MPDS
by Nekozuki0509
MPDS is a Fabric server-side mod that syncs player data between Fabric servers, so players keep their progress as they move across a network.
What it does
MPDS moves player data between Fabric servers. Only the server needs the mod, so players join without installing anything on their own game. The mod requires Fabric API, which must also be present on the server.
Server owners place the mod in the server's mods folder and restart the server to apply it. Installation is a single step for each server in the group, and the README in the public source repository covers the setup.
Builds cover 1.18 – 1.21.11 with 27 release versions, and the latest Fabric file is 4.2.0 for 1.21.11, published 2026-08-28. The mod was first published on 2024-02-18 and is released under All rights reserved, so the code is not open source.
Key features
Player data sync
Player data is passed between Fabric servers, so a player's progress carries over when moving between them.
Server-only installation
The mod runs on the server alone, and clients need nothing extra to join the network.
Simple setup
Placing the file in the server mods folder and restarting the server is enough to start syncing.
Public source and wiki
A source code repository, an issue tracker and a wiki are linked for anyone who wants to read the code or report a problem.

Use cases
Server networks
Groups of Fabric servers that share one player base can keep each player's data consistent across all of them.
Who it’s for: Server owners who run several Fabric servers and want players to keep their data as they move between them. Players on a single server have little use for it.
How it compares
Pack Sync is a client-side only Fabric mod for 1.21.4 under All rights reserved, so it is installed by players rather than servers. XP Limiter is server-side only, released under the MIT License and published for 1.20.1 – 1.21.5, so it changes experience on the server alone. HorizonSync is server-side only under the Apache License 2.0 and targets 1.21.1, which is a narrower target than the full build set of this mod.
