How to Use the TomTom Alternative MCP in LangChain

Q: How does TomTom Alternative help with geocoding in LangChain?

You simply call the geocode tool. It takes a raw address string and converts it into precise geographic coordinates (latitude/longitude). The resulting coordinate pair can then be passed directly to any routing function.

Q: What data does TomTom Alternative provide for advanced routing in LangChain?

The calculateadvancedroute tool calculates routes between points while supporting specific waypoints and allowing you to specify if certain vignettes must be avoided. It goes beyond simple A-to-B pathing.

Q: Does TomTom Alternative support map visualization for AutoGen agents?

While this server works with all clients, the getmaptile tool allows you to retrieve the URL needed for a visual tile image. This is useful when an agent needs to show the user exactly what area it's talking about.

Q: What data does TomTom Alternative touch regarding traffic incidents?

This MCP Server touches real-time traffic incident and flow information. The gettrafficincidents tool provides this live data, letting your agent know if a calculated route is viable.

Plan Complex Routes via MCP Server

The agent can first use `fuzzy_search` to find a POI name, then call `geocode` on that result. Finally, it uses the resulting coordinates to run `calculate_advanced_route`. This builds complex chains where one tool's output drives the next step. It handles avoiding specific areas or vignettes when calculating these routes. You don't just get a route; you get a multi-step plan that respects real-world constraints.

Check Real-Time Traffic Conditions

Your agent needs up-to-the-second data? Just invoke `get_traffic_incidents`. It gives live traffic flow details and incident reports for a given area. This is crucial when the fastest calculated path isn't actually clear to drive on. The results of this call are immediately available in the agent’s memory, allowing it to adjust its routing logic mid-chain.

Get Map Visual Data

Need a map image for display? Use `get_map_tile`. This tool returns the direct URL needed to pull the specific map tile. It's fast and lightweight, making it perfect for injecting visual context into your agent’s final output. You can call this function after any coordinate-based operation (like `geocode` or `calculate_route`) to visually confirm the data points.

Setup guide

Set up TomTom Alternative 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 TomTom Alternative 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({
    "tomtom-alternative-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 TomTom Alternative transactions"
    })
    print(result["messages"][-1].content)

This MCP Server touches real-time **traffic incident and flow information**. The `get_traffic_incidents` tool provides this live data, letting your agent know if a calculated route is viable.

Since the client supports stateless operations by default, you'll need to use `client.session()` to maintain persistent context across multiple tool calls or agent interactions.
