TOOLS_EXTERNAL_SERVICE_UNAVAILABLE
Issue
The app that the tool calls didn't respond in time or returned a server error. The problem is on the app's side, not in your connection or your request. While you connect a tool, this error means the app's sign-in service returned server_error or temporarily_unavailable.
Resolution
- Wait a few minutes and try again. If you were connecting a tool or setting up a connector, click Connect again.
- Check the app's status page for an outage.
- If the error continues, ask your admin to check the app's status and any usage limits on the account that Glean uses. For a custom MCP server, the server's owner can check its logs.
