Acuity Scheduling MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Acuity Scheduling and the rest of your systems. It gives your agent 33 Acuity Scheduling actions (22 reads, 7 writes and 4 that wait for a confirmation) and holds the Acuity Scheduling credential itself, so the agent never does. It paces Acuity Scheduling's limits and records every call.

Set up

Connect Acuity Scheduling in three steps.

01
Add actionlake to Claude.
Run the command once in Claude Code; its consent page can create a free sandbox: 100,000 calls a month, no card. In the Claude app, add a custom connector with the URL below and paste your key on the consent page. Creating a new sandbox from the Claude app is not yet tested by us.

02
Connect Acuity Scheduling.
Username and secret. No consent screen: your agent can connect it for you, but the key then passes through your chat. To keep it out of the model's context, paste it in the console instead. actionlake stores what you paste write-only, sealed under your tenant's key.

- api_keyAcuity API key (Integrations > API > View credentials)
```
account { op: "connections.requirements", service: "acuity_scheduling" }
# free: exactly what to paste, and what is found for you
```

Make the first call. Check before a write.

Ask in plain words; Claude picks the action. Before anything changes, check validates the call and prices it, for free.

Top actions

The Acuity Scheduling API, shaped for agents.

The ids your agent types, what each does, and the one name it shares with other systems. 14 of Acuity Scheduling's 14 action names are shared with at least one other connector, so an agent learns them once.

Across your systems

Acuity Scheduling, joined to the rest of your business.

One ask fetches from Acuity Scheduling and another system, joins the rows on the same customer on our side, and hands your agent the answer, not every row.

Governance for Acuity Scheduling

Destructive actions wait for a yes.

4 Acuity Scheduling actions are destructive. These are all of them:

Delete a clientacuity_scheduling.clients.delete
Cancel an appointmentacuity_scheduling.appointments.cancel
Delete a blockacuity_scheduling.blocks.delete
Delete a certificateacuity_scheduling.certificates.delete

A destructive action runs only with confirm: true. Under the human policy the agent cannot confirm for itself: the run stops until a named person approves, in the console or from a signed link in an email. The cap on a key is refused before the call is sent, never after.

doacuity_scheduling.clients.deleteconfirm_policy: human

Cost

What Acuity Scheduling costs on actionlake.

Questions

The Acuity Scheduling MCP server, answered.

Is there an Acuity Scheduling MCP server for Claude?

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 33 Acuity Scheduling actions across appointments, availability, blocks and certificates, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Acuity Scheduling.

What do I need to connect Acuity Scheduling?

Acuity numeric User ID (Integrations > API > View credentials) and Acuity API key (Integrations > API > View credentials). The free call account { op: "connections.requirements", service: "acuity_scheduling" } lists exactly what to paste.

Can an AI agent delete or change things in Acuity Scheduling?

Only if its key allows it, and only with an explicit confirmation. 4 Acuity Scheduling actions are destructive, including delete a client, cancel an appointment and delete a block. Each runs only with confirm: true. Under the human confirm policy, or an approval rule on the key, the run waits until a named person approves it.

Will an AI agent use up my Acuity Scheduling API limit?

actionlake paces every call to the limits in the Acuity Scheduling service file: 10 calls a second per connection. Repeated reads are answered from cache (21 Acuity Scheduling actions can be), which never reaches Acuity Scheduling.

What does an Acuity Scheduling action cost?

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (33 Acuity Scheduling actions page). Cache hits, searches, dry runs and calls Acuity Scheduling refused with 401, 403, 429 or a 5xx are free. The Free plan includes 100,000 calls a month with no card. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000.

Which Acuity Scheduling API does it cover?

The Acuity Scheduling API v1 (reference v1.1) at acuityscheduling.com/api/v1. It is built from Acuity Scheduling's documentation as read on 23 October 2026. 33 actions in 15 areas, each one in the signed service file (version 1.0.0).

Can I combine Acuity Scheduling with my other systems?

Yes. ask joins Acuity Scheduling to HaloPSA or NetSuite on the same customer and returns the answer rather than every row. Acuity Scheduling maps crm.contact, which 192 other connectors also map.

Does actionlake keep my Acuity Scheduling data, and where?

actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to 10 minutes, and a write clears the reads it affects. Each run's request and response is kept, sealed, for your plan's trace window: 1 day on Free, 3 days on Starter, 7 days on Pro, 14 days on Team, 30 days on Business and 30 days on Enterprise. Your Acuity Scheduling credential is sealed under your tenant's key, never logged and never returned. Your traffic is not used to train models.

Which AI clients can use it?

Claude Code, tested by us end to end, and the Claude app as a custom connector, tested by us with an existing key. Other MCP clients that support remote servers over Streamable HTTP (MCP revisions 2025-06-18 and 2025-11-25) and OAuth dynamic client registration, or a bearer header, should connect the same way; we have not tested them. Or plain REST, under the same action names.
