Yes it's possible, there are quite a few bots out there. The 2 most popular ones are I4tez bot and MMOViper. They're both good, but I4tez is more complete. The problem is it's programmed for a destroyer bot, you need to find a script file for KFM (or create your own) to level up a KFM from 1-45.
I'm sure you can find one though. GL!
