Chain Demographic Data with LangChain

The `predict_age` tool feeds directly into your LangChain ReAct agents. When your agent processes a customer support ticket, it pulls the user's first name and requests an age estimate. That output becomes the input for the next step in your sequence. A routing agent looks at the predicted age and decides whether to send the ticket to the Gen Z support queue or the senior assistance desk.

Process User Lists in Bulk

Analyzing a massive CRM dump requires the `predict_age_batch` tool. Your LangChain script grabs an array of first names from a database node and passes them to the Agify MCP Server in one shot. You get back an array of predicted ages without looping through individual API calls. LangSmith tracks the exact latency and token usage for this batch operation, so you know exactly how much time the step took.

Localize Name Analysis

Names mean different things in different places. The `predict_age` tool accepts an optional country code parameter to narrow down the demographic context. An agent parsing a French mailing list passes "FR" alongside the name "Jean". The model returns the expected age for a French Jean, completely ignoring how old an American Jean might be.

Setup guide

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

Common questions about Agify MCP in LangChain

Install `langchain-mcp-adapters`. Use `MultiServerMCPClient` with your Vinkius endpoint URL and pass the resulting tools to your ReAct agent.

Yes. LangSmith automatically traces every call to the server. You see the exact input names, the predicted age outputs, and the request latency.

Vinkius manages the connection, but you should use the batch tool for large lists. Sending an array of names in one call prevents your ReAct agent from hitting API thresholds.

The tool returns an estimate based on historical name data. Your chain logic should treat this as a probabilistic input, not a strict fact, when routing workflows.

The sandbox isolates every request. First names and country codes pass through an ephemeral V8 Isolate that executes the call and immediately destroys the memory state.
