Two ways to get GBrain into Cowork sessions:
For Team/Enterprise plans, an org Owner adds the connector:
- Go to Organization Settings > Connectors
- Add a new connector with the MCP server URL:
https://YOUR-DOMAIN.ngrok.app/mcp - Add Bearer token authentication in Advanced Settings
(create one with
gbrain auth create "cowork") - Save
Note: Cowork connects from Anthropic's cloud, not your device. Your server must be publicly reachable (ngrok, Tailscale Funnel, or cloud-hosted).
If you already have GBrain configured in Claude Desktop (via gbrain serve
stdio or a remote integration), Cowork gets access automatically. Claude
Desktop bridges local MCP servers into Cowork via its SDK layer.
This means: if gbrain serve is running and configured in Claude Desktop,
you don't need a separate server for Cowork.
- Remote server: works even when your laptop is closed, available to all org members
- Local Bridge: zero extra setup if Claude Desktop already has GBrain, but requires your machine to be running
