Questions

Can ChatGPT run eigen@3 on my computer?
Yes. With BCD on your Mac or Linux computer and command permission turned on for it, ChatGPT runs eigen@3 there and reads the output. Claude and other apps with MCP connectors can too.

Do I need to install eigen@3 first?
No. If Homebrew is installed, the AI can run brew install eigen@3 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.
