How to Use the Kelkoo MCP in Vercel AI SDK

Q: How do I use the Vercel AI SDK to search Kelkoo for a specific product?

Your agent just needs to call the searchoffers tool. Pass it a country code and your keyword, and the Vercel AI SDK will stream the results directly into your UI components.

Q: Can my Vercel AI SDK app show coupons from Kelkoo?

Yes. The searchcoupons tool is designed for this. You can have your agent search for coupons related to a product or merchant and stream them into your frontend.

Q: What's the best way to get all Kelkoo product categories with the Vercel AI SDK?

Use the getcategorytree tool. It returns the entire hierarchical structure, which you can then use to build a dynamic navigation menu in your React or Next.js application.

Q: How do I get a list of merchants?

Call the listmerchants tool with a specific country code. It will return all the merchants Kelkoo works with in that region.

Use the Vercel AI SDK to stream Kelkoo product offers and prices directly into your React and Next.js components.

Stream Live Product Offers

The `search_offers` tool lets your agent find product deals on Kelkoo. With the Vercel AI SDK, those results don't wait for a loading spinner. They stream directly into your UI, so the user sees prices and merchant names appearing in real-time as your agent finds them. Once an offer is selected, your agent can call `get_offer_details` to fetch the specifics. This data also streams in, instantly populating the product detail page. It's how you build e-commerce frontends that feel incredibly fast and responsive.

Create Dynamic Catalog UIs

You can build a complete category browser for Kelkoo's catalog. First, call `get_category_tree` to get the entire site structure and render it in a navigation sidebar. Your UI is now a live, explorable map of the Kelkoo marketplace. When a user clicks a category, your agent calls `search_offers` with that category ID. The Vercel AI SDK streams the matching products right into the main view. This makes navigating a huge product catalog feel quick and seamless.

Build Global Search with this MCP Server

This MCP server lets you operate across dozens of countries. Start by using `list_countries` to populate a country selector dropdown in your app's header. It gives you the exact country codes Kelkoo expects. When the user picks a country, that code becomes the input for all subsequent calls. Your agent can then run localized searches with `search_offers`, find local coupons with `search_coupons`, or list regional sellers using `list_merchants`. You build one app that works everywhere Kelkoo does.

Setup guide

Set up Kelkoo 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 Kelkoo 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 Kelkoo transactions",
});

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