[
  {
    "domain": "@gmail.com",
    "server": "smtp.gmail.com", 
    "port": 587
  },
  {
    "domain": "@outlook.com",

  }
]

Start the MCP Email Server with:

python -m mcp_email_server (--dir /path/to/attachment/directory)

Add to your Claude settings:

{
  "mcpServers": {
    "email": {
      "command": "D:\\conda\\envs\\mcp\\python.exe",
      "args": [
        "C:\\Users\\YourUserName\\Desktop\\servers\\src\\email\\src\\mcp_server_email",
        "--dir",
        "C:\\Users\\YourUserName\\Desktop"
      ],
      "env": {
        "SENDER": "2593666979q@gmail.com",
        "PASSWORD": "tuogk......."
      }
    }
  }
}

{
  "mcpServers": {
    "email": {
      "command": "uv",
      "args": [
        "~\\servers\\src\\email\\src\\mcp_server_email",
        "--dir",
        "C:\\Users\\YourUserName\\Desktop"
      ],
      "env": {
        "SENDER": "2593666979q@gmail.com",
        "PASSWORD": "tuogk......."
      }
    }
  }
}

The server supports the following attachment file types:

• Documents: doc, docx, xls, xlsx, ppt, pptx, pdf
• Archives: zip, rar, 7z, tar, gz
