Questions

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

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