      What this check looks for
    Description, as the server wrote it
    Use this when the user wants a calendar invite, an .ics file, or an add-to-calendar link (Google Calendar, Outlook, Office 365, Yahoo) for one event or one repeating event: a webinar, class, meeting, party, deadline, or launch. Takes the title, local start/end and the event's time zone (city or IANA zone), or dates only for all-day events, plus optional location, description, link, organizer name, reminders, and a repeat rule (daily, weekly on chosen weekdays, monthly by date, nth weekday such as the last Friday, or the first/last weekday of the month, yearly; with count, until date, and skipped dates). Returns a downloadable RFC 5545 .ics file with time zone data, four add-to-calendar links, and the first 5 dates in the event's zone and optional attendee zones, with daylight saving changes flagged. Does not send invitations, read or change anyone's calendar, or track RSVPs. Do not use for a list of different sessions (use generate_event_series) or for finding a meeting time across zones.

      What this check looks for
    Description, as the server wrote it
    Use this when the user wants one calendar file (.ics) that adds several different events at once: a course or class schedule, a training program, a conference agenda, match fixtures, or a list of webinars on irregular dates. Takes 1-40 sessions (each with its own start, end or duration, optional title, location and note) plus a shared time zone, location, details, link, organizer name and reminders. Returns one .ics file with one event per session and a dated list of the sessions. Does not make add-to-calendar web links per session, send invitations, or change anyone's calendar. Do not use for an event that repeats on a regular pattern (use generate_calendar_event with recurrence).

    Annotations the server declares

    • title: Generate calendar file for a schedule
    • readOnlyHint: true
    • destructiveHint: false
    • openWorldHint: false
    • idempotentHint: true

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
