Build multi-step shipping chains in LangChain

This J&T Express Malaysia MCP server lets you chain geographical tools like `list_provinces` directly inside your LangChain workflows. You can narrow down the Malaysian delivery area with `list_cities` before calculating the final shipping cost. LangSmith traces the entire execution to show you exactly how these J&T Express Malaysia tools ran. You get clear visibility into every Malaysian shipping rate calculation inside your LangChain graph.

Automated order creation and waybill retrieval

Running `create_order` initiates the entire J&T Express Malaysia fulfillment loop when a customer purchases an item inside your LangChain application. The agent triggers the booking and immediately grabs the Malaysian shipping label link via `get_waybill_image`. If a customer changes their mind, your LangChain agent can call `cancel_order` to stop the J&T Express Malaysia shipment before the courier picks it up. You don't have to build custom Malaysian API integrations for each edge case.

Real-time package tracking and status updates

Executing `track_order` keeps your LangChain users updated by checking the live status of their J&T Express Malaysia delivery. The agent parses the raw Malaysian tracking milestones and explains the current status in plain English. You can combine this tracking with `get_order_details` to verify the Malaysian recipient's address inside your LangChain support pipeline. It keeps your J&T Express Malaysia customer support running without human intervention.

Setup guide

Set up J&T Express Malaysia 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 J&T Express Malaysia 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({
    "jt-express-malaysia-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 J&T Express Malaysia transactions"
    })
    print(result["messages"][-1].content)
