How to Use the World Bank Countries MCP in Vercel AI SDK

Q: How do I use World Bank Countries data with the Vercel AI SDK?

You call the specific tool (like listcountries) through your configured MCP client. The result streams directly into your UI, so you're showing the user the data appearing live. You don't wait for a single block of JSON.

Q: Can I search World Bank Countries by region using Vercel AI SDK?

Yes. When you run searchregions, your agent client processes the request and streams back the location metadata. This is great for populating maps or regional filters in your frontend.

Stream World Bank Countries data instantly into your React, Next.js, or Vue UI with Vercel AI SDK.

Perplexity

Fetch country lists live in the browser.

You can call `list_countries` to populate a dropdown menu as the user types. This is perfect for making your app feel fast. The result streams right into your React component, so you don't need that annoying loading spinner. It feels instant.

Search World Bank Countries by income level.

Need to filter data based on economic status? Use `search_income_levels` to narrow down results (like HIC or LIC). This lets you build complex filtering mechanisms. Your agent handles the API call, and your SDK client streams back only the relevant country records. The UI updates in real time.

Get geographic regions for World Bank Countries.

`search_regions` helps you classify countries by their location (e.g., Latin America or Europe). It gives you the metadata needed to group data points. Because this is an Edge Function compatible MCP Server, calling `search_regions` keeps your client code lightweight and fast.

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.

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 Countries transactions",
});

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