Interact with Twelve Data APIs to access real-time and historical financial market data for your AI agents.
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.
To use Twelve Data MCP Server, you must first obtain an API key from Twelve Data:
Important: Access to specific endpoints or markets may vary depending on your Twelve Data subscription plan.
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: š§ Natural Language Processing: Understands your request in conversational English š Smart Routing: Uses vector search to find the most relevant endpoints from Twelve Data's entire API catalog šÆ Intelligent Selection: Leverages OpenAI GPT-4o to choose the optimal method and generate correct parameters ā” Automatic Execution: Calls the appropriate endpoint and returns formatted results
What you can ask: š "Show me Apple stock performance this week" š "Calculate RSI for Bitcoin with 14-day period" š° "Get Tesla's financial ratios and balance sheet" š "Compare EUR/USD exchange rates over 6 months" š¦ "Find top-performing tech ETFs"
