Questions
Can ChatGPT run pinentry-mac on my computer?
Yes. With BCD on your Mac or Linux computer and command permission turned on for it, ChatGPT runs pinentry-mac there and reads the output. Claude and other apps with MCP connectors can too.
Do I need to install pinentry-mac first?
No. If Homebrew is installed, the AI can run brew install pinentry-mac 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.
