About this Mod
IntruderAlerts is a client-side Fabric mod that notifies you when random untrusted players appear nearby. When an unknown player enters your render distance, you'll receive a chat message, a toast notification, and a sound alert.

You can manage a personal trust list to suppress alerts for friends and known players, and set up ignore zones in areas like spawn or trading hubs where alerts would be too frequent. All settings are stored locally per-client.
Features:
- Chat, toast, and sound alerts when untrusted players appear nearby
- Per-player trust list (/intruder trust, /intruder untrust)
- Ignore zones to suppress alerts in specific locations (/intruder zone add, /intruder zone remove)
- Toggle alerts on/off (/intruder toggle)
- Translated into 13 languages
- Fully client-side — no server installation required
