Stream name analysis live to your React UI

The `predict_nationality` tool identifies the most likely country of origin for any surname you pass to it. Because you are using this with the Vercel AI SDK, the resulting probability scores stream straight to your user's screen instead of hiding behind a loading spinner. This name-prediction setup works on Edge Functions without adding latency to your Next.js routes. Your UI updates as the country probability data arrives, letting users see name-based regional insights immediately during registration.

Clean up form routing with this MCP Server

The `predict_nationality` tool analyzes surname strings to output structured country codes and probability metrics. This MCP Server integration allows your edge-rendered Vercel AI SDK forms to instantly route users based on name-origin predictions. You don't need to build complex geolocation lookups when you can predict nationality directly from a name string. The Vercel AI SDK client processes the name string on the fly, feeding the raw JSON country codes directly into your React state.

Single-token edge deployments for your team

The `predict_nationality` tool runs inside a secure V8 isolate managed by Vinkius, requiring only a single endpoint token. This means your Vercel AI SDK setup does not need to store raw Nationalize API keys in your client-side environment variables. You initialize the Vercel AI SDK client, fetch the `predict_nationality` tool, and close the connection when the edge execution finishes. This design keeps your Next.js frontend lightweight and prevents Nationalize API key exposure on the client side.

Setup guide

Set up Nationalize 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 Nationalize 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 Nationalize transactions",
});

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

Common questions about Nationalize MCP in Vercel AI SDK

Install the required packages using npm, then initialize the client with your Vinkius HTTP endpoint. Pass the tools directly into the streamText function and make sure to close the client connection when done.

The underlying database matches name strings against localized demographic records, which are far more distinct for surnames. Your Vercel AI SDK client will get much more reliable data if you feed it last names.

Yes, the integration is fully compatible with Edge Functions. The Vercel AI SDK connects to the server over a lightweight HTTP transport that does not use Node.js-specific libraries.

Vinkius manages the connection to the Nationalize API behind the scenes. Your client only communicates with the sandbox endpoint, which handles connection pooling and credential management.

The server only passes the specific name string to the Nationalize API to run the prediction. Vinkius executes this in an ephemeral sandbox, meaning no personal names are stored or logged after the request completes.
