MU* is a shorthand to refer collectively to a family of text-based[1] multi-user virtual world servers comprising:

The asterisk is often used in computer programming languages to represent a wildcard (any number of arbitrary characters), which suggests a usage that encompasses MUDs in general. However, confusingly, MU* is often used in a manner exclusive of services specifically described as MUDs, with the MU* term meant to distance the TinyMUD family of "social MUDs" from "combat-oriented" MUDs.[2] With the dominant usage of MUD being as a generic term[1] rather than specifically denoting combat-oriented games — indeed, both TinyMUD and MOO are MUDs in name (MOO stands for MUD, Object-Oriented), while MUSH and MUCK are backronymed puns on "MUD" — this positions MU* as actually being a subset of MUD.[3]

"TinyMUD was deliberately intended to be distanced from the prevailing hack-and-slay AberMUD style, and the "D" in its name was said to stand for "Dimension" (or, occasionally, "Domain") rather than "Dungeon;" this is the ultimate cause of the MUD/MU* distinction that was to arise some years later."

All of these things are muds [...] For instance, you may read that MUSH stands for "Multi-User Shared Hallucination". My advice is to forget the acronyms. Consider all of these strange things to be types of muds and leave it at that."
