inbox.dog provides Gmail OAuth and API access so AI agents can read, write, search, and send email with full scopes without passing Google's CASA Tier 2 audit themselves.
Developers building Claude, Cursor, or custom agents that need production Gmail write access without running their own security audit.
Self-hosted deployments require your own Google OAuth credentials and CASA audit for production Gmail write access.
inbox.dog lets agents connect to Gmail with write-capable OAuth, offering hosted keys, MCP tooling, and an open-source path for teams that prefer to self-host.
