How to connect Acuity Scheduling to Claude Code, ChatGPT and any AI agent

Yes, Claude, ChatGPT and other AI agents can work in your Acuity Scheduling account. Acuity Scheduling has developer API documentation, but no official app in the ChatGPT or Claude directories. Cotlet.dev connects your own signed-in Acuity Scheduling account to any AI agent, so you can ask in plain words and the AI lists your appointments and finds open times for you.

What you can ask

List all appointments for next Tuesday with client names, times and appointment types.

Is there an open 60-minute slot with Dr. Patel on Thursday afternoon?

Show me every free time for a Deep Tissue Massage between November 16 and 20.

Which appointments does Maria Lopez have this month, and which ones are still upcoming?

Which calendars have nothing booked on Saturday morning? List the open times from 9 am to noon.

Related MCP server: appointy-mcp

Connect in 2 minutes

Get your API key at https://cotlet.dev/app and export it as COTLET_API_KEY.

Claude Code

claude mcp add --transport http cotlet https://cotlet.dev/mcp/v1 --header "Authorization: Bearer $COTLET_API_KEY"

ChatGPT

Settings → Apps → add connector URL https://cotlet.dev/mcp/v1, then sign in with Cotlet.dev. No API key needed.

Cursor

Copy .cursor/mcp.json from this repo into your project:

{
  "mcpServers": {
    "cotlet": {
      "url": "https://cotlet.dev/mcp/v1",
      "headers": {
        "Authorization": "Bearer ${COTLET_API_KEY}"
      }
    }
  }
}

Run it locally (stdio)

This repo is a real MCP server. It speaks MCP over stdio, lists its Acuity Scheduling tools without any key, and forwards every tool call to the hosted Cotlet.dev server. The hosted URL above stays the recommended way. Use this when your client only starts local servers.

{"mcpServers":{"acuity-scheduling":{"command":"uvx","args":["acuity-scheduling-mcp"],"env":{"COTLET_API_KEY":"your-key"}}}}

Or with Docker:

docker build -t acuity-scheduling-mcp .
docker run -i --rm -e COTLET_API_KEY acuity-scheduling-mcp

Tools: acuity_scheduling_guide, acuity_scheduling_status, acuity_scheduling_open, acuity_scheduling_read, acuity_scheduling_click, acuity_scheduling_type, acuity_scheduling_close. Without COTLET_API_KEY a tool call answers: "Set COTLET_API_KEY. Get a key at https://cotlet.dev/app".

Command line

Python 3.10+, nothing else to install. From PyPI:

pip install acuity-scheduling-mcp        # or run it once: uvx acuity-scheduling-mcp connect
acuity-scheduling-mcp connect

Or straight from this repo:

export COTLET_API_KEY="your-key"
python3 acuity_scheduling_agent.py connect   # ready config for Claude Code, Cursor, ChatGPT
python3 acuity_scheduling_agent.py status    # is Acuity Scheduling ready in your Cotlet.dev account
python3 acuity_scheduling_agent.py guide     # Acuity Scheduling screens and sign-in link
python3 acuity_scheduling_agent.py read      # open Acuity Scheduling, read the page, close the browser
python3 acuity_scheduling_agent.py tools     # list Cotlet.dev tools
python3 acuity_scheduling_agent.py serve     # start the stdio MCP server (same as no argument)

Questions from Acuity Scheduling users

Does Acuity Scheduling have an API?

Yes. Acuity Scheduling has a REST API, but API access comes with the Premium plan, so Starter and Standard accounts have no API key. Cotlet.dev works in your own signed-in Acuity Scheduling account, so your AI agent lists appointments and checks availability without an API key.

How do I connect Acuity Scheduling to ChatGPT?

Add Cotlet.dev as an app in ChatGPT (Settings → Apps, connector URL https://cotlet.dev/mcp/v1), sign in to Acuity Scheduling once in your Cotlet.dev Cloud Browser, and ask ChatGPT in plain words. No code and no Acuity Scheduling API key.

Is there a way to use Claude with Acuity Scheduling?

Yes. In Claude Code run the one-line claude mcp add command above; in the Claude app add https://cotlet.dev/mcp/v1 as a custom connector. Claude then works in your own Acuity Scheduling account.

Is there an Acuity Scheduling MCP server?

Acuity Scheduling has no official MCP server. Cotlet.dev is a hosted MCP server that works in Acuity Scheduling for you, 24/7, with Claude, ChatGPT, Cursor, Codex, n8n, Make and Zapier.
