About alpaca-mcp-server
alpacahq/alpaca-mcp-server
Alpaca’s official MCP Server lets you trade stocks, ETFs, crypto, and options, run data analysis, and build strategies in plain English directly from your favorite LLM tools and IDEs
Built with FastMCP and OpenAPI, it dynamically generates trading tools from Alpaca's API specifications rather than hand-crafting them, enabling automatic schema alignment and toolset filtering via `ALPACA_TOOLSETS`. Integrates with Claude, Cursor, VS Code, and PyCharm through the Model Context Protocol (MCP) stdio transport, allowing LLMs to execute trading operations with real-time market data access and portfolio management directly within IDE environments.
About composer-trade-mcp
invest-composer/composer-trade-mcp
Composer's MCP server lets MCP-enabled LLMs like Claude backtest trading ideas and automatically invest in them for you
Integrates with the Composer backtesting and portfolio management platform via HTTP transport, supporting Claude Desktop, Cursor, n8n, and other MCP-enabled clients. Provides LLMs access to tools for strategy creation using technical indicators (RSI, MA, EMA), rapid backtesting feedback loops, searching a 1000+ strategy database, and live portfolio monitoring—enabling AI to iteratively refine investment ideas and execute trades across equities and crypto. Requires authentication via Composer credentials or API keys, with optional subscription for live trading execution.
