Bug: Unable to Configure Figma MCP Server – OAuth Error OAuth app with client id command-code doesn't exist

Summary

Unable to configure the Figma MCP server because the OAuth flow fails with the error OAuth app with client id command-code doesn't exist after signing in to Figma using Google.

Expected Behavior

The browser should open, authentication with Figma should complete successfully, and the Figma MCP server should be added to the MCP configuration.

Actual Behavior

The browser opens as expected, and I sign in to Figma using Sign in with Google. After authentication, an error page is displayed with the message:

OAuth app with client id command-code doesn't exist

Steps to reproduce the issue

1. Run either of the following commands:

   cmd mcp add figma https://mcp.figma.com/mcp
   

   or

   cmd mcp add --transport http figma https://mcp.figma.com/mcp
   

2. A browser window opens for Figma authentication.

3. Sign in to Figma using Sign in with Google.

4. Observe that the authentication fails and displays the error:

   OAuth app with client id command-code doesn't exist

Additional context

No response

Beginne damit, das Figma-MCP-Setup unter Linux mit cmd mcp add figma https://mcp.figma.com/mcp zu reproduzieren, und verfolge dann den OAuth-Flow, der den Client-ID-Fehler command-code erzeugt. Als erledigt gilt die Aufgabe, wenn die Figma-Authentifizierung abgeschlossen ist und der MCP-Server zur MCP-Konfiguration hinzugefügt wurde.
