I also did this a few months ago using a custom MCP server I built for the Alpaca API, the yfinance MCP server, and a reddit MCP server, and the "sequential thinking" mcp server. I hade claude write a prompt that combined them all together starting with checking r/pennystocks for any news, looking up the individual ticker symbols with alpaca and yfinance, checking account balance and making a trade only if a very particular set of criteria was met. I used claude code instead of desktop so that I could run it as a cron job, and it all works! I mostly built it to see if I could, not for any financial gain. I had it paper trading for a few months and it made a 2% profit on 100k. I really think someone that knows more about trading could do quite well with a setup like this, but it's not for me.
