Twelve Data MCP Server
Connect Claude, ChatGPT, and other AI assistants to the Twelve Data financial API — real-time and historical prices, 60+ technical indicators, fundamentals, earnings, dividends, ETFs, company news, market movers, and more.
You need a Twelve Data account. Sign up at twelvedata.com.
There are two ways to use it. Most people should use the cloud server (Option 1) — there is nothing to install.
Option 1 — Use our cloud server (recommended)
Connect your AI assistant to our hosted server:
https://mcp.twelvedata.com/mcpThat's it. No installation, no API key to copy and paste. When you connect, a browser window opens and you log in with your Twelve Data account — your personal API key is linked automatically and stays tied to your account.
How to add it
Claude (Desktop / Web) and ChatGPT support custom connectors / MCP servers:
- Open your assistant's Connectors (or Integrations / MCP servers) settings.
- Add a new connector with the URL
https://mcp.twelvedata.com/mcp. - When prompted, click Connect / Log in — a Twelve Data login page opens in your browser.
- Authorize, and you're done. Ask things like "What's the RSI for AAPL?" or "Show me TSLA's latest earnings."
