Integration details

Description

Caly is a scheduling tool: people book meetings with you on your event types, inside the working hours you set. The Caly plugin lets ChatGPT and Codex work with your own Caly calendar. What it can do: - Read your event types (the kinds of meeting people can book, with their length and booking link) and your working-hours schedules. - Find free start times for an event type over a date range, in the time zone you choose. - List your upcoming, past, cancelled or unconfirmed bookings, filtered by attendee, event type or time window, and open one booking's details. - Book a meeting for an attendee on one of your event types. Caly sends its usual confirmation email and calendar invite. - Move a booking to a new free time. Caly notifies the attendees. - Cancel a booking in two steps: the first request only returns a confirmation token, and the booking is cancelled only after you confirm which meeting it is. Caly notifies the attendees. Tools: seven read-only tools (whoami, list_event_types, get_event_type, list_schedules, find_available_slots, list_bookings, get_booking) and three that change bookings (create_booking, reschedule_booking, cancel_booking). Who it is for: anyone with a Caly account who wants to check their availability and manage their meetings from a conversation. How it connects: you sign in to Caly with OAuth and approve the connection on Caly's consent screen. The plugin acts only on your own event types, bookings and schedules, with your normal Caly permissions. Limitations: one approval covers every operation, with no per-operation permissions. The connection lasts at most 30 days before you sign in again. Booking, rescheduling and cancelling email the attendees, so the assistant confirms the details with you first. Creating a booking is not idempotent: repeating the request books a second meeting. The plugin does not send free-form email, read other people's calendars, or process payments.

Tools

10 tools agents can invoke

Cancel a booking and notify its attendees. Cannot be undone. Two steps: the first call returns CONFIRMATION_REQUIRED with a confirmToken; show the user which booking will be cancelled, then call again with the SAME arguments plus confirmToken.
cancel_booking
Book a meeting on one of the caller's event types for an attendee. Sends the usual confirmation emails and calendar invites. Get a free start time from find_available_slots first; required booking questions come from get_event_type's bookingFields.
create_booking
Find the free start times for an event type between two dates. Returns slots grouped by date, each with start and end. Pass a slot's start (as UTC ISO 8601) to create_booking or reschedule_booking.
find_available_slots
Get one booking by UID: status, start and end, attendees, hosts, location or meeting URL, and any cancellation or rescheduling details.
get_booking
Get one event type in full: lengths, locations, booking questions (bookingFields), buffers, minimum notice, schedule and booking URL. Use it to learn which bookingFieldsResponses create_booking needs.
get_event_type
List the caller's bookings, optionally filtered by status (upcoming, past, cancelled, unconfirmed, recurring), attendee, event type or a time window. Paginated with take/skip; check pagination.hasNextPage.
list_bookings
List the caller's own event types (the bookable meeting kinds, e.g. '30 min intro'), hidden ones included, with ID, slug, title and length. Use an ID from here with find_available_slots and create_booking.
list_event_types
List the caller's availability schedules: working hours per weekday, date overrides, time zone, and which one is the default.
list_schedules
Move a booking to a new start time. Caly creates the new booking (with a new UID, returned here) and notifies attendees. Find a free time with find_available_slots, passing bookingUidToReschedule.
reschedule_booking
Return the Caly account this connection acts as: user ID, username, email, name, time zone, week start and default schedule. Call it first to learn the user's time zone before reading or booking times.
