Dynamic routing with LangChain

Feed the output of your agent directly into `calculate_v8_route` to get precise travel paths. You can chain these results into subsequent tasks without manual parsing. Your agent decides the best path based on live data. It handles multi-node logic by piping coordinates into `calculate_routing_matrix` automatically.

Geospatial data chains

Connect `forward_geocode` to your data sources to resolve messy user addresses into clean coordinates. This keeps your pipeline moving without stalling for human input. Use `autosuggest_query` as the first link in your chain. It narrows down user intent before the agent triggers more expensive location operations.

Real-time environment awareness

Inject `get_traffic_flow` and `get_weather_observation` into your reasoning loops. Your agent now reacts to road congestion and local conditions as they change. This data informs every decision your chain makes. It creates a feedback loop where the agent updates its plan based on the environment.

Setup guide

Set up HERE (Location & Maps) 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 HERE (Location & Maps) 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({
    "here-location-maps-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 HERE (Location & Maps) transactions"
    })
    print(result["messages"][-1].content)

Common questions about HERE (Location & Maps) MCP in LangChain

You connect them using the MCP adapter for your framework. Once registered, the tools appear as standard functions that your agent can chain together.

Yes. The agent treats each tool call as a step, allowing it to pass the output of one service directly into the next for complex workflows.

Your location data remains strictly between you and the service provider. We handle the transport, but the raw coordinates aren't stored by us.

The agent receives an error response, allowing you to build retry logic or fallback paths into your code. You control the error handling.

It does. You can integrate the tools into your stateful graphs to maintain context across multiple location queries.
