Whimsical.

Get set up

With the Whimsical desktop app installed and open, run this command in your terminal:

Then start a new Claude Code session and ask it to visualize your code.

Note: The Whimsical desktop app must be open for the MCP server to run.

Claude desktop or Claude.ai (web)

Connect Whimsical to Claude and turn your conversations into real, editable diagrams. Describe a user journey, a decision tree, or a product flow in plain language, and Claude will create it directly in the chat. From there, you can open it in Whimsical to refine it, or share it with your team.

2. Find Whimsical in the MCP list, or add it manually with the URL https://mcp.whimsical.com/mcp
