I'm also not aware of any pre-fabed function in AUCTeX for this. But
you can easily build your own like this:
--8<---------------cut here---------------start------------->8---
(defun ConTeXt-arg-mandatory-in-brackets (optional &rest args)
"Parse its arguments but use square brackets when they are inserted."
(let ((TeX-arg-opening-brace LaTeX-optop)
(TeX-arg-closing-brace LaTeX-optcl))
(if (equal (length args) 1)
(TeX-parse-argument optional (car args))
(TeX-parse-argument optional args))))
--8<---------------cut here---------------end--------------->8---
This is based on `TeX-arg-free' which is defined as:
--8<---------------cut here---------------start------------->8---
(defun TeX-arg-free (optional &rest args)
"Parse its arguments but use no braces when they are inserted."
(let ((TeX-arg-opening-brace "")
(TeX-arg-closing-brace ""))
(if (equal (length args) 1)
(TeX-parse-argument optional (car args))
(TeX-parse-argument optional args))))
--8<---------------cut here---------------end--------------->8---
