Twelve Data MCP Server

The Twelve Data MCP Server turns a complex financial data API into an intuitive, conversational interface for AI assistants. By exposing Twelve Data’s extensive catalog of market data—historical time series, real‑time quotes, and instrument metadata—for stocks, forex pairs, and cryptocurrencies, the server lets developers retrieve precise financial information without grappling with endpoint URLs or parameter quirks. Instead of hunting through 100+ endpoints, a user can simply ask the AI in plain English and receive structured results instantly.

At its core, the server is built around u‑tool, an AI‑powered universal router that translates natural language requests into the correct Twelve Data API calls. The routing pipeline combines vector search over the full API catalog, GPT‑4o for intent recognition and parameter generation, and automated execution of the chosen endpoint. This means that even complex queries—such as calculating a 14‑day RSI for Bitcoin or pulling Tesla’s balance sheet—are handled transparently, returning neatly formatted JSON that the AI can consume or present directly to end users.

Key capabilities include:

• Broad data coverage: market quotes, technical indicators (100+), fundamental financials, currency and crypto prices, mutual funds & ETFs, and economic calendars.
• Smart selection: the server chooses the most appropriate endpoint automatically, reducing API call errors and simplifying development.
• Configurable scope: developers can limit the server to a subset of popular endpoints for lightweight use or enable full routing for exploratory queries.
• Dual integration paths: local stdio servers via UV or pip, and a remote MCP endpoint for distributed setups.

Real‑world scenarios where this server shines are plentiful: automated trading bots that need on‑demand market data, financial chatbots that answer user questions about stock performance, portfolio analytics tools that pull the latest fundamentals, or educational platforms that demonstrate technical analysis in real time. By embedding the MCP server into an AI workflow, developers can focus on business logic rather than API plumbing, accelerating time to market and reducing maintenance overhead.

Unique advantages of the Twelve Data MCP Server include its natural‑language routing, which eliminates the need for developers to read extensive documentation, and its tight integration with Claude Desktop and VS Code, allowing instant data retrieval within popular development environments. The result is a powerful, developer‑friendly bridge between AI assistants and the rich financial data ecosystem provided by Twelve Data.
