Introduction
Unofficial, source-verified documentation for the mcMMO Minecraft plugin - for both players and server owners. Actively maintained by Hyronic Studios.
What is this?
This is an UNOFFICIAL documentation project. Every mechanic, value, and formula here is checked directly against the mcMMO source code and also references the official documentation, so it aims to be more accurate and far more detailed.
mcMMO is not our project and has no affiliation with Hyronic Studios. We do not own, maintain, or develop it, and we are not responsible for the plugin, its support, or its bug fixes. These are unofficial docs we maintain purely to make mcMMO easier to search and use for our own community.
These docs target mcMMO 2.2.054 on Minecraft 1.20.5+ (Spigot / Paper / Folia). Numbers shown are mcMMO's defaults - your server owner may have changed them.
What does this documentation offer?
This site is meant to save you time and guesswork.
-
You can check the real default values from mcMMO 2.2.054 instead of relying on old wiki pages or random forum answers.
-
You can look up what a skill, command, permission, or config option actually does before changing your server.
-
You can see where the official wiki is outdated, incomplete, or uses the wrong names.
-
You can understand player-facing features like abilities, XP, and parties without having to read the source code yourself.
-
If you run a server, you can use these docs as a working reference for config files, permissions, locale text, and integrations.

For players
If you want mcMMO to feel more guided in-game, McmmoGui is a natural companion: it adds menu-driven access to skills, abilities, and other mcMMO information instead of relying entirely on chat commands.
