Composer MCP Server

Provides an MCP server to create, backtest, and monitor Composer investment symphonies via HTTP.

Installation

Add the following to your MCP client configuration file.

Configuration

{
  "mcpServers": {
    "invest-composer-composer-trade-mcp": {
      "url": "https://ai.composer.trade/mcp"
    }
  }
}

You can use this MCP server to validate investment ideas, backtest strategies, and manage multiple symphonies with compatible LLMs. It provides a programmable interface to create, backtest, and monitor automated investment strategies across a variety of assets, helping you compare performance and adjust exposure over time.

How to use

Connect your MCP-enabled LLM to the Composer MCP Server using the remote MCP URL https://ai.composer.trade/mcp. Once connected, you can create automated strategies (symphonies), backtest them against historical data, and compare live performance across multiple strategies. Use the available tools to search, backtest, save, and manage symphonies, as well as to monitor portfolio and symphony performance.

How to install

Prerequisites: ensure you have a compatible environment for your MCP client. The following steps assume you are setting up a client that can reach the Composer MCP Server over HTTP.

# No local MCP server is required; you connect to the remote Composer MCP URL.
# Use your MCP client (Claude Desktop, Claude Code, Cursor, n8n, or another) to point at the MCP server.

Additional sections

Configuration, security, and troubleshooting notes help you get the most out of your MCP integration.
