I get this error "request is not authorized" when using Docker image: ghcr.io/chand1012/alpaca-mcp-server

I tried for a few hours but couldn't use MCP with Claude, I kept getting the error:

```bash
Error: Error executing tool get_account_info: {"code":40110000,"message":"request is not authorized"}
```

Finally cloned the repo and tried to build a docker image myself and it worked. Not sure why you're using a separate repo for for the docker image.

Also, would be good to add this to your readme for Claude code:

```bash
# Add MCP via docker to Claude Code
claude mcp add alpaca-mcp --env ALPACA_API_KEY=${ALPACA_API_KEY} --env ALPACA_SECRET_KEY=${ALPACA_SECRET_KEY} -- docker run -i -e ALPACA_API_KEY -e ALPACA_SECRET_KEY DOCKERIMAGEHERE
```
