How to Use the CartonCloud MCP in LangChain

Q: Can LangChain trace CartonCloud tool execution?

Yes, every call to tools like getproductstock is traced automatically if you have LangSmith configured. You'll see the exact inputs, outputs, and latency for every warehouse query.

Q: How is my CartonCloud warehouse data secured?

Your logistics data, including stock levels from getproductstock and sensitive billing info from listlogisticsinvoices, runs through isolated V8 sandboxes. Vinkius handles the API authentication securely, so your raw credentials never expose themselves to the LLM or external logs.

Run multi-step logistics chains across CartonCloud warehouses directly from your LangChain agents.

Chain CartonCloud operations with LangChain

This MCP server exposes CartonCloud's inventory and shipping data directly to your ReAct agents. By calling `list_purchase_orders` and feeding that right into `get_product_stock`, your pipeline verifies inbound shipments against current warehouse capacity without manual intervention. You get full visibility into this tool-calling loop using LangSmith tracing. Every raw payload, latency spike, and token count from these logistics calls gets logged so you can debug your supply chain chains in real time.

Automate transport and billing workflows

This toolset lets your agent pull active freight data and match it to client accounts instantly. Your agent calls `list_consignments` to find outstanding deliveries, then uses `list_logistics_customers` to map those shipments to the correct billing profiles. Instead of jumping between logistics portals, you build chains that handle the grunt work. If a customer asks for their billing status, the agent pulls details via `list_logistics_invoices` and outputs a clean summary in one run.

Sync sale orders with live warehouse data

This CartonCloud MCP Server lets your agent sync sales data directly to warehouse master records. The agent runs `list_sale_orders` to spot unfulfilled orders, then executes `get_sale_order_details` to isolate the exact items that need packing. By integrating this CartonCloud MCP Server into your existing database chains, you can compare local database records against actual warehouse master data from `list_warehouse_products`. This setup flags discrepancies before they hit the dock.

Setup guide

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