Plugin BlockLocker

BlockLocker chest and door protection

BlockLocker is a lightweight protection plugin for your Minecraft server that secures chests, doors, furnaces, hoppers and other containers simply by placing signs. Once a sign is attached, only the players or groups listed on it can interact, while all data stays stored directly on the sign instead of a database, which keeps performances stable and compatible with tools that move blocks.

The plugin is fully UUID compatible, so players keep access even if their name changes, and it handles double chests, double doors, redstone and automatic door closing. At BoxToPlay, we recommend it for survival and faction style worlds where intuitive, sign based protection is essential.
