Acuity Scheduling MCP server

What the model can do

Acuity Scheduling (Squarespace Scheduling): appointments by date, calendar, type or client, appointment types with durations, staff and location calendars, and open days and times to book. Can book, reschedule, update or cancel an appointment (telling the client only when asked), block off time on a calendar, and add or update a client. Intake forms and notes are never read.

Acts, when you ask

These change something in Acuity Scheduling. The model is told to use them only when you ask for exactly that, and each one is granted by name: per team on a shared connection, by the owner on a personal one.

• acuity_book_appointmentBook an appointment in Acuity for a client, at a time acuity_availability shows as free.
• acuity_reschedule_appointmentMove one Acuity appointment to a new time, calendar or both.
• acuity_update_appointmentChange a booked Acuity appointment's client name, email, phone, label or intake form answers, or (as admin) its notes.
• acuity_cancel_appointmentCancel one Acuity appointment.
• acuity_block_timeBlock off time on one Acuity calendar so clients cannot book it (holiday, training, lunch).
• acuity_create_clientAdd a client to the Acuity client list (no appointment is booked and the client is not contacted).
• acuity_update_clientUpdate one client in the Acuity client list, found by their current first and last name (and phone, when several share a name): new name, email…

Connect it

First connect Acuity Scheduling on Dashboard → Connections, then add Memtro to your client once. The Acuity Scheduling tools appear alongside the tools of everything else you have connected; nothing is configured per connector.

Who may use it

The key identifies the person, and the server offers that person the tools they may use everywhere else in Memtro. A shared Acuity Scheduling connection is used by the teams an administrator granted it to, tool by tool, on the Permissions page; a personal connection is used by its owner alone, and its tools that act stay off until the owner allows them. See Teams and permissions and Connectors.

Ask it like this

• › Who is booked tomorrow?
• › When is the next free slot for an initial assessment?
• › Which days next month have free time on Sarah's calendar?
• › What appointments does priya@acme.co.uk have coming up?
• › Move Tom Baker's Thursday follow-up to Friday at 10 and let him know.

Questions

Is this an official Acuity Scheduling MCP server?

No. It is Memtro's MCP server with Memtro's Acuity Scheduling connector behind it: the connector reads Acuity Scheduling through its API with the credentials you connect on Dashboard → Connections, and Acuity Scheduling publishes nothing here. The same endpoint carries every other system you connect and Memtro's memory tools.

What does it cost?

Nothing on top of Memtro. One price per organisation by its number of users, from $50 a month for up to 10 users after a 7-day free trial, with every connector, the MCP server, jobs and memory included. You bring your own model keys.

Can it change anything in Acuity Scheduling?

Only when you ask, and only what it has been granted: book an Acuity appointment for a client; reschedule an Acuity appointment; update an Acuity appointment's client details, labels or form answers; cancel an Acuity appointment; block off time on an Acuity calendar; add a client to Acuity; update an Acuity client's details. Every other tool reads, searches or lists. An administrator grants each acting tool by name per team, and a personal connection acts only after its owner allows it.

Which clients work?

Any MCP client that speaks Streamable HTTP: Claude Code, Cursor, Claude Desktop, OpenCode, Codex, Zed, Windsurf, Cline and the Anthropic and OpenAI SDKs. There is no local process to run; the server is remote and authenticated with your key.
