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.
