Perplexity

Real-time market data in your UI

Feed live stock and crypto prices directly into your React or Next.js components using `get_stock_quote` and `get_crypto_quote`. Your users watch the numbers update without waiting for a stale page refresh. This MCP Server pushes raw JSON responses straight through the stream. You handle the formatting, keeping your UI responsive while the AI processes incoming market fluctuations.

Financial analysis on the edge

Pull deep company data with `get_stock_financials` and `get_stock_stats` during your edge function execution. You get the hard numbers needed for valuation models without heavy backend overhead. Everything stays within your request pipeline. The data arrives, the model interprets the balance sheet, and your user sees the result instantly.

Track market sentiment automatically

Query `get_stock_news` to fetch headlines for any ticker and pipe them into your summary agent. You get the latest context on stock performance immediately after a price change. Stop building manual scrapers. This tool handles the connection so you can focus on how your AI client interprets the news for your users.

Setup guide

Set up IEX Cloud 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 IEX Cloud 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 IEX Cloud transactions",
});

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

Common questions about IEX Cloud MCP in Vercel AI SDK

Install the MCP client package via npm and initialize it with your Vinkius endpoint URL. Pass the tools directly into your `generateText` or `streamText` function calls to make them available to your agent.

Yes, but watch your API credit usage. Since the data streams live, frequent polling will burn through your budget quickly if you aren't careful with your update intervals.

Absolutely. Because the data returns as structured JSON, you can map the fields directly to your chart or table components to display live market movements.

Latency is minimal because the transport layer handles the connection efficiently. Most delays come from the model's processing time, not the data retrieval itself.

Vinkius handles your authentication securely at the server level. You don't need to expose your credentials in your frontend code, as the endpoint token mediates the connection.
