X-SHIELD is a server administration utility for NeoForge 1.21.1 that helps server operators detect and monitor unauthorized client modifications and resource packs.

Features:

Detects unauthorized client modifications and resource packs (such as X-Ray texture packs) when a player joins the server
Sends a detailed alert to all online operators including the player's name, UUID, and the name of the flagged modification
Clickable [Spectate] button — instantly sets the operator to Spectator mode and teleports them directly to the suspect
Clickable [Shame] button — broadcasts a public server-wide message exposing the player for using unauthorized modifications
Clickable [ModList] button — shows the operator the suspect's full installed mod list and active resource packs at a glance
Writes per-player audit logs to logs/X-Shield PlayerLogs/<PlayerName> (UUID).txt — every session is recorded with the player's full mod list, so admins can review history even if no operator was online at the time
Optional Discord Webhook integration to receive real-time alerts directly in a Discord channel
Fully configurable via xshield-server.toml — operator permission level, Discord webhook URL, custom detection keywords, and a whitelist for legitimate mods whose names may trigger a false positive
Requires installation on both client and server — players without the mod cannot join the server

How it works: When a player connects to the server, X-SHIELD collects their installed mod list and active resource packs and sends them to the server. The server then matches them against a configurable keyword list. If a match is found, all online operators are immediately notified with a detailed, interactive alert message.

Note: X-SHIELD is a first-line detection and administration tool designed to assist server operators. It is not a substitute for server-side anti-cheat solutions and is intended to be used alongside them. Operators are encouraged to verify suspicious activity manually before taking action against a player.
