How to Use the Magento (Adobe Commerce) MCP in LangChain

Chain Magento (Adobe Commerce) operations in LangChain

Feed the output of `mg.search_orders` directly into `mg.get_order` to automate invoice verification. This MCP Server lets your agent trigger a sequence of calls without manual intervention. Your chains maintain full state across steps, allowing you to link customer IDs from `mg.search_customers` to specific order lookups. Each step is traceable through your existing observability stack.

Multi-server aggregation for complex commerce tasks

Combine your Magento (Adobe Commerce) tools with external databases or vector stores using standard LangChain adapters. Your agent decides the execution order based on intermediate tool results. Use `mg.get_product` alongside your own internal pricing logic. The agent handles the logic flow while this MCP Server provides the raw commerce data.

Automated inventory sync with custom agents

Monitor stock levels by piping `mg.get_stock` results into your custom alert logic. The server translates native API responses into usable objects for your LangChain agent. Avoid manual status checks by letting the agent poll `mg.search_products` on a schedule. It processes the response and decides if a stock update is required.

Setup guide

Set up Magento (Adobe Commerce) 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 Magento (Adobe Commerce) 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({
    "magento-adobe-commerce-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 Magento (Adobe Commerce) transactions"
    })
    print(result["messages"][-1].content)
