Chest SignLock

Chest SignLock is a server-side Fabric mod that lets players protect containers and doors using signs.

It is designed to be simple, lightweight, and easy to understand for players: place a sign, write who is allowed, and the block becomes private.

Chest SignLock is heavily inspired by the classic Spigot plugin BlockLocker, adapted for modern Fabric servers.

Place a sign on a supported block to lock it.

A private sign uses:

[Private]
PlayerName

[More Users]

If a block has a valid [Private] sign, only listed players and server operators can interact with it.
