IntruderAlerts
A client-side Fabric mod that notifies you whenever an untrusted player enters your render distance. Stay aware of who's approaching you on any multiplayer server — no server-side installation required.
Features
- Instant alerts — Get notified through three channels at once: a bold chat message, a toast popup, and an Ender Dragon growl sound
- Trust list — Mark players as trusted so they never trigger alerts. Saved by UUID, so name changes won't break it
- Safe zones — Define locations where alerts are suppressed (e.g. spawn areas, trading hubs). Zones are dimension-aware and persist across sessions
- Toggle on/off — Quickly enable or disable the mod without restarting
- Fully client-side — Works on any server. No server-side mod or permissions needed
- Persistent config — Your trust list and zones are saved to JSON files and survive restarts
Commands
All commands use the /intruder prefix:
| Command | Description |
|---|---|
/intruder trust <player> |
Add a player to your trust list (with tab-completion) |
/intruder untrust <player> |

How It Works
The mod scans nearby players once per second. When an untrusted player first appears within your render distance, you'll receive:
- A chat message:
[IntruderAlerts] PlayerName entered your render distance! - A toast notification in the top-right corner
- An Ender Dragon growl sound effect
You'll only be alerted once per player — they won't trigger repeated alerts until they leave and re-enter your range. If you're inside a safe zone, all alerts are paused.
