Overview

What is Alpaca MCP Server?

Alpaca MCP Server is a Model Context Protocol server for Alpaca, enabling LLMs like Claude to interact with the Alpaca trading API through natural language. It allows trading stocks, checking positions, fetching market data, and managing account details.

How to use Alpaca MCP Server?

Requires Python 3.10+, Alpaca API keys, and an MCP client such as Claude for Desktop. Clone the repository, install dependencies (mcp, alpaca-py, python-dotenv), create a .env file with credentials, and run python alpaca_mcp_server.py. Configure Claude for Desktop by adding the server to claude_desktop_config.json with the appropriate command, arguments, and environment variables.
