Composer MCP Server

The Composer MCP Server gives Claude AI the power to backtest investment ideas and execute automated trading strategies. Trade across stocks, ETFs, and crypto directly in Claude.

The Composer MCP Server integrates with AI assistants like Claude to enable seamless investment strategy creation, backtesting, and execution. Users can design automated trading strategies (called 'symphonies') for stocks, ETFs, and crypto, leveraging indicators like RSI and moving averages. The platform offers a vast library of pre-built strategies and robust backtesting tools to validate ideas before live trading. Advanced features include real-time performance monitoring, portfolio rebalancing, and trade execution, though these require an API key and Composer subscription. The free tier allows backtesting without an account. Designed for AI collaboration, it simplifies complex trading tasks through natural language prompts, making it ideal for both novice and experienced investors. Setup involves installing an extension in Claude or Cursor, with optional API integration for full functionality. A 14-day free trial is available for live trading.
