Questions
Can ChatGPT run cowsay on my computer?
Yes. With BCD on your Mac or Linux computer and command permission turned on for it, ChatGPT runs cowsay there and reads the output. Claude and other apps with MCP connectors can too.
Do I need to install cowsay first?
No. If Homebrew is installed, the AI can run brew install cowsay 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.
Try it on your computer
BCD connects ChatGPT, Claude and other AI apps to your own Mac, Windows or Linux computer. One computer is free, with 20,000 tool calls a month and no card.
