Real-time billing visibility in Vercel AI SDK

Feed live subscription and order data into your React or Next.js components as it happens. By connecting this MCP Server, your agent pulls raw figures from `list_subscriptions` and `list_orders` to update your UI instantly. Your users won't sit through stale dashboards. Since this setup works with edge functions, data flows directly from the merchant to the browser, keeping your customer-facing tools fast and responsive.

Dynamic product catalog management

Show the right pricing options by calling `list_products` and `list_variants` on the fly. Your agent can adjust its output based on what is actually available in your store. This prevents the common mismatch between static UI code and your live inventory. When you update a price, your AI client reflects that change immediately without requiring a redeploy.

Automated account auditing

Trigger a full check of your store health using `get_account_info` and `list_webhooks`. You can build a status page that alerts you to misconfigured endpoints or missing account data. Your agent parses the JSON response to flag issues before they impact revenue. It turns a manual auditing task into a background process that runs whenever you need it.

Setup guide

Set up Lemon Squeezy 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 Lemon Squeezy 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 Lemon Squeezy transactions",
});

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

Common questions about Lemon Squeezy MCP in Vercel AI SDK

Install the necessary packages and initialize the client using your endpoint URL. Use the `createMCPClient` function to bridge the connection, then pass the exposed tools directly into your `generateText` calls.

Yes. The server is built to handle lightweight requests that fit within edge runtime constraints. This ensures your billing logic stays performant while serving your users.

It handles it easily by streaming only the specific data points your agent needs. Avoid fetching the entire database by selecting specific tools like `get_order` for individual lookups.

Vinkius hosts the server in an ephemeral sandbox, meaning your data isn't stored permanently. The server acts as a transient pipe between the API and your agent, keeping your sensitive merchant records isolated.

Your key is handled through a single endpoint token provided by Vinkius. We keep your credentials out of your frontend code, ensuring they remain encrypted and inaccessible to unauthorized parties.
