Codex

Connect Codex to your Whimsical workspace to visualize your codebase with clear diagrams. Ask it to map authentication flows, chart service dependencies, generate sequence diagrams from API logic, or create architecture diagrams from your code.

Codex can also create wireframes from code or prompts, and even turn those wireframes into working prototypes.

Get set up

  1. Install the Codex CLI and run:
codex mcp add whimsical --url https://mcp.whimsical.com/mcp

2. If you're using Codex desktop app, run the following prompt:

Add Whimsical MCP server as a streamable HTTP MCP server using name `whimsical-remote` and URL `https://mcp.whimsical.com/mcp`, then start OAuth login flow to authorize in browser.

Need access to local files? If you’d like Codex to work directly with files and code on your machine, you can use Desktop MCP instead. Desktop MCP runs through the Whimsical desktop app, which must remain open while you’re using it. Contact us to learn more.
