AgenticEmail MCP Server

Hosted email for AI agents over the Model Context Protocol

---

AgenticEmail ships a hosted MCP server so any MCP-compatible agent (Claude, Cursor, Codex, custom agents) can create inboxes and send, receive, and reply to real email as native tool calls - no custom glue code.

The server is remote (streamable HTTP). There is nothing to install or run locally.

Connect

{
  "mcpServers": {
    "agenticemail": {
      "url": "https://api.agenticemail.dev/mcp",
      "headers": {
        "Authorization": "Bearer ${AGENTICEMAIL_API_KEY}"
      }
    }
  }
}

Get an API key at agenticemail.dev - free while you build. Scoped keys work here too, so an agent only sees the inboxes you grant it.

Tools

Tool	Description
create_inbox	Provision a new addressable inbox
list_inboxes	List inboxes the key can access
list_threads / get_thread	Browse conversations and load full thread history
list_messages / get_message	Read parsed inbound and outbound messages
send_message	Send a message from an inbox
reply_to_message	Reply within an existing thread

Example

Create an inbox for the onboarding flow, send a welcome email to new@example.com, then watch for their reply.

The agent calls create_inbox, then send_message, and reacts to the reply through your webhook or WebSocket stream.

Beyond MCP

The same platform is available as a REST API, with webhooks, real-time events, custom domains, SMTP compatibility, and official TypeScript and Python SDKs.
