How to Use the Geocode.xyz MCP in LangChain

Q: Can LangChain use Geocode.xyz to resolve coordinates from addresses?

Yes. You trigger the forwardgeocode tool to turn a standard address into latitude and longitude. The agent then uses these coordinates for mapping or distance calculations.

Geocode.xyz turns raw location data into structured chain inputs for your LangChain agents.

Chain address resolution in LangChain

Feed partial user input into the `autocomplete` tool to get precise location matches. You pass these results directly into subsequent chain steps without manual parsing. Your agent handles the flow, moving from a user's vague query to a specific coordinate set. It's that simple.

Extract locations from text via LangChain

Use the `geoparse` tool to identify entities in unstructured text. Your agent identifies locations, then triggers a follow-up action based on the identified coordinates. This keeps your pipeline moving. You avoid the overhead of custom regex or brittle string matching logic.

Verify IP data within LangChain

The `ip_geolocation` tool provides immediate geographic context for incoming requests. You pipe this data into your agent to customize responses based on the user's origin. It removes the guesswork from localization. Your agent knows exactly where the request originates before it processes the next task.

Setup guide

Set up Geocode.xyz 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 Geocode.xyz 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({
    "geocodexyz-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 Geocode.xyz transactions"
    })
    print(result["messages"][-1].content)

Common questions about Geocode.xyz MCP in LangChain

You use the MultiServerMCPClient to connect the server. Once the client is initialized, you call get_tools and pass the output directly into your agent's tool list.

Yes. You trigger the `forward_geocode` tool to turn a standard address into latitude and longitude. The agent then uses these coordinates for mapping or distance calculations.

LangSmith tracing captures the failed output immediately. You can inspect the specific tool input and error response to debug your chain logic.

The server manages individual requests per tool call. You can loop through your data in the agent's logic to handle larger batches.

Your agent only transmits the specific address or IP string required for the lookup. The connection is ephemeral and handled via your endpoint token.
