Perplexity

Live profile and streak tracking

Feed live user stats into your UI components without waiting for background jobs. The SDK handles the stream, so your users see their streak and total XP updates the moment the AI executes `get_user_by_username` or `get_user_by_id`. This keeps your application interface responsive. By avoiding standard loading spinners, you provide a faster experience for learners checking their daily progress.

Real-time leaderboard updates

Hook your dashboard into live competitive data using `get_daily_leaderboard` and `get_leaderboard`. The Vercel AI SDK pushes these results straight to your frontend state. Your users get immediate feedback on their rank changes. It turns static stats into a dynamic feed that updates as fast as the AI client can process the MCP Server response.

Instant vocabulary hint delivery

Surface translation pairs inside your chat interface using `get_dictionary_hints`. The AI fetches the tokens and the SDK streams the text directly to the user's screen. This creates a faster way to build study tools. You avoid the lag of traditional API round-trips by letting the MCP Server push data directly into your generative UI.

Setup guide

Set up Duolingo 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 Duolingo 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 Duolingo transactions",
});

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

Common questions about Duolingo MCP in Vercel AI SDK

Connect the MCP Server to your project using the MCP client library. Call the tools within your streamText function to pipe the data directly to your React or Svelte components.

Yes. The tools return raw data that the SDK handles as standard text streams. This allows you to render profile updates or leaderboard ranks as they arrive.

It is built to be lightweight and compatible. You can execute these tools from your edge routes to keep your site's response time low.

We only handle the specific data points requested by your agent. The server uses your provided JWT token to authenticate, and the Vercel AI SDK processes this in an ephemeral memory space that clears after every request.

The MCP Server acts as a buffer. If the underlying API changes, we update the tool logic, and your frontend code remains untouched.
