Questions

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

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