Troubleshooting

A few things to check:
  • You must be a workspace admin in Claude to add a Custom Connector.
  • The Client ID must be exactly b82803e6-31d4-47e0-9d7e-db9826ee451b with no extra spaces.
  • The account you’re signing in with on the Allo consent screen must have an active Allo account.
Reload the Claude conversation. Open the connector status panel in Claude and confirm Allo is listed as connected. If it isn’t, remove the connector and add it again following the steps above.
This is a standard MCP guard rail that Claude shows for any third-party connector — it’s not specific to Allo. It’s safe to proceed and authorize Allo.
