How to Use the Commerce.js MCP in Vercel AI SDK

Q: Can Commerce.js handle real-time inventory updates in Vercel AI SDK?

Yes. You can trigger listproducts whenever the agent needs the latest stock levels. The data streams immediately to your frontend.

Q: Does Commerce.js support secure order capture in Vercel AI SDK?

Yes. The captureorder tool handles the final transaction. Ensure your environment variables for keys are handled securely on the server side.

Q: How do I manage carts using Commerce.js and Vercel AI SDK?

Use createcart to start a session and updatecartitem to modify contents. The agent keeps the cart state synced based on user input.

Connect Commerce.js to your Vercel AI SDK projects to stream product data and cart updates directly into your UI components.

Real-time product catalog rendering

Pipe live inventory data from your store straight into your React or Next.js components. Use `list_products` to pull current catalog state without building a custom backend layer. Your AI agent processes this data and streams it to the user. The client-side interface updates instantly as results arrive.

Streamlined checkout via AI SDK

Automate the entire path from cart creation to order capture. The agent manages `create_cart` and `add_to_cart` logic while you handle the UI state. Once the user confirms, the agent executes `generate_checkout_token` and `capture_order`. Everything happens within the lifecycle of your stream.

Order monitoring with Commerce.js

Keep track of store performance by querying specific order data. Your agent uses `list_orders` to fetch recent activity for your dashboard. Verify individual transactions using `get_order`. It's a quick way to show status updates to your users without leaving the development environment.

Setup guide

Set up Commerce.js 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 Commerce.js 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 Commerce.js transactions",
});

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