Perplexity

Real-time Demographic Data via MCP Server

You can stream complex demographic data directly into the client UI. For instance, when you call `mcpClient.tools().get_gini_index()`, users see the Gini index populating in real time. This eliminates that annoying loading spinner and makes your app feel fast. It's perfect for dashboards where viewing a live metric—like checking the total population using `get_total_population()`—is critical to the user experience.

Streaming Poverty Metrics with Vercel AI SDK

Build components that display poverty data as it’s retrieved. By calling `mcpClient.tools().get_poverty()`, you get the headcount ratio for $0.15 a day at 2017 prices, and the result streams immediately into your component state. This real-time flow works for any indicator. Just swap out `get_social_indicator()` to pull other World Bank data points without changing your streaming logic.

Handling Growth Indicators in a Live UI

Don't wait for the whole query to finish just to show one number. Stream population growth percentages by calling `mcpClient.tools().get_population_growth()`. The agent pulls the annual rate and streams it straight into your React component. This pattern makes any data retrieval feel snappy, whether you are checking historical trends or current figures using other indicators via `get_social_indicator()`.

Setup guide

Set up World Bank Population MCP in Vercel AI SDK

Prerequisites

Node.js 18+ and a TypeScript project
ai + @modelcontextprotocol/sdk packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies

Run npm install ai @modelcontextprotocol/sdk plus your preferred model provider (e.g. @ai-sdk/openai).
2

Create the Streamable HTTP transport

Use StreamableHTTPClientTransport with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and use tools

Call mcpClient.tools() to auto-discover all World Bank Population tools. Pass them directly to generateText() or streamText() — no manual schema definitions needed.
4

Works with any model provider

Swap openai("gpt-4o") for any AI SDK provider — Anthropic, Google, Mistral. The MCP tools work identically across all supported models.

index.ts

import { experimental_createMCPClient as createMCPClient } from "ai";
import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp";
import { generateText } from "ai";
import { openai } from "@ai-sdk/openai";

const transport = new StreamableHTTPClientTransport(
  new URL("https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp")
);

const mcpClient = await createMCPClient({ transport });
const tools = await mcpClient.tools();

const { text } = await generateText({
  model: openai("gpt-4o"),
  tools,
  prompt: "List recent World Bank Population transactions",
});

console.log(text);
await mcpClient.close();

Common questions about World Bank Population MCP in Vercel AI SDK

You expose the MCP tools to your agent client. When a user needs data, your streaming function calls `mcpClient.tools()` and handles the response stream directly in your UI code.

Yes, you just call the `get_total_population()` tool via the MCP client. The result streams back to your front end instantly, letting your users see the latest count.

This server handles various demographic statistics, including Gini coefficients (`get_gini_index`), growth rates, and poverty headcount ratios. You'll see the result type match the specific tool called.

Absolutely. The Vercel AI SDK is designed for exactly this use case, ensuring that data retrieved from the MCP server streams into your Next.js UI in real time.

It provides indicators like total population counts, annual growth rates, poverty metrics (using `get_poverty`), and general social stats via the code-based `get_social_indicator()`.
