DupeDetection Plugin

A powerful Minecraft Paper plugin designed to detect and prevent item duplication exploits on your server.

• Checks all storage containers: chests, barrels, hoppers, furnaces, etc.
• Counts total items across ALL inventory slots

? NBT Duplicate Detection

• Identifies suspicious identical items with same enchantments/modifications
• Individual configuration per item type
• Smart detection: only flags items with special NBT data (duplicate enchants, names, etc.)
• Catches duplication of gear & items

? Discord Integration

• Discord webhook notifications with embeds
• @everyone mentions
• Detailed violation reports with player info, location, and teleport commands
• Puts multiple violations from same container into single message

⚡ Exception System

• Excempts specific players or UUIDs from all dupe checks
• JSON storage for persistent exceptions
• Easy management through in-game commands
• Tab completion

• Java Version: 21+

? How It Works

Detection Triggers

• Storage Container Close: Chests, barrels, hoppers, furnaces, etc.
• Player Inventory Close: When players close their inventory (5-second cooldown)

Detection Process

1. Player closes container/inventory
2. System scans all items in the inventory
3. Checks against configured limits and NBT patterns
4. Sends Discord notification if violations found
5. Notifies online operators

Stealth Operation

• No player notifications - violators are unaware of detection
• Silent monitoring - only admins receive alerts
• logging - all activity tracked

? Discord Notifications

Embeds notifications include:

• Player Information: Name, UUID, avatar
• Violation Details: Item types, amounts, limits exceeded
• Location Data: Exact coordinates and world
• Quick Actions: Teleport command
• Container Info: Type of storage block involved
