Perplexity

Instant location lookups for Vercel AI SDK

Feed `get_country` or `get_state` results straight into your React components. Your UI renders the data as the model generates the response, keeping the interface snappy. This MCP Server pushes ISO codes and metadata directly to your edge functions. You avoid the lag of standard API calls.

Granular city data for web interfaces

Use `list_cities_by_state` to populate dropdowns or map markers. The payload arrives ready for your frontend state management. Filtering by region happens at the source. You spend less time parsing raw JSON and more time building your view.

Global cataloging via the Vercel AI SDK

Call `list_countries` to build your initial selection menus. The tool output maps cleanly to your TypeScript interfaces. Your application state stays consistent with the global registry. It handles the heavy lifting of regional lookup logic.

Setup guide

Set up CountryStateCity 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 CountryStateCity 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 CountryStateCity transactions",
});

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