I'm not asking how to do this, because I already know how to design/use noise functions and stuff, but I am wondering if it is possible to use Addons or ModPE in order to design an algorithm that generates custom Minecraft worlds. I know it's possible to do this using PocketMine plugins, but I'm not sure about the implementations for MCPE client mod creation. If it is possible, I would like the names of the functions/json library data I would need to use in order to build my terrain generator. Keep in mind that I'm not a total noob and I have done stuff like this before on PC Forge and Spigot, so if you need to go into any mathematical/coding jargon, you don't need to dumb it down. I think that's about all.
