Questions

Can ChatGPT run zsh-history-substring-search on my computer?
Yes. With BCD on your Mac or Linux computer and command permission turned on for it, ChatGPT runs zsh-history-substring-search there and reads the output. Claude and other apps with MCP connectors can too.

Do I need to install zsh-history-substring-search first?
No. If Homebrew is installed, the AI can run brew install zsh-history-substring-search 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.
