4. Click the Edit Config button to open claude_desktop_config.json

Option 2: Direct File Access

For macOS:

code ~/Library/Application\ Support/Claude/claude_desktop_config.json

For Windows:

code %APPDATA%\Claude\claude_desktop_config.json

2. Add Server Configuration

Add the following configuration to your claude_desktop_config.json:

{
  "mcpServers": {
    "apple-reminders": {
      "command": "mcp-server-apple-reminders",
      "args": []
    }
  }
}

3. Restart Claude Desktop

For the changes to take effect:

1. Completely quit Claude Desktop (not just close the window)
2. Start Claude Desktop again
3. Look for the tool icon to verify the Apple Reminders server is connected

Usage Examples

Once configured, you can ask Claude to interact with your Apple Reminders. Here are some example prompts:

Creating Reminders

Create a reminder to "Buy groceries" for tomorrow at 5 PM.
Add a reminder to "Call mom" with a note "Ask about weekend plans".
Create a reminder in my "Work" list to "Submit report" due next Friday.

Update Reminders

Update the reminder "Buy groceries" with a new title "Buy organic groceries".
Update "Call mom" reminder to be due today at 6 PM.
Update the reminder "Submit report" and mark it as completed.
Change the notes on "Buy groceries" to "Don't forget milk and eggs".

Managing Reminders

Show me all my reminders.
List all reminders in my "Shopping" list.

The server will:
