Questions about Recurring Event Expander.

The practical details behind the request, access and result.

What is the Recurring Event Expander MCP?

It is a capability that takes complex recurrence rules (RRULEs) and turns them into a simple list of actual dates. This makes it much easier for your AI agent to understand and act on recurring schedules.

Can it handle complex rules like 'every 2nd Tuesday'?

Yes, it handles advanced logic including specific days of the week, month-day rules, and position sets like 'the second Tuesday'.

Does the Recurring Event Expander MCP support date exclusions?

Yes, it can handle exclusions (EXDATE) and additions (RDATE), ensuring your agent knows which specific dates to skip in a recurring series.

How do I use it for calendar automation?

You provide the recurrence string and a date range. The Connector returns a list of dates that your agent can then use to book meetings, check availability, or generate reports.

Can it tell me what a weird RRULE string actually means?

Yes, it can generate a human-readable summary of a technical recurrence string so you can verify what the rule actually does in plain English.

Is this for RFC 5545 standards?

Yes, it is specifically designed to parse and expand rules following the RFC 5545 standard, which is the standard for iCalendar files.

What is an RRULE?

An RRULE (Recurrence Rule) is a standard format defined in RFC 5545 used to describe recurring events, such as 'every Monday' or 'the last Friday of the month'.

How can I verify if my rule is valid?

You can use the validate_rrule capability to check your RRULE string for structural integrity and compliance with the iCalendar standard.

Can I exclude specific dates from the expansion?

Yes, when using expand_occurrences, you can provide a list of ISO 8601 timestamps in the exdates parameter to exclude them from the resulting list.
