How to Use the Commerce Layer MCP in Vercel AI SDK

Q: How does Vercel AI SDK handle Commerce Layer draft orders?

The agent uses createorder to generate drafts based on customer requests. Your Next.js app receives the structured response and renders a checkout link directly in the chat interface.

Q: How do I close the MCP connection in my Next.js API route?

Always call mcpClient.close() at the end of your Vercel serverless execution. This prevents hanging TCP connections and ensures your API routes scale efficiently.

Feed live Commerce Layer order data directly into your React components in real-time with the Vercel AI SDK.

Real-time checkout generation in Vercel AI SDK

The `create_order` tool lets your React frontend build draft checkouts on the fly without waiting for slow backend page refreshes. When a user asks your agent to buy an item, the SDK calls this endpoint and shows the pending order card immediately. You don't need loading spinners because the data streams straight into your UI components. The agent pulls active payment options via `list_payment_methods` and shows them in the chat window the millisecond they load.

Live inventory and price lookups via MCP Server

The `list_prices` tool fetches current SKU prices directly from your Commerce Layer catalog to update your edge-rendered storefront. Your Vercel AI SDK agent uses this tool to answer pricing questions during live chat sessions. By combining this with `list_skus`, your frontend displays product availability instantly. The agent matches user queries to active stock levels without hitting a separate middleware database.

Instant order tracking inside your chat UI

The `get_order` tool retrieves shipping updates and order status directly from Commerce Layer to show customers where their packages are. Your Vercel AI SDK agent reads the status and renders a progress bar component right in the conversation. Instead of redirecting users to a tracking portal, the agent checks `list_shipments` to show actual delivery details. This keeps your customers on your site and reduces support tickets.

Setup guide

Set up Commerce Layer 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 Layer 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 Layer transactions",
});

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

Common questions about Commerce Layer MCP in Vercel AI SDK

You configure your Vinkius endpoint token inside the Vercel AI SDK setup block. Pass this token using the MCP client transport configuration to grant your agent secure access to your store tools.

Yes, this setup is fully compatible with Vercel Edge Functions. The lightweight client protocol runs without Node.js dependencies, letting you fetch catalog details from anywhere.

The agent uses `create_order` to generate drafts based on customer requests. Your Next.js app receives the structured response and renders a checkout link directly in the chat interface.

Always call `mcpClient.close()` at the end of your Vercel serverless execution. This prevents hanging TCP connections and ensures your API routes scale efficiently.

Yes, because Vinkius runs the MCP server in an isolated sandbox that never stores your customer addresses or order history. Your API keys and customer records transit through secure, ephemeral memory that wipes immediately after the agent runs the tool.
