Three steps

  1. Create a free 0n3 account and connect WhatsApp Business. Paste a key or sign in; it lands in your vault, encrypted.
  2. Install 0n3 into Gemini CLI. Google's terminal agent. One command at user scope.
  3. Ask Gemini CLI: whoami. Then: "Send a text message in WhatsApp Business".
Install (user scope)
gemini mcp add --scope user --transport http 0n3 https://0n3.app/mcp -H "Authorization: Bearer <your 0n token>"

The line above carries a placeholder; 0n3.app/install mints a real key named for Gemini CLI and fills it in.
