How to Use the Picktime MCP in LangChain

Q: Can LangChain use Picktime to handle cancellations?

Yes. Your agent can call cancelbooking by passing the required reservation ID. It verifies the booking details first to ensure the correct appointment is removed.

Q: Does Picktime work with LangChain for multi-location businesses?

Absolutely. Use listlocations to detect which branch the user is inquiring about. This allows the agent to scope all subsequent tool calls correctly.

Q: Is there a way to check service availability in LangChain?

Use getavailability to pull real-time slots. The tool processes existing bookings and buffers, giving your agent the data it needs to suggest times.

Build complex scheduling chains in LangChain. Use the Picktime MCP Server to turn raw booking data into automated action sequences.

Chain booking actions in LangChain

Connect `list_services` to `get_availability` to build automated booking pipelines. Your agent evaluates the service list first, then queries open slots for a specific date. This workflow ensures your agent only proposes valid times. It eliminates the need for hardcoded logic when checking staff schedules through `list_staff`.

Automate scheduling via MCP Server

Inject the Picktime MCP Server tools directly into your LangChain agent. Your agent uses `get_booking_details` to verify client info before executing a `cancel_booking` command. This creates a reliable loop for managing appointments. Every step is traceable, allowing you to monitor how the agent handles customer requests.

Manage locations with precision

Use `list_locations` to map out your business branches before running operations. The agent identifies the correct location ID, preventing cross-branch booking errors. Once the location is set, tools like `list_classes` provide accurate session data. This keeps your scheduling logic clean and branch-specific.

Setup guide

Set up Picktime 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 Picktime 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({
    "picktime-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 Picktime transactions"
    })
    print(result["messages"][-1].content)
