CheckYourMods 🛡️

CheckYourMods is an advanced security and transparency tool for Minecraft 1.21.1 (NeoForge) designed for server administrators. Specifically designed for friends' servers to ensure that no one is downloading suspicious mods that aren't necessary to play or cheating. It ensures a fair play environment by monitoring client-side modifications and resource packs.

✨ Key Features

Smart Mod Verification: Automatically compares player mods against the server's mod list and ignores matches.
Intelligent Resource Pack Scan: Detects suspicious keywords like "xray", "vision", or "transparent" within the pack's internal metadata (pack.mcmeta).
SHA-256 Fingerprinting: Allows manual tracking of specific resource packs using their unique digital hash.
Transparency for Players: Includes public commands so players can verify what is being monitored, ensuring the staff is not hiding anything.
Persistent Logging: All connection data, detected mods, and suspicious packs are recorded in logs/checkyourmods-log.txt.

🛠️ Configuration

The mod generates a configuration file in serverconfig/checkyourmods-server.toml with intuitive instructions:

allowed_mod_ids: Add IDs for client-side utility mods (e.g., optifine, sodium, voicechat) so they are not announced as extra mods.
manual_xray_hashes: Add specific SHA-256 hashes for malicious packs that might bypass the keyword scanner.

💻 Commands

/modcheck list: Shows the list of allowed mod IDs to all players.
/modcheck packs: Shows the list of manually watched resource pack hashes.
