check_availabilityread-only

Return the open meeting slots a Lucie Sync host offers, plus their booking rules (durations offered, minimum notice, how far ahead you can book, buffer between meetings). Returns only bookable slots and policy — never the host's raw calendar. Use this to find a time before proposing one to the user. Slots are absolute instants (ISO-8601 UTC). Pass the booker's viewerTimeZone so times display in

book_meeting

Book a confirmed meeting on a Lucie Sync host's calendar at a specific start time. This is a real write: it creates a calendar event and emails both the host and the booker. Always call check_availability first and use one of the open slots it returns. Before calling, (1) show the booker the specific date/time you're about to book — in their own time zone — and get their explicit confirmation,

find_group_timesread-only

Given several Lucie hosts (by @handle), return the meeting times when ALL of them are free — the intersection of their availability — for a meeting of the given length.

Times are absolute instants; pass viewerTimeZone so they show in the organizer's local zone.

create_group_event

Create a Lucie group event (a poll) for several participants, pre-filled with candidate times when everyone is free (the intersection of their availability). Returns a vote link to share: participants pick which proposed times work, and people WITHOUT a Lucie handle can vote manually too. This is a write (creates a poll) but sends no emails and touches no calendars. Confirm the title, participants

book_group_meeting

Confirm a group meeting at a specific time across several Lucie hosts (by @handle), creating ONE shared Google Calendar event with everyone invited. YOU (the connector's owner) are the organizer and host the event on your calendar — no organizer handle needed. This is a real write: it re-verifies every participant (you included) is free at that instant and refuses if anyone isn't — so it never
