ShopGuard

Land-claim grief protection for Fabric. Claim land with a golden shovel and carve it to any shape, protect it from players and the environment, and let admins control where claiming is allowed. ShopGuard is fully server-side — players connect with a vanilla client and are protected automatically. Works in single-player too.

Features

Carve-to-fit claims. Right-click two corners with a golden shovel to claim a rectangle, right-click the air to switch to carve mode, then trim it to any shape. Touching claims merge into one.
Real protection. Non-owners can't break or place blocks, open containers, or disturb item frames, armor stands, or paintings inside a claim.
Shops stay open. Visitors can still use doors, gates, trapdoors, and pressure plates to walk through, and trade with villagers — so a claimed shopping district keeps working. Buttons and levers are blocked for visitors by default (configurable).
Environmental protection. Claimed blocks survive explosions (TNT, creepers, ghasts, end crystals, wither, beds/anchors), fire, piston pushes, and fluids flowing across the border.
Admin zones. Ops mark where players are allowed to claim with a golden hoe (or a command). With no zones set, players can claim anywhere.
See what's claimed. /claim show outlines everything nearby with particles — your claims in green, other players' in orange, and admin zones in dark red — so you always know what land is taken.
Trust. Give friends full build access to your claim.
Configurable limits. Cap the size of a single claim and the total per player.

Commands

Command	Who	What
`/claim`	anyone	Your claims and how much you've used
`/claim show`	anyone	Toggle the claim/zone outlines
`/claim remove`	owner	Remove the claim you're standing in
`/claim trust <player>`	owner	Toggle a player's build access
`/claim zone add \| list \| remove`	ops	Manage the zones players may claim in

Getting started

Grab a golden shovel and right-click two corners to make your first claim.
Right-click the air to toggle carve mode and trim the claim to fit.
Use /claim show to see claim and zone borders around you.

OP's can either use the command or a golden hoe in the same way as the shovel to claim the "claim district's land"
