Add G2X to Claude on the web as a custom connector and sign in with your G2X account.
https://mcp.g2x.com/mcp as the server URL, then choose Continue until Claude shows its sign-in settings.On the Free plan you can add one custom connector. On a Team or Enterprise plan, an owner adds G2X once in Organization settings → Connectors (Add → Custom → Web), with the same name, address and sign-in settings. Everyone else then opens Customize → Connectors, finds G2X and chooses Connect.
Connectors belong to your Claude account, so G2X works in the Claude desktop app too.
