LuckPerms - MT Inventory Weight
by MEGATREX4
A server-side add-on from MEGATREX4 lets admins raise each player's maximum carry weight through LuckPerms ranks and users.
What it does
The add-on connects LuckPerms meta values with MT Inventory Weight. Admins set a bonus on a rank or on an individual user, and the carry capacity granted by MT Inventory Weight grows accordingly. Three kinds of bonus are read: flat maximum-weight increases, percentage increases and direct multipliers. The final capacity is calculated from the base value and the meta keys it finds.
Installation needs Fabric API, LuckPerms and MT Inventory Weight on the server. Only the server runs the add-on, so players join without installing anything. It is published for Fabric only, across 19 release versions 1.20.1 – 26.1.2, with 1.0.0+26.x for 26.1.2 as the latest file. The code is available as a public source repository, and the mod is released under the Creative Commons Attribution 4.0 license, which is not open source.
Key features
Flat weight bonuses
A meta key adds a fixed amount of maximum inventory weight to a LuckPerms rank or user.
Percentage bonuses
A meta key increases the carry capacity by a percentage, so the gain scales with the base value.
Direct multipliers
A multiplier meta key sets the capacity to a multiple of the base value for the chosen group or player.
Rank and user assignment
Bonuses can be granted to a whole permission rank or to a single user, giving admins control over both levels.

Use cases
Rewarding ranks on a server
Admins give higher-tier ranks more carry capacity, so supporters can hold more items without extra storage.
Who it’s for: Server owners who already run the required permission and inventory-weight mods and want to tie carry capacity to permission groups.
