How to Use the Leal MCP in Vercel AI SDK

Q: Can Leal update member segments in my Vercel AI SDK app?

Yes, you can use getsegment and listsegments to pull data. Your agent then uses this information to personalize the experience for your users.

Perplexity

Live member data streaming

Your AI client pushes customer points and profile updates straight to your frontend without waiting for spinners. Use `get_member_balance` to show real-time rewards status as your user types. This creates a snappy feel for your dashboard. Your users see their loyalty status update the moment the agent processes their request.

Instant campaign insights

Trigger `list_campaigns` to surface current promotions directly inside your application interface. Your agent fetches the latest marketing data so your UI stays current. Stop hardcoding your promo banners. Let your agent pull valid offers from the database and render them dynamically as the state changes.

Verified loyalty connections

Run `check_leal_status` during your app initialization to confirm the connection is active. You catch service interruptions before they hit your users. This provides a clean way to handle downtime. You keep your UI reactive even when the underlying loyalty service hits a snag.

Setup guide

Set up Leal 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 Leal 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 Leal transactions",
});

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