claude-code - 💡(How to fix) Fix MCP Gmail auth hangs indefinitely after browser authentication [1 comments, 2 participants]

TL;DR

The issue can be resolved by investigating the authentication callback handling in the CLI, potentially related to the auth callback URL.

Guidance

• Verify that the auth callback URL https://claude.ai/api/organizations/.../mcp/start-auth/... is correctly configured and accessible.
• Check for any errors or warnings in the output or logs after pressing Enter, which might indicate the cause of the hang.
• Inspect the /mcp command implementation to ensure it properly handles the authentication callback and completes the MCP connection.
• Consider adding logging or debugging statements to the authentication flow to identify where the process hangs.

Notes

The exact cause of the issue is unclear, and further investigation is needed to determine the root cause. The provided information suggests a potential issue with the authentication callback handling.

Recommendation

Apply workaround: Modify the authentication flow to include additional logging or debugging to identify the cause of the hang, as the root cause is currently unknown.
