Track real-time price movements

Need to show the user a stock's current value? Use `get_real_time_price` for quick updates, or run `get_quote` for full ticker details. This data streams right into your React component; no loading spinner needed. For historical context, fetch candle data using `get_time_series`. It supports intervals from 1min all the way up to 1 month.

Calculate technical momentum indicators

Determine if a stock is overbought or oversold by checking signals. Run `get_rsi` (relative strength index) or `get_stochastic`. These calculations give immediate feedback on market pressure. Want to track trends? Use `get_macd` for momentum analysis, or calculate simple averages with `get_sma` and exponential moving averages via `get_ema`.

Search and compare financial assets

Start by finding the right instrument. Use `search_symbols` to filter by exchange or type, then get a list of available stocks with `get_stock_list`. You can also check crypto pairs using `get_crypto_list`. Need rates? Fetch currency data directly. Grab an exchange rate with `get_exchange_rate`, or compare foreign pairs using `get_forex_list`.

Setup guide

Set up Twelve Data 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 Twelve Data 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 Twelve Data transactions",
});

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