Troubleshooting

  • OAuth window doesn't open. Check your default browser is set and pop-ups aren't blocked. On macOS you may need to grant Claude.ai (web) accessibility permissions.
  • Tools don't appear after install. Restart the host completely. Some hosts cache the tool list at startup.
  • 403 on calls. Re-approve OAuth — the cached token may have expired or had scopes revoked.
  • Still stuck? Drop a note on GitHub Issues with the host name and the error message.
