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

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.
