Reminders

macOS only — this server uses AppleScript to communicate with the macOS Reminders app.

A Model Context Protocol (MCP) server that lets Claude read and manage your macOS Reminders. Create, list, update, complete, and delete reminders directly from any MCP-compatible client such as Claude Desktop.

Requirements

• macOS
• Python 3.11+
• uv — install with curl -LsSf https://astral.sh/uv/install.sh | sh
• macOS Reminders app (you'll be prompted to grant Automation permission on first run)

Installation

git clone https://github.com/mhtb32/reminders-mcp.git
cd reminders-mcp
uv sync

Claude Desktop Setup

Add the following to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "🖊️ reminders": {
      "command": "/Users/YOUR_USERNAME/.local/bin/uv",
      "args": ["run", "--directory", "/path/to/reminders-mcp", "reminders-mcp"]
    }
  }
}

Replace YOUR_USERNAME and /path/to/reminders-mcp with your actual values, then restart Claude Desktop.
