Well, I use, for example, a custom function to set the health, AC_Sethealth. If you want to test your anti cheat, create a command that uses the normal SetPlayerHealth function. Like that, you can test if it works. I've been working on a GM for over a year now, and I never needed any 3rd party GTA SA tools, so that should be the same for you.
There are numerous scriptwise solutions to imitate the cheat program functions, without using a forbidden program.
