How to Use the Linnworks (E-commerce Ops) MCP in LangChain

Q: How do I connect Linnworks (E-commerce Ops) to my LangChain agent?

You install langchain-mcp-adapters and initialize the MultiServerMCPClient with the server URL. Then, call client.gettools() and pass them directly to your agent's tool list.

Q: Can LangChain handle multi-warehouse inventory updates via Linnworks (E-commerce Ops)?

Yes, your agent chains listlocations to identify warehouse IDs and then runs getstocklevel to pull specific SKU numbers. LangGraph manages the state between these calls so the correct warehouse data is used.

Get raw Linnworks data straight into your LangChain multi-step reasoning pipelines without writing API glue code.

Chain order routing with LangChain

`list_open_orders` pulls active purchases directly into your LangChain run, exposing customer addresses and item details to your agent. From there, the LLM parses the destination and immediately passes the output to `list_postal_services` to compare shipping rates. You configure this sequence using LangGraph to build a strict, multi-step execution chain powered by this MCP server. LangSmith tracks the exact latency of every single POST request, so you see precisely where the API bottlenecks occur.

Automated stock level checks

`get_stock_level` retrieves real-time quantities across your warehouse network based on the SKU returned from an active customer query. Your agent checks available, in-order, and due quantities to decide if a replenishment trigger is necessary. The model then automatically routes the output to `get_inventory_item` to grab supplier details and weight metrics. LangChain handles this data handoff without manual parsing, ensuring your stock levels match across all physical locations.

Custom RPC execution for fallback endpoints

`execute_custom_rpc` acts as a fallback tool when your LangChain agent needs to hit specialized Linnworks endpoints not covered by standard tools. It executes raw POST requests to paths like `/api/Inventory/GetInventoryItemTitles` using the exact parameters your agent generates. Integrating this custom tool into your agent's toolkit means you don't hit a wall when Linnworks updates its API schema. This MCP tool ensures your automated workflows remain functional even during complex channel updates.

Setup guide

Set up Linnworks (E-commerce Ops) 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 Linnworks (E-commerce Ops) 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({
    "linnworks-e-commerce-ops-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 Linnworks (E-commerce Ops) transactions"
    })
    print(result["messages"][-1].content)

Yes, your agent chains `list_locations` to identify warehouse IDs and then runs `get_stock_level` to pull specific SKU numbers. LangGraph manages the state between these calls so the correct warehouse data is used.

You use LangSmith tracing to inspect every tool call made by this MCP Server. It logs the exact execution time for POST requests like `list_open_orders` and `list_returns`.

The LangChain agent catches the error and can use fallback logic to retry or alert your team. You can also configure the agent to call `execute_custom_rpc` if a specific endpoint returns a timeout.

Your customer addresses and order histories never touch external servers. All API requests run inside an isolated, zero-trust V8 sandbox that destroys itself immediately after execution.
