Perplexity

Analyze inequality metrics instantly.

The `get_gini_index` tool pulls the Gini coefficient, letting you measure economic disparity across regions. You can feed this result into a subsequent step to compare it against poverty levels. This allows your agent to build a narrative that goes beyond simple data points—it shows *how* inequality relates to population health and development.

Track demographic shifts over time.

Use `get_population_growth` when you need the annual percentage change for any given area. This measurement is crucial for forecasting resource needs. Your agent can compare growth rates against social indicators, figuring out if a region's infrastructure keeps pace with its population boom.

Get total population figures quickly.

The `get_total_population` tool gives you the current, overall count for any country. It’s the foundation of almost every analysis. After getting the total headcount, your agent can chain this figure with data from `get_poverty` to calculate a precise density metric—a full picture of resource strain.

Setup guide

Set up World Bank Population 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 World Bank Population 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({
    "world-bank-population-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 World Bank Population transactions"
    })
    print(result["messages"][-1].content)
