How to Use the Georef Argentina MCP in Vercel AI SDK

Q: How does this MCP Server handle user address data privacy?

Address strings passed to normalizedireccion are sent directly to the official Argentine government API. Vinkius runs the server in an ephemeral V8 isolate sandbox, meaning your raw inputs vanish the moment the request finishes.

Stream official Argentine geographic data directly into your React frontends using this MCP Server and the Vercel AI SDK.

Stream Administrative Boundaries in Vercel AI SDK

Building a location picker for users in Buenos Aires means dealing with complex administrative levels. Your Next.js app can call `get_provincias` and immediately stream the results to a dropdown component. Users see the options appear instantly instead of staring at a loading spinner while the server fetches the IDs. You get the same speed when drilling down into specific areas. Passing a province ID into `get_departamentos` or `get_municipios` returns the exact official subdivisions. Your frontend updates in real-time as the user types, keeping the UI snappy and accurate.

Fix Messy Address Inputs Live

People rarely type their street names perfectly on checkout forms. By wiring `normalize_direccion` into your input fields, the Vercel AI SDK handles the cleanup before the user even hits submit. It takes an input like "Av. Mayo 100" and returns the official street name, number, and coordinates. This prevents bad data from ever hitting your database. Instead of running batch validation jobs later, your edge functions handle the correction on the fly. The user gets a prompt to confirm the normalized address right inside the existing component.

Map Coordinates to Real Places

Dropping a pin on a map generates latitude and longitude, but your application usually needs a readable street name. The `reverse_geocoding` tool takes those raw coordinates and finds the nearest official geographic entity. It works perfectly for delivery apps where users share their current location. Because you are using this MCP Server, that translation happens automatically within your agent's reasoning loop. You can also pull specific street data using `get_vias` if you need to build custom routing interfaces. Everything streams directly into your Vue or Svelte views without extra middleware.

Setup guide

Set up Georef Argentina 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 Georef Argentina 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 Georef Argentina transactions",
});

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

Common questions about Georef Argentina MCP in Vercel AI SDK

Install the @ai-sdk/mcp package via npm. Use createMCPClient with your transport configuration, then pass the returned tools array into streamText.

The SDK itself streams the data directly to the client without native long-term caching. You should implement your own cache layer in your Next.js route handlers if you plan to hit `get_localidades` heavily.

Your stream will throw an error that you must catch in your frontend component. The official government API occasionally experiences high latency, so handling exceptions gracefully is mandatory.

It requires enough context to find a valid match in the official registry. Passing just a vague street name might return multiple options or fail entirely.

Address strings passed to `normalize_direccion` are sent directly to the official Argentine government API. Vinkius runs the server in an ephemeral V8 isolate sandbox, meaning your raw inputs vanish the moment the request finishes.
