Implementation Reference
- apple_notes.py:301-347 (handler)The @mcp.tool() decorator registers and defines the handler for the 'update_note' tool. It escapes the note name and content, constructs an AppleScript to find and update the note's body (searching all accounts if no account specified), executes it via subprocess, and returns success/error messages.
