Catch the dupe on the click that makes it.
Put a watch on a suspect and every item they hold gets its own hidden ID. A dupe copies the ID too, so the second copy gives itself away the moment it reaches their hands.
Bundles, shulkers, the cursor, donkeys, item frames and crafters are all checked. Players without a watch are never tagged and cost nothing.
Not just punishments. Investigation.
Every player has a case: notes, reports, flags, punishments and accounts on the same IP. It sits one search away, next to a live map of where they are right now.
Cheat detection reads GrimAC flags, packet alerts, x-ray ratios and client brands, then puts it all on one page instead of in pop-ups.

Ranks that tell you why.
MMaRP is a full permission plugin. It reads every plugin’s plugin.yml, so each node has its description and default, and the checker shows which rule decided the result.
Moving over? Import from LuckPerms, PermissionsEx or MMaRP v4.
One jar instead of seven.
Permissions, punishments, chat moderation, staff tools and a live map usually mean a folder of plugins that don’t talk to each other. MMaRP keeps all of it in one place, on one player page.
Moving over keeps your data: import groups from LuckPerms and bans from LiteBans, AdvancedBan or vanilla.

Run the server from the browser.
The dashboard runs on your game port, so there’s nothing extra to host or open. Log in with a one-time link from /mmarp web.
Lock, restart or shut down with a 6-digit code to retype, so nobody does it by accident. Every staff action lands in a protected audit log.
From 1.8.8 to 26.3.
Install the jar for your version and start the server. MMaRP works out what it’s running on and turns on the rest by itself.
| Server version | Spigot | Paper | Folia |
|---|---|---|---|
| 26.3MMaRP, Java 25 | Yes | Yes | Yes |
| 1.21.1 to 1.21.11MMaRP, Java 21 | Yes | Yes | Yes |
| 1.20 to 1.20.6MMaRP, Java 17, or 21 from 1.20.5 | Yes | Yes | Yes |
| 1.16.5MMaRP, Java 8 or newer | Yes | Yes | No |
| 1.8.8MMaRP Legacy, Java 8 | Yes | Yes | No |
Folia support covers the versions Folia publishes builds for. Older versions only skip what the game doesn’t have, like shulkers on 1.8.8 and crafters on 1.16.5.
Running a network?
Add MMaRP-Velocity to your Velocity 3.x proxy. It becomes the brain of the network and the dashboard moves there, so one login covers every server. Without it, each server runs on its own.
- Banned players are stopped at the proxy
- Alt detection sees the whole network
- Permissions sync to every server
- Staff can follow players across servers
- Lock one server or all of them
- SQLite still works, only the proxy writes
Finds your server type
MMaRP is built on the Spigot API and detects Paper and Folia when it starts. Extras switch on only where they exist.
Safe on Folia
All scheduling goes through one layer that picks the right region or entity scheduler, so nothing runs on the wrong thread.
Light on the server
The database never runs on a game thread, and the map stops rendering when TPS drops below 18.
