Doesn't need a terminal: run it in RPC mode to send/receive JSON over stdio. That's how the pi-coding-agent Emacs package works, which is the only way I've ever used Pi.

It seems pretty well done: when I added permission requests to the `bash` tool, the "Are you sure y/N" requests started appearing just like they were native to Emacs.

Some of us never left the terminal. Welcome to the future.
