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