With Codex connected to your Whimsical workspace it can help you visualize your codebase with clear visual diagrams. Ask it to map authentication flows, chart service dependencies, or generate a sequence diagram from your API logic.

It can also make wireframes based on your code, or direct prompts - and even turn those wireframes into working prototypes.

Now, start a new Codex session and ask it to visualize your code

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