How to Use the Acuity Scheduling MCP in LangChain

Q: How can a LangChain agent find an open slot in Acuity Scheduling?

Your agent can chain three tools. First, it calls listappointmenttypes to find the service ID. Then, it uses that ID with checkavailabilitydates and listavailabletimes to pinpoint an exact opening.

Q: Can I see my Acuity business profile with this?

Yes. The getaccount tool retrieves your main business information directly from your Acuity Scheduling account. It's a simple way to have your agent confirm which account it's connected to.

Q: What's the best way to handle multiple calendars in Acuity Scheduling with LangChain?

Use the listcalendars tool. A LangChain agent can fetch all calendars, letting the user choose one. The agent then uses that calendar's ID for subsequent actions, like checking availability.

Build agents that manage your Acuity calendar. A natural fit for LangChain's sequential tool-use and ReAct logic.

Chain Acuity tools together

Create agents that reason through multi-step scheduling tasks. Your agent can start by calling `list_appointment_types` to see what you offer, then use the output to `check_availability_dates` for a specific service. It’s a sequence that just makes sense. Once a date is picked, the agent can call `list_available_times` to get the final list of open slots. Each step informs the next. That's how you build a LangChain agent that doesn't just fetch data, but actually assists with the entire booking discovery process, from service selection to finding the perfect time.

Get a clear view of your business

Use this MCP Server to feed real-time business data into your chains. An agent can `list_appointments` for the last quarter and `list_calendars` to see which team members are busiest. It gets you the raw numbers you need for reports. Combine these tools to answer specific questions. For example, you could build a chain that pulls all appointments for a specific `appointmentTypeID`, giving you a clear view of how popular a certain service is. It's direct data access, ready for analysis.

Manage your service catalog

Your agent gets direct access to what your business sells. The `list_products` tool pulls in any gift certificates or items you offer alongside appointments. The `list_classes` tool shows all your group sessions, including their schedules and current enrollment. This isn't just about reading data. A smart agent can use this info to answer user questions correctly. When someone asks about a class, your agent can check `list_classes` to see if it's full before suggesting it. It makes your agent genuinely helpful.

Setup guide

Set up Acuity Scheduling MCP in LangChain

Prerequisites

Python 3.10+ installed
langchain-mcp-adapters + langgraph packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install langchain-mcp-adapters langgraph langchain-openai. The MCP adapters package converts MCP tools into native LangChain BaseTool objects.
2

Connect via HTTP transport
Use MultiServerMCPClient with "transport": "http" pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create a ReAct agent
Pass the discovered tools to create_react_agent() from LangGraph. The agent automatically routes Acuity Scheduling tool calls through the MCP protocol.
4

Run with any LLM
Swap ChatOpenAI for ChatAnthropic, ChatGoogleGenerativeAI, or any LangChain-compatible model. The MCP tools work identically across all providers.

agent.py

from langchain_mcp_adapters.client import MultiServerMCPClient
from langgraph.prebuilt import create_react_agent
from langchain_openai import ChatOpenAI

async with MultiServerMCPClient({
    "acuity-scheduling-mcp": {
        "transport": "http",
        "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp",
    }
}) as client:
    tools = client.get_tools()

    agent = create_react_agent(
        ChatOpenAI(model="gpt-4o"),
        tools,
    )
    result = await agent.ainvoke({
        "messages": "List recent Acuity Scheduling transactions"
    })
    print(result["messages"][-1].content)
