The Model Context Protocol (MCP) lets AI tools like Claude Desktop and Cursor connect to external services. AgentMailr ships an MCP server that gives your AI tool 30+ email tools without writing any code.

Claude Desktop Setup

Add this to your Claude Desktop config file (~/Library/Application Support/Claude/claude_desktop_config.json on Mac):

{
  "mcpServers": {
    "agentmailr": {
      "command": "npx",
      "args": ["-y", "@agentmailr/mcp-server"],
      "env": {
        "AGENTMAILR_API_KEY": "ak_your_key",
        "AGENTMAILR_API_URL": "https://api.agentmailr.com"
      }
    }
  }
}

Restart Claude Desktop. The email tools appear automatically.

Claude Code (CLI) Setup

Run this command to add the server globally:

claude mcp add agentmailr npx -y @agentmailr/mcp-server

Then set the environment variables in your shell profile.

Cursor Setup

In Cursor settings, go to MCP Servers and add:

{
  "agentmailr": {
    "command": "node",
    "args": ["/path/to/agentmailr-mcp/dist/index.js"],
    "env": {
      "AGENTMAILR_API_KEY": "ak_your_key"
    }
  }
}

Available Tools After Setup

Once connected, Claude or Cursor can use these tools:

  • create_inbox: Create a new inbox
  • get_otp: Wait for and return an OTP code
  • list_emails: Read emails in an inbox
  • read_email: Read a specific email
  • send_email: Send from an inbox
  • reply_to_email: Reply in a thread
  • wait_for_email: Block until an email arrives
  • And 20+ more tools

Hosted MCP Server

For remote access without running a local process, use the hosted MCP server:

{
  "url": "https://mcp.agentmailr.com/mcp",
  "type": "streamable-http",
  "auth": { "type": "bearer", "token": "ak_your_key" }
}
