Perplexity

Multi-step data reasoning

The `get_indicator_data` tool lets your agent get any World Bank indicator for a specific country or region. You can build chains where the output of one call determines the next step, for instance: calling `get_gdp` first, then using that GDP figure to determine which second-level metric like `get_fdi` should be retrieved. This means you aren't just fetching numbers; you're building a flow. The agent decides the sequence and calls tools like `get_exports`, followed by `get_external_debt`, completing a multi-stage economic analysis.

Economic health metrics

You can run complex comparisons across multiple indicators simultaneously. Use `get_gdp` to get the Gross Domestic Product, and then chain it with `get_gini_index` to assess inequality within that economy. This gives you a full picture of economic structure. Need to check resource allocation? You pair `get_health_expenditure` (as % of GDP) with `get_research_dev_expenditure`. The resulting chain provides instant, comparative data points for policy reports.

Global demographic tracking

The server exposes tools like `get_population_growth` and `get_life_expectancy`, allowing your agent to track population shifts over time. You can construct a chain that first checks the total population using `get_total_population`, then follows up with `get_infant_mortality` for deeper insights. This is perfect for demographic modeling. Your multi-step pipeline handles inputs like country codes (e.g., BRA) and determines which tools, such as `get_literacy_rate` or `get_poverty`, are most relevant to the current analysis.

Setup guide

Set up World Bank Full Access 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 Full Access 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-full-access-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 Full Access transactions"
    })
    print(result["messages"][-1].content)

Common questions about World Bank Full Access MCP in LangChain

You build it as a sequence of actions. The agent calls one tool, gets the result (e.g., `get_inflation`), and then passes that finding—maybe a high inflation rate—as input to decide whether to call another tool like `get_external_debt`.

It accesses nearly every major indicator: GDP, poverty rates (`get_poverty`), electricity access (`get_electricity_access`), and labor force metrics. It's a massive dataset ready for complex chaining.

Yes, the `get_indicator_data` tool accepts country codes or region identifiers. You can run comparative analyses across multiple regions within a single agent workflow.

Absolutely. The tools let you compare `get_health_expenditure` and `get_renewable_energy`, giving you immediate data on how countries are investing in sustainability and public health.

This server touches economic indicators, including Gross Domestic Product (GDP), total external debt stocks (% of GNI), and population metrics like the total labor force count.
