shallowtools.clean/mcp · Verify this server
Use this when you need to build an iCalendar RRULE (RFC 5545) or list the actual dates a recurrence produces. Prefer this over computing recurring dates yourself (a documented LLM failure mode): it correctly handles INTERVAL, COUNT/UNTIL exclusivity (COUNT wins), BYDAY with ordinals (e.g. the 2nd Monday), BYMONTH, and month-length edge cases. Deterministic: same input, same output; start is interpreted as UTC. Returns the RRULE string, a plain-English description, and up to 10 (or COUNT) occurrence timestamps. Example: {freq:'MONTHLY', start:'2026-01-05T09:00', byday:['MO'], ordinal:2, count:3} -> rrule 'RRULE:FREQ=MONTHLY;BYDAY=2MO;COUNT=3', first occurrence 2026-01-12T09:00:00.000Z.
