Frequently asked questions

1

What are the runtime requirements?

Python 3.10 or higher, along with the packages `mcp`, `alpaca-py`, and `python-dotenv`. You also need a valid Alpaca API key and secret key.

2

How does the server authenticate with Alpaca?

It uses API key authentication. You provide your Alpaca API key ID and secret key (via `.env` file or environment variables in the config). By default, the server uses Alpaca's paper trading environment.

3

Can I use real money trading instead of paper trading?

Yes. You can change from paper trading to real money trading by modifying the `TradingClient` initialization parameter `paper=True` to `paper=False` in the server code.

4

Where does my trading data reside?

All account and order data is stored on Alpaca's servers. The server only retrieves or sends data through their API; it does not store any data locally.

5

What security should I be aware of?

This server will have access to your Alpaca account and can place real trades. Always review what Claude is suggesting before approving any trades.
