Give an AI agent its own inbox for replies, attachments, and automated follow-up. Connect through hosted MCP or use the API from your app.
AgentMail gives your AI agent a dedicated email address with an inbox it can access through an API or MCP. It makes sense when replies need to come back into the workflow, such as an intake agent that tracks attachments and follows up in the same thread.
Use the hosted MCP server and sign in to the intended AgentMail organization. This first check only lists inboxes.
Connect my AgentMail workspace to Claude Code. If it is not already configured, run:
claude mcp add --transport http agentmail https://mcp.agentmail.to/mcp
Ask me to complete AgentMail’s OAuth sign-in and choose the intended organization. Then call list_inboxes and report whether the connection works. Stop before creating an inbox, reading messages, or sending mail.
A list or an empty result means the account can answer the request. If it is the wrong organization, redo authorization before looking up messages. For Cursor or another API-key client, the MCP guide shows how to supply the key in an HTTP header. Keep the key in your local secret store.
The free tier lists three inboxes. The Developer plan is listed at $20 per month and includes custom domains. The vendor publishes separate daily and plan limits, so check its rate-limit documentation before designing a high-volume workflow. Resend Inbound is worth comparing when you mainly need received mail to trigger events in your existing application. Evidence: AgentTools checked the vendor’s MCP, authentication, and pricing documentation on November 9, 2026. The recipe was not run against a connected mailbox.
