Recurring Event Handling With Rrule Format Support

Create, search, and manage Google Calendar events via MCP.

Unique: Delegates recurrence logic entirely to Google Calendar's RRULE implementation rather than implementing custom scheduling logic, reducing maintenance burden and ensuring compatibility with Google Calendar's native recurrence features

vs others: More powerful than simple repeat-count scheduling because it supports RFC 5545 RRULE standard, enabling complex patterns like 'every 2 weeks on Monday and Friday' that would require custom logic in simpler systems

via “recurring event expansion with timezone-aware scheduling”

Calendar sync tool & universal calendar MCP server. Aggregate, sync and control calendars on Google, Outlook, Office 365, iCloud, CalDAV or ICS.

Unique: Implements RFC 5545 RRULE expansion with timezone-aware scheduling and DST handling, caching expanded instances to optimize repeated queries; includes EXDATE support for exception handling

vs others: Handles timezone-aware recurrence expansion natively, whereas many calendar libraries require manual DST adjustment or don't support complex RRULE patterns

via “recurrence rule parsing and expansion”

** - CalDAV Nectcloud calendar integration. Manage calendars, events, attendees, etc.

Unique: Implements full RFC 5545 RRULE parsing and expansion with support for complex patterns (BYMONTHDAY, BYDAY, BYWEEKNO, etc.) and exception handling, rather than supporting only simple daily/weekly/monthly patterns

vs others: Handles complex recurrence rules that simplified calendar APIs don't support, enabling accurate representation of real-world recurring events like 'last Friday of each month' or 'every 2 weeks on Monday and Wednesday'
