What is Inbox Dog?
Gmail for Agents provides full Gmail API access—including read, write, search, draft creation, label management, and email sending—for AI agents. It supports multiple integration paths, a no‑code connection for non‑technical users, an MCP server that works with Claude, Cursor, Windsurf, and other MCP‑compatible agents, and a JavaScript SDK for custom code or backend applications.
The service uses pre‑verified OAuth credentials, eliminating the need for a Google CASA Tier 2 security audit and its associated cost and delay. Tokens are automatically refreshed, so agents maintain continuous access without manual intervention. The solution is open‑source under an MIT license, allowing inspection, self‑hosting, or use of the hosted service without a payment card requirement.
