Install

brew install cosign

“Install cosign with Homebrew and show me its version”
“Read cosign --help and give me three useful examples for my files”
“Update cosign and tell me what changed”

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

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