Questions

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

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