About

The Composer MCP server allows MCP-enabled LLMs, such as Claude, to backtest trading ideas and automatically invest in them. It provides a comprehensive set of tools for defining and managing automated trading strategies ('symphonies'), interacting with brokerage accounts, viewing portfolio statistics, and executing trades. Users need an API key from Composer, which can be obtained after creating an account. The documentation also highlights important considerations for tool usage, especially for actions that modify accounts or funds, and recommends using Claude Opus 4 for better tool interaction.
