Feature Request: Add events_update and events_delete tools

[IGI2]

First of all, thank you for creating iMCP, great app!

I've been using iMCP with Claude and noticed that the Calendar service currently supports:

• calendars_list – list available calendars
• events_fetch – get events with filtering
• events_create – create new events

However, I'm missing two essential tools for complete calendar management:

• events_update – update an existing event
• events_delete – delete an event by ID

Use case

When Claude creates an event with incorrect dates (e.g., a two-day event instead of a single day), there's no way to fix it programmatically – I have to manually delete and ask Claude to recreate it.

Reference implementation

The icloud-calendar-mcp project implements these tools via CalDAV. Their API looks like this:

update_event:
  - event_id: string (required)
  - title: string (optional)
  - start_time: string (optional)
  - end_time: string (optional)
  - description: string (optional)
  - location: string (optional)

delete_event:
  - event_id: string (required)

Since iMCP uses Apple's native EventKit framework, the implementation should be straightforward using:

• EKEventStore.remove(_:span:commit:) for deletion
• Direct property modification + EKEventStore.save(_:span:commit:) for updates

Would you consider adding these tools?
