Automate logistics with LangChain agents

Connect your agents to `create_shipment` to generate labels without manual data entry. The agent handles the full lifecycle from address verification to booking. Your chains process `get_rates` data to pick the cheapest carrier. It turns raw logistics logic into a repeatable pipeline.

Real-time visibility in LangChain

Feed `track_package` outputs into your state graph to alert users about delays. You get immediate status updates as the agent executes each step. Use `track_multiple_packages` to handle bulk status queries. The agent parses scan history to provide human-readable summaries.

Precise address validation for LangChain

Run `validate_address` before any transaction to stop delivery errors before they happen. Your agent checks shipping data against official records. Follow up with `get_postal_code` to fix typos. This keeps your logistics data clean and ensures every package reaches the right destination.

Setup guide

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