How to Use the Baidu Map Web Service API MCP in LangChain

Q: How do I add the Baidu Map Web Service API MCP server to my LangChain agent?

Install langchain-mcp-adapters and langgraph via pip. Initialize the MultiServerMCPClient with the Vinkius URL, call gettools(), and pass those tools directly to your agent constructor.

Q: Can I use the Baidu Map Web Service API with LangChain to run POI searches?

Yes, you can run poisearch directly within your LangChain chains to fetch Chinese business listings. The agent can then pipe these results into other tools to build a local discovery workflow.

Q: How does LangChain handle coordinate data from the Baidu Map Web Service API?

LangChain agents process the coordinates returned by geocoding as standard tool outputs. You can easily pass these latitude and longitude pairs into subsequent chain links like reversegeocoding.

Q: Can I combine this mapping tool with other LangChain integrations?

Yes, you can take the output from getbusinessarea and feed it into a vector database or a local LLM chain. This lets you generate localized marketing copy for specific Beijing districts using real-world map data.

Q: How does this server handle the privacy of my users' IP addresses?

When your LangChain agent calls iplocation through Vinkius, the IP address is sent directly to Baidu's API to resolve the location. We run the server in a secure sandbox and do not log or store these IP addresses or coordinates after the tool execution finishes.

Connect the Baidu Map MCP Server to your LangChain pipelines to chain routing and geocoding across China.

Chaining Chinese Transit Routes in LangChain

Your LangChain agent can now plot precise paths across China by using `direction_transit` and other routing tools. Feed the output of `ip_location` directly into `direction_transit` to map out a user's commute, then chain `get_suggestion` to recommend nearby stops. Because this is LangChain, every step of the journey is tracked in LangSmith. You see exactly how the agent handled the coordinates returned by `geocoding` before passing them to the driving tool.

Dynamic POI Discovery and Geocoding

The `poi_search` tool lets your agent run local business queries directly inside your chains. Let your LangChain agent resolve exact street addresses in Chinese cities by feeding those search results into `reverse_geocoding`. This MCP server exposes raw Baidu Map data directly to your ReAct loops. The agent evaluates the business districts using `get_business_area` and decides the next API call based on real-time geographical context.

Comparing Travel Modes with LangGraph

The `direction_driving` tool allows your agent to compare travel modes and calculate driving times. Your LangChain agent calls `direction_driving` and `direction_riding` simultaneously, analyzes the latency and distance, and picks the fastest route for the user. With the `direction_walking` tool integrated into your state graph, the agent can fallback to foot paths if transit schedules don't align. You get a reliable decision tree powered by actual Chinese mapping data.

Setup guide

Set up Baidu Map Web Service API 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 Baidu Map Web Service API 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({
    "baidu-map-web-service-api-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 Baidu Map Web Service API transactions"
    })
    print(result["messages"][-1].content)
