How to Use the Coppel MCP in LangChain

Q: Can LangChain agents handle Coppel weekly payment plans?

Yes. Your LangChain agent can check eligibility with getcustomercredit and then structure the createorder payload to select weekly payment plans for qualified customers.

Q: What happens if a product is out of stock?

The searchproducts tool returns current availability. Your agent reads this status and can suggest alternative products from listproducts in the same category.

Chain Coppel Credit Checks with LangChain

This Coppel MCP Server exposes tools like `get_customer_credit` and `list_payments` directly to your LangChain reasoning loops. Your LangChain agent grabs the customer ID, checks their Coppel credit, and determines if they qualify for weekly payment plans before drafting an invoice. Because this runs inside LangChain, you can pipe these Coppel credit outputs directly into a decision chain. If the Coppel credit check fails, your LangChain chain automatically pivots to cash-only options. Use LangSmith to track every Coppel tool execution and debug exactly where a credit check stalled.

Automated Inventory Sourcing in LangChain

You can query Coppel stock and place orders instantly in LangChain using MCP tools like `search_products`, `get_product`, and `create_order`. The LangChain agent matches user queries against the Coppel catalog, grabs the correct product IDs, and submits the order. LangChain handles this Coppel sequence by feeding the output of your product search directly into the Coppel order creation prompt. You don't write glue code to pass Coppel variables between API calls because LangChain handles the variable handoff.

Locate Mexican Outlets for LangChain Agents

The Coppel server uses `list_stores` and `get_store` to filter physical retail locations by Mexican state for your LangChain agent. Your LangChain agent can find the closest Coppel physical branch for customers who prefer to pay their weekly installments in cash. This integrates into your LangChain agent's routing logic. If a customer chooses Coppel store pickup, the LangChain chain calls these tools to find the nearest Jalisco or CDMX location and appends the store address to the Coppel order draft.

Setup guide

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