Saros Mod Checker

The Saros Mod Checker is a server-side mod that verifies client mods and resource packs when players join your server. It checks all installed mods and active resource packs against a configurable blacklist, automatically disconnecting players who have forbidden content installed.

• Mod Verification 🔍
• Automatically scans all client mods when players join the server.

• Resource Pack Checking 📦
• Validates active resource packs alongside mods for complete content verification.

• SHA-256 Hash Verification 🔐
• Uses secure SHA-256 hashing to identify mods and resource packs by their exact content.

• Configurable Blacklist ⚙️
• Easy-to-edit JSON configuration file to manage blacklisted mod names and hashes.

• Automatic Mod List Export 📋
• Exports the server’s mod list to modlist.md on server startup.

• Instant Kick Protection 🛡️
• Players with blacklisted mods or resource packs are immediately disconnected with a clear message.

• Server Setup: Install the mod on your server – it will automatically create a default blacklist config.
• Client Requirement: Players must have Saros Mod Checker installed to join the server.
• Blacklist Configuration: Edit config/sarosmodchecker-blacklist.json to add mod names or SHA-256 hashes.
• Verification Process: When a player joins, their mods and resource packs are automatically verified.

• /checkclientmods <player>: View all mods and resource packs installed on a connected player’s client. (OP Level 2 required)
