Agentmail Mcp

AgentMail MCP hooks your AI assistant directly into email. You get 17 tools for creating inboxes, sending messages, managing threads, and handling drafts. Three setup paths: a hosted OAuth server at mcp.agentmail.to (zero install), npx for Node, or pip for Python. The Node version is the full toolkit, the Python package ships with fewer tools and lags behind. Works across Claude Desktop, Cursor, VS Code, Windsurf, and anything else that speaks MCP. Grab an API key from console.agentmail.to and drop the config into your MCP settings. The OAuth route is cleanest if your client supports it, otherwise pass keys through env or CLI flags.

AgentMail MCP

Prefer the hosted Streamable HTTP server:

https://mcp.agentmail.to/mcp

It avoids a local Node.js process and the slower release cadence of the published local MCP package.

Claude Code, Codex, and Cursor

Use OAuth. Do not put an empty API key in the configuration.

{
  "mcpServers": {
    "agentmail": {
      "type": "http",
      "url": "https://mcp.agentmail.to/mcp"
    }
  }
}

Claude Code can also install it directly:

claude mcp add --transport http agentmail https://mcp.agentmail.to/mcp

Complete the browser sign-in on first connection. Multi-organization OAuth sessions can use the server's organization-selection tools.

Claude.ai, Claude Desktop, and ChatGPT connectors

These apps add the server as a connector and complete OAuth in the browser. No API key is needed.
