iCloud CalDAV โ€” Direct Calendar Access

Manage iCloud Calendar directly via CalDAV protocol. No third-party services, no data leaves your machine except to Apple's servers.

When to Use

Activate when the user wants to: Check their calendar or upcoming events Create new calendar events Delete existing events List available calendars Do NOT use for: Reminders (use apple-reminders skill if available) Contacts (CalDAV is calendar-only) Non-iCloud calendars (Google, Outlook, etc.)

Prerequisites

Required credentials: APPLE_ID โ€” Your Apple ID email address APPLE_APP_PASSWORD โ€” An app-specific password (NOT your regular Apple ID password) To generate app-specific password: Go to appleid.apple.com Sign in โ†’ Sign-In and Security โ†’ App-Specific Passwords Generate a new password Use this password (not your regular one)

Quick Start

# Set credentials export APPLE_ID="your.email@icloud.com" export APPLE_APP_PASSWORD="xxxx-xxxx-xxxx-xxxx" # List calendars ./scripts/caldav.py list-calendars # List events for next 7 days ./scripts/caldav.py list-events --days 7 # Create an event ./scripts/caldav.py create-event \ --title "Team Meeting" \ --start "2025-07-23T14:00:00" \ --duration 60 \ --calendar "Work"

Available Operations

OperationCommandDescriptionList calendarslist-calendarsShow all iCloud calendarsList eventslist-eventsEvents in a date rangeCreate eventcreate-eventAdd new calendar eventDelete eventdelete-eventRemove event by filename or UID

Creating Events

# Basic event ./scripts/caldav.py create-event \ --title "Dentist Appointment" \ --start "2025-07-25T09:30:00" \ --duration 30 # With location and description ./scripts/caldav.py create-event \ --title "Project Review" \ --start "2025-07-26T14:00:00" \ --duration 60 \ --location "Conference Room B" \ --description "Q3 planning review" \ --calendar "Work" # All-day event ./scripts/caldav.py create-event \ --title "Vacation" \ --start "2025-08-01" \ --all-day

Batch Operations

Note: CalDAV does not support native batch operations. To create multiple events, run the script multiple times: # Create multiple events by running the command multiple times ./scripts/caldav.py create-event --title "Meeting 1" --start "2025-07-26T10:00:00" --duration 60 ./scripts/caldav.py create-event --title "Meeting 2" --start "2025-07-26T14:00:00" --duration 60 ./scripts/caldav.py create-event --title "Meeting 3" --start "2025-07-27T09:00:00" --duration 60 iCloud handles rapid sequential requests well, but there is no single API call for creating multiple events.

Deleting Events

# Delete by filename ./scripts/caldav.py delete-event \ --file "event-name.ics" \ --calendar "Calendar" # Delete by UID (searches calendar for matching event) ./scripts/caldav.py delete-event \ --uid "openclaw-xxx@openclaw.local" \ --calendar "Calendar" Warning: Deletions are permanent. iCloud may have its own backup, but standard CalDAV DELETE immediately removes the event.

Date/Time Formats

ISO 8601: 2025-07-23T14:00:00 (assumes local timezone if none specified) With timezone: 2025-07-23T14:00:00+08:00 All-day: 2025-07-23 (date only)

Security Notes

Credentials are read from environment variables only No credentials are logged or stored All communication is HTTPS to caldav.icloud.com App-specific passwords can be revoked anytime at appleid.apple.com
