Add the Terminal49 MCP server as a custom app in Gemini so it can answer questions with live container and shipment tracking data, at gemini.google.com and in the Gemini mobile app.
Personal Google accounts only. Google currently supports custom apps only for personal Google accounts, for users 18 or older in the US, in English. They aren’t available with work or school (Google Workspace) accounts. On a work account, use Antigravity instead.
No API key required. The Terminal49 MCP server supports OAuth 2.1 with Dynamic Client Registration, so Gemini registers itself and you sign in with your Terminal49 credentials in the browser.

​
Prerequisites

  • A personal Google account that meets Google’s requirements above, with Keep Activity turned on. Custom apps are unavailable when it’s off.
