Twelve Data MCP Server

# Twelve Data MCP Server

## Overview

The Twelve Data MCP Server provides a seamless integration with the Twelve Data API to access financial market data. It enables retrieval of historical time series, real-time quotes, and instrument metadata for stocks, forex pairs, and cryptocurrencies.

> Note: This server is currently in early-stage development; features and tools may evolve alongside updates to the Twelve Data API.

## Obtaining Your API Key

To use Twelve Data MCP Server, you must first obtain an API key from Twelve Data:

1. Visit [Twelve Data Sign Up](https://twelvedata.com/register?utm_source=github&utm_medium=repository&utm_campaign=mcp_repo).
2. Create an account or log in if you already have one.
3. Navigate to your Dashboard and copy your API key.

Important: Access to specific endpoints or markets may vary depending on your Twelve Data subscription plan.

## U-tool
u-tool is an AI-powered universal router for the Twelve Data API that transforms how you access financial data. Instead of navigating 100+ individual endpoints and complex documentation, simply describe what you need in plain English.

How it works:
🧠 Natural Language Processing: Understands your request in conversational English
🔍 Smart Routing: Uses vector search to find the most relevant endpoints from Twelve Data's entire API catalog
🎯 Intelligent Selection: Leverages OpenAI GPT-4o to choose the optimal method and generate correct parameters
⚡ Automatic Execution: Calls the appropriate endpoint and returns formatted results

What you can ask:
📈 "Show me Apple stock performance this week"
📊 "Calculate RSI for Bitcoin with 14-day period" 
💰 "Get Tesla's financial ratios and balance sheet"
🌍 "Compare EUR/USD exchange rates over 6 months"
🏦 "Find top-performing tech ETFs"

Supported data categories:
- Market data & quotes • Technical indicators (100+)
- Fundamental data & financials • Currencies & crypto
- Mutual funds & ETFs • Economic calendars & events

One tool, entire Twelve Data ecosystem. No API documentation required.
