How to Use the Mercado Pago MCP in Vercel AI SDK

Q: Can Vercel AI SDK handle Pix payments with Mercado Pago?

Yes. The createpixpayment tool generates the QR payload. You simply pass that string to your UI to render the scan code for your customer.

Stream real-time Mercado Pago payment data directly into your Vercel AI SDK frontends for instant user feedback.

Process payments live in Vercel AI SDK

Your agent triggers `create_payment` or `create_pix_payment` and the result streams back to the UI before the user finishes typing. This eliminates waiting on backends for standard transaction confirmations. Everything happens in the browser's view. You hook the MCP response into your React components to show live QR codes or payment statuses the moment they generate.

Manage customers and cards via Vercel AI SDK

Store customer data using `create_customer` while your agent maintains state across sessions. This allows your app to pull user profiles without manual database lookups. When a user needs to update billing, the agent calls `create_card` to register new instruments. You keep the data flow tight by binding these tool results to your front-end state objects.

Reconcile transactions inside Vercel AI SDK

Use `search_payments` to pull historical records into your dashboard. Your agent parses the output to display filtered lists or specific transaction totals on demand. If a customer requests a reversal, the agent executes `refund_payment` directly from the interface. It's a closed-loop system where the user sees the confirmation immediately.

Setup guide

Set up Mercado Pago 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 Mercado Pago 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 Mercado Pago transactions",
});

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

Common questions about Mercado Pago MCP in Vercel AI SDK

Store your credentials in environment variables on your host. This MCP server handles the auth handshake, so your client code never touches raw API tokens.

Yes. The `create_pix_payment` tool generates the QR payload. You simply pass that string to your UI to render the scan code for your customer.

The server returns data as soon as the API responds. Since it follows the MCP standard, your stream-capable frontends handle the data chunks without extra configuration.

Check the tool response object for error codes. You can then prompt your agent to suggest alternative payment methods listed via `list_payment_methods`.

Your client only sees the transaction metadata returned by the API. Sensitive card details are tokenized by the payment provider, keeping PII out of your server logs.
