SafeWorld Plugin Overview

SafeWorld is a comprehensive security and protection plugin for Paper 1.21+ servers. A plugin specifically made for creative mode servers. It helps server administrators prevent players from exploiting game vulnerabilities, abusing abnormal NBT data, building high-frequency redstone clocks, and causing excessive entity buildup – offering all-around protection for your server.

Core Features

Item Security

Enchantment Level Limit – Blocks items with enchantment levels above the configured maximum (e.g., 32k weapons).

Attribute Modifier Filtering – Prevents items with abnormal attribute values (e.g., attack damage 255).

Custom Potion Blocking – Disallows custom potion effects, including splash, lingering, and tipped arrows with excessive amplifiers.

Command-Executing Items – Blocks books or other items that execute commands via click events.

Spawn Egg Ban – Prevents players from using any spawn eggs (including from dispensers).

Block & Entity Restrictions

Block Blacklist – Configurable list of unplaceable blocks (command blocks, barriers, structure blocks, light blocks, etc.).

Special Entity Blocking – Invisible item frames, invisible armor stands, text display entities, and block display entities are prevented from spawning.

Mob Summoning Prevention – Iron golems, snow golems (built with blocks), and chickens from thrown eggs.

Dangerous Actions – TNT ignition, ender crystal detonation, respawn anchor explosion, and wither spawning are all blocked.

Redstone / Machine Protection

High-Frequency Redstone Detection & Auto-Fix – When a redstone wire changes power too quickly, the source block (e.g., observer) is automatically replaced with a configured block (default: obsidian).

Dimension Access Control

Prevents players from entering The End or The Nether (via portals, ender pearls, commands, or any other means).

Entity Limiting & Cleanup

Per-World Entity Caps – Configure separate limits for items (drops), monsters, animals, and other entities (armor stands, minecarts, etc.).

Immediate Blocking – When a limit is reached, new entity spawns are cancelled with a notification.

Scheduled Cleanup – Automatically removes excess entities at a configurable interval.

Inventory Scanning – Periodically checks players' hands and armor slots for forbidden items and removes them.
