You tried to read the server description, but an annoying goose stole it...oh well.
All jokes aside, the Mojang server is more of a PvP server (mainly with kits), but also has survival aspects and utilizes "item generators" (nothing too fancy, just command blocks spitting items out) as a way of collecting resources both as currency / value but also to spend them on valuable items. However, it's mostly just a server I use for testing, so don't expect anything too overly exciting, high-quality, or custom coded. I might open up the server later on if I decide to, but for now, it'll be whitelisted.
The Mojang server will stay a cloudy mystery (for now)!
