How to Use the TurfHop MCP in LangChain

Q: How does TurfHop integrate into LangChain chains?

Your agent treats every MCP tool call—like running getjob or listcustomers—as a discrete step. The output data from one function becomes the input for the next tool in your chain.

Q: How do I verify current product offerings using TurfHop with LangChain?

You simply include listproducts in your agent's tool list. The resulting JSON array provides all available services and products, allowing the rest of your chain to make decisions based on that data.

Q: What happens if I need to update a customer record using TurfHop with LangChain?

You call updatecustomer and pass the necessary ID and new JSON payload. The MCP Server handles validating the existing customer entry before applying the changes.

Perplexity

Automate job creation and billing cycles

Your agent can manage a client interaction from start to finish. First, it checks for existing details with `get_customer`. If the customer is new, it calls `create_customer` before proceeding. After confirming the customer record, your agent uses the necessary parameters to call `create_job`, setting up service work. It can then use this job ID to retrieve or even calculate a quote using `list_quotes`.

Maintain accurate client records

Handling updates is just as important as creating new data points. If customer details change, you'll call `update_customer`. Similarly, if the scope of work changes mid-project, your agent calls `update_job` to reflect those changes. This ability ensures that every interaction with the MCP Server keeps the client records current and accurate for billing purposes.

List and aggregate business data

You don't always need an action; sometimes you just need to see what's going on. The agent can list all accounts using `list_customers` or pull a full history of completed work via `list_jobs`. It also allows listing historical financial data with `list_invoices`, giving your chain the necessary context for downstream calculations.

Setup guide

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