Questions

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

Do I need to install epubcheck first?
No. If Homebrew is installed, the AI can run brew install epubcheck 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.
