Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 18

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

acuity

acuity_availability_classes

List group class time slots (for class-type appointment types) in a month. Acuity REST: GET /availability/classes.

acuity_availability_dates

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

acuity_availability_times

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

acuity_cancel_appointment

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

acuity_create_appointment

CREATES a new appointment (books a client into a time slot). This MODIFIES the calendar and, unless suppressed, may send confirmation emails. Acuity REST: POST /appointments.

acuity_create_client

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

acuity_get_appointment

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

acuity_get_me

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

acuity_list_appointment_types

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

acuity_list_appointments

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.

acuity_list_blocks

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

acuity_list_calendars

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

acuity_list_clients

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

acuity_list_forms

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

acuity_list_labels

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

acuity_list_orders

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

acuity_list_products

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

acuity_reschedule_appointment

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.
