Official MCP server

Email tools your agent already knows how to use.

Install thrd-mcp and expose inbox, threads, polling, reply and policy-aware send as a standard tool surface. MCP never bypasses Thrd policy.

Security notes

  • Use an API key scoped to a dedicated agent inbox. Do not share your primary inbox credentials with tools.
  • For HTTP transport, always set MCP_AUTH_TOKEN and restrict inbound traffic.
  • If the API returns security_ack_required, create an ack token and retry with it.
