概要

What is Composer MCP Server?

Composer MCP Server is the official Model Context Protocol server from Composer that lets MCP-enabled LLMs (Claude Desktop, Cursor, OpenAI Agents, etc.) validate investment ideas through backtests and trade multiple automated strategies—called “symphonies”—in parallel to compare live performance.

How to use Composer MCP Server?

Install uv (Python package manager), then either download and drag the composer-trade-mcp.dxt file into Claude Desktop’s Extensions settings, or add a manual configuration in claude_desktop_config.json using uvx composer-trade-mcp. Backtesting works without a Composer account; full account features require an API key.

Key features of Composer MCP Server

  • Create automated investing strategies using RSI, MA, EMA, and other indicators.
  • Backtest ideas quickly with a fast feedback loop for AI iteration.
  • Monitor aggregate portfolio statistics and individual symphony performance.
  • Control investments – adjust exposure, save, or liquidate symphonies via AI.
  • Trade equities and crypto with symphony-based rebalancing.
  • Compare strategy performance against benchmarks like the S&P 500.

Use cases of Composer MCP Server

  • Build and backtest a 60-40 equity-bond strategy with a single prompt.
  • Evaluate a crypto strategy with maximum drawdown constraints.
  • Ask AI to compare your strategy’s performance against the S&P 500 and plot results.
  • Identify your best-performing symphonies and analyze why they work.
  • Research market trends and have AI recommend adjustments to your portfolio.

よくある質問

1

What do I need to run Composer MCP Server?

You need Python and the package manager `uv`. Installation via DXT or manual config is quick; no account is needed for basic backtesting.

2

Do I need an API key and a subscription?

An API key is required to interact with your Composer account (view holdings, save symphonies). Trading symphonies requires a paid subscription, but you can liquidate positions without one. A 14-day free trial is available.

3

What tools does Composer MCP Server provide?

It offers 26 tools including `create_symphony`, `backtest_symphony`, `save_symphony`, `get_account_holdings`, `get_portfolio_daily_performance`, `invest_in_symphony`, `withdraw_from_symphony`, `liquidate_symphony`, `execute_single_trade`, and more.

4

Which tools should I handle with care?

Tools that affect your funds: `invest_in_symphony`, `withdraw_from_symphony`, `skip_automated_rebalance_for_symphony`, `go_to_cash_for_symphony`, `liquidate_symphony`, `rebalance_symphony_now`, and `execute_single_trade`. Do not set these to “Always Allow”.

5

Where can I find logs if something goes wrong?

Logs are located at `%APPDATA%\Claude\logs\mcp-server-composer.log` on Windows and `~/Library/Logs/Claude/mcp-server-composer.log` on macOS.
