Questions
Can ChatGPT run fail2ban on my computer?
Yes. With BCD on your Mac or Linux computer and command permission turned on for it, ChatGPT runs fail2ban there and reads the output. Claude and other apps with MCP connectors can too.
Do I need to install fail2ban first?
No. If Homebrew is installed, the AI can run brew install fail2ban for you.
Is it safe?
A new computer starts read-only: running commands is turned on per computer, and BCD reaches only the folders you allow.
