Perplexity

Stream live market quotes into your UI

Feed real-time pricing directly into your React or Next.js components. Use `get_latest_quote` to fetch bid and ask data without the typical latency of manual polling. Your users see price changes as they happen. The data flows through your stream, keeping the UI synced with current market conditions.

Execute orders directly from your frontend

Route trade requests straight from the user interface using `place_new_order`. You handle the logic of the trade, while the MCP server manages the request lifecycle. Trigger the transaction and follow up with `activate_pending_order` to finalize the trade. It keeps the heavy lifting on the server while the SDK manages the state.

Manage portfolio state in real-time

Display current holdings by calling `list_active_positions` within your application flow. This gives your users a live view of their portfolio performance. Check account details via `get_brokerage_account` to ensure sufficient margin before any trade. It removes the guesswork from order placement.

Setup guide

Set up lemon.markets 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.markets 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.markets transactions",
});

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