## What is it?<\/p>\n
The Axion Paper plugin is the multiplayer companion for the Axion Fabric mod on Paper servers. It validates edits, applies larger operations server-side, records history, and keeps advanced building tools working correctly on Paper.<\/p>\n
For the client-side toolset, install the Fabric mod:<\/p>\n

If you are running a Fabric dedicated server instead of Paper:<\/p>\n
– Fabric dedicated server support exists only for Minecraft `1.21.11`
\n– it does not use this plugin
\n– it uses the same main Axion Fabric mod jar in the server `mods` folder<\/p>\n

## Overview<\/p>\n
The Paper plugin is what makes Axion authoritative in multiplayer on Paper.<\/p>\n
It handles:<\/p>\n
– server-backed edit application
\n– write and clipboard validation
\n– per-player history with undo and redo
\n– large edit transport
\n– server-side policy checks
\n– multiplayer-safe tool behavior<\/p>\n
If you are only using Axion in singleplayer, you only need the Fabric mod.<\/p>\n
If you want Axion edits to work properly on a Paper server, you need this plugin too.<\/p>\n

Axion currently supports `1.21.5 – 1.21.11` & `26.1.x` for the fabric client and paper server.
\nDedicated fabric server is currently only supported for `1.21.11`.<\/p>\n

\n– Validation for edit limits and region safety
\n– Large-operation transport chunking

## Requirements<\/p>\n
For Paper:<\/p>\n
