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