Stream checkouts to your UI

Trigger `create_checkout` and push the resulting URL straight to your React or Next.js components. The AI generates the session, and your app renders it before the user finishes their thought. Stop waiting for backend round-trips. By hooking this MCP server into the SDK's streaming pipeline, your UI reacts to billing state changes in real-time.

Manage subscriptions on the fly

Use `get_subscription` and `update_subscription` to let your AI agent handle account changes. The agent reads the user's current plan and applies adjustments without a single custom API route. Your application logic stays clean. The AI client handles the heavy lifting of parsing subscription objects while you focus on the user experience.

Verify access in real-time

Run `validate_license` inside your edge functions to check user status during page loads. It keeps your app secure without adding latency to your auth flow. This MCP server ensures the AI knows exactly what a user can access. Your Vercel AI SDK implementation stays lightweight and fast.

const transport = new StreamableHTTPClientTransport(
  new URL("https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp")
);

const mcpClient = await createMCPClient({ transport });

Common questions about Lemon Squeezy (Merchant of Record & Payments) MCP in Vercel AI SDK

Yes. You connect the server to your agent and invoke tools like `create_checkout` or `cancel_subscription` directly from your code. It handles the entire transaction lifecycle.

It acts as a set of callable functions. You pass the tools into your agent, and the SDK manages the execution and streaming of the results back to your frontend.

Absolutely. Since the MCP server communicates over HTTP, your edge functions can trigger actions like `create_customer` without hitting cold start issues.

Yes. The server only touches your specific store data, such as customer emails and order IDs. All communication is encrypted, and no sensitive payment credentials ever hit your local machine.
