FAQ from Alpaca Trading MCP Server

What trading operations does the server support?

It supports placing market and limit orders, canceling orders, and retrieving portfolio summaries. Order execution depends on the Alpaca account (paper or live).

How do I obtain Alpaca API credentials?

Alpaca API keys can be acquired from the Alpaca developer web console. Refer to the Alpaca documentation for getting started.

Is this server safe for live trading?

The server defaults to paper trading (ALPACA_PAPER=TRUE) and includes error handling and logging. The README includes a disclaimer that trading involves risk and the author is not responsible for financial losses.

What are the prerequisites to run the server?

You need uv (Python package manager) and optionally Claude for Desktop for testing. Python and the dependencies listed in uv.lock are installed automatically.

Does real-time market data require a specific account?

Real-time quotes and historical bars may only be fully accessible with a Live trading account, depending on the Alpaca subscription level. Paper trading accounts might have limited market data.
