Common questions
What does mcMMO do?
Classic RPG skill progression for mining, combat, gathering and other normal Minecraft activities.
Is mcMMO a plugin or a mod?
mcMMO is listed here because it is used as a server plugin in its supported plugin environment. Some projects also publish builds for other platforms; use the official download page to choose the correct platform build.
Do players need to install it?
Most server plugins run server-side and do not require players to install the same JAR. Features that rely on resource packs, Bedrock bridges or optional client integrations can still change what the player must download or accept.
How do I install it?
For a supported Bukkit/Paper release, download the correct official plugin JAR, place it in the server plugins/ directory and fully restart; follow project-specific instructions for other platforms. Select an authorized release/build and back up existing skill data before upgrades; document how XP multipliers fit your economy and server progression.
How do I know the plugin loaded?
Check the startup console and logs/latest.log, then confirm the plugin loaded on its supported server platform. Next verify an actual feature rather than relying only on the plugin list: With a normal player account, perform a supported gathering activity and confirm the matching skill gains experience; reconnect and verify saved skill levels.
What if it does not load?
If the plugin failed at startup, inspect the first relevant log error for a missing dependency, incompatible Java/server version or wrong artifact. If it loaded but its feature fails: If skills never progress, inspect world blacklists, party/XP settings and permission coverage. Do not assume a plugin-load message proves every skill listener is active.
