How to Use the Nuvei MCP in Vercel AI SDK

Q: How do I process a Nuvei payment in Vercel AI SDK?

Pass the tool definitions from this MCP server into your streamText configuration. Once the agent invokes createpayment, the result streams back to your frontend.

Q: Can I use Nuvei to store card tokens in Vercel AI SDK?

Yes. Use createcardtoken to generate a secure reference. You then store that token in your database for future checkouts.

Q: Does Nuvei support partial refunds via Vercel AI SDK?

It does. Call refundpayment with the specific transaction ID and the amount you want to return to the customer.

Stream real-time Nuvei payment data directly into your Vercel AI SDK frontends for live transaction tracking.

Live payment processing with Vercel AI SDK

Trigger `create_payment` directly from your UI components to authorize charges. Your users see the transaction status stream into the interface as the agent executes the call. This bypasses traditional loading states. The AI client handles the handshake, letting you push payment outcomes to the browser instantly.

Secure card vaulting in your MCP Server

Convert sensitive card data into reusable references using `create_card_token`. Store these safely in your vault without touching raw credit card numbers. Updating existing records is just as simple. Use `update_token` to modify expiry dates or billing metadata without requiring the user to re-enter their card.

Automated payment lifecycle management

Fetch transaction histories using `get_transactions` to display up-to-date reports. Use `get_payment` to verify if a pending charge cleared before updating your database. Handle exceptions by calling `void_payment` for canceled orders or `refund_payment` for partial returns. Every action maps to a clear, actionable state in your application.

Setup guide

Set up Nuvei 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 Nuvei 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 Nuvei transactions",
});

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