Composer MCP Server

Product Introduction

1. The Composer MCP Server is an API-driven platform that enables AI systems like Claude to create, backtest, and execute automated trading strategies (called "symphonies") across stocks, ETFs, and cryptocurrencies. It acts as an intermediary between large language models and financial markets through standardized Model Context Protocol (MCP) integrations.
2. Its core value lies in providing AI agents with institutional-grade trading infrastructure, including real-time market data integration, strategy optimization tools, and automated order execution capabilities while maintaining security compliance for financial operations.

Main Features

1. Strategy automation engine supports multi-asset portfolio construction using technical indicators like RSI, EMA, and MACD with configurable risk parameters such as maximum drawdown limits and volatility targets.
2. Backtesting API delivers millisecond-level historical performance simulations with adjustable timeframes (1 minute to 10 years) and benchmark comparison tools against indices like S&P 500.
3. Symphony marketplace integration provides access to 1,000+ pre-optimized strategies with detailed metadata including Sharpe ratios, alpha generation metrics, and sector exposure analyses.

Problems Solved

1. Eliminates manual coding requirements for algorithmic trading by translating natural language instructions into executable investment strategies through MCP-standardized API endpoints.
2. Serves quantitative researchers and retail investors seeking to operationalize AI-generated trading ideas without infrastructure development costs or regulatory compliance overhead.
3. Enables scenario testing for strategy validation through parallel live trading of multiple symphonies with automatic performance tracking and risk-adjusted return comparisons.

Unique Advantages

1. Native integration with Claude's tool use capabilities outperforms generic API wrappers through MCP-specific optimizations for financial data structures and low-latency order routing.
2. Patent-pending "symphony orchestration" technology allows simultaneous management of 50+ live strategies with conflict detection and liquidity optimization across brokerage accounts.
3. Institutional-grade security architecture implements FIX protocol encryption for order transmission and SOC 2-compliant audit trails for all AI-initiated trading actions.

Frequently Asked Questions (FAQ)

1. What authentication is required for live trading? Live trading functionality requires both an API key (generated through Composer's dashboard) and active subscription, though strategy backtesting remains available without authentication. API keys implement HMAC-SHA256 encryption with 15-minute JWT token rotation.
2. Which LLM clients are officially supported? Primary support exists for Claude Desktop (Pro/Max plans) and Cursor IDE through pre-configured MCP extensions, while generic MCP implementations can connect via documented configuration templates requiring manual header injection.
3. What asset classes are available for trading? The platform currently supports 8,000+ equities (NYSE/NASDAQ), 300 ETFs, and 50 cryptocurrencies across 4 major exchanges with asset coverage expanding through quarterly updates. Futures and options trading remain in beta testing.
