mcp-eventkit

MCP server for Apple Reminders using the native EventKit framework via PyObjC. No tokens, no sync services — reads and writes directly to the Reminders database on macOS.

Requirements

  • macOS (Apple Silicon or Intel)

  • Python 3.13+

  • uv

  • Reminders access granted in System Settings → Privacy & Security → Reminders


Related MCP server: Apple Reminders MCP Server

Running

uv run --with mcp --with pyobjc-framework-EventKit python server.py

On first run, macOS will prompt for Reminders access. If denied, grant it in System Settings → Privacy & Security → Reminders, then restart.

Claude Desktop / Claude Code Config

Add to your MCP server config:

{
  "mcpServers": {
    "reminders": {
      "command": "/opt/homebrew/bin/uv",
      "args": [
        "run",
        "--with", "mcp",
        "--with", "pyobjc-framework-EventKit",
        "python",
        "/path/to/server.py"
      ]
    }
  }
}

Replace /path/to/server.py with the absolute path to this file.


Known Limitations

  • No support for subtasks, tags, location reminders, or recurring reminders

  • Due dates are stored as NSDateComponents — timezone behavior depends on the system calendar

  • macOS only (EventKit is not available on Linux/Windows)
