Acuity Scheduling MCP by usefulapi

List existing group class time slots in a month. To offer a new session use acuity_offer_class (Enterprise credentials required); booking an attendee does not offer a new class. Acuity REST: GET /availability/classes.

List dates in a month that have availability for an appointment type. Acuity REST: GET /availability/dates.

List available time slots on a given date for an appointment type. Acuity REST: GET /availability/times.

CANCELS an existing appointment. This MODIFIES the calendar and, unless suppressed, may send cancellation emails. Acuity REST: PUT /appointments/{id}/cancel.

CREATES a new appointment (books a client into an existing time slot). To offer an additional group class session use acuity_offer_class; this tool books attendees. This MODIFIES the calendar and, unless suppressed, may send confirmation emails. Acuity REST: POST /appointments.

CREATES a new client record in the account's client list. This ADDS data to the account. Acuity REST: POST /clients.

Get a single appointment by its id. Acuity REST: GET /appointments/{id}.

Get the authenticated Acuity account's profile (name, email, timezone, plan, currency). Acuity REST: GET /me.

List the account's appointment types (services and classes), including price, duration and calendars. Acuity REST: GET /appointment-types.

List appointments scheduled on the account. For bulk contact/parent lists, use view: contacts to return only id, firstName, lastName, email, phone and datetime, without forms/formsText. Contacts view or an explicit offset returns {appointments, pagination}; follow pagination.nextOffset with identical filters until null. Pages fit below the tool output cap and can contain fewer than max rows. Offsets are connector-managed by fetching a prefix (Acuity has no documented native offset); at 10,000 appointments per filter/date window, narrow minDate/maxDate and restart at 0. Appointments may change between calls; deduplicate by id. Default full view without offset preserves the original array response. Acuity REST: GET /appointments.

List blocked-off (unavailable) time ranges on the account's calendars. Acuity REST: GET /blocks.

List the account's calendars (staff/resources appointments can be booked on). Acuity REST: GET /calendars.

List clients on the account, optionally filtered by a search string (name/email/phone). Acuity REST: GET /clients.

List the account's custom intake forms and their fields. Acuity REST: GET /forms.

List the appointment labels (colored tags) defined on the account. Acuity REST: GET /labels.

List store orders (product / package / gift-certificate purchases). Acuity REST: GET /orders.

List the account's products / packages / gift certificates for sale. Acuity REST: GET /products.

Offer one NEW session of an existing group class appointment type. Requires Acuity Enterprise API access: reconnect with the Scheduling Instance ID, Enterprise API key and optional Enterprise ID field filled. First call previews; set confirm=true only after the user approves the calendar, date and time. Creates an offering, not an attendee booking. Existing offerings are rejected, and series are excluded to avoid changing enrolled clients' schedules. Dates/times use the calendar's timezone. Acuity Enterprise: POST /information/availability/classes, with no update id.

RESCHEDULES an existing appointment to a new time (and optionally a new calendar). This MODIFIES the calendar and, unless suppressed, may send update emails. Acuity REST: PUT /appointments/{id}/reschedule.
