Valheim ServerGuard

A single mod that handles the messy parts of running a dedicated Valheim server with a curated modpack: mod allowlist, anti-cheat, moderation tools, Discord integration, and forensic logging — all configurable from YAML.

What it does (in plain English)

Locks your server to a specific modpack. Players running the wrong mods are kicked at the door.
Blocks common cheats. devcommands / god / fly / spawn and other console cheats are silently neutered. Emote attack-cancel exploit is blocked. Suspicious movement speed and skill levels are flagged.
Sends events to Discord. Public channel for player events (joined / kicked / died / shouts / raid alerts). Optional admin channel for moderation events (violations / config reloads / daily summary).
Announces raids by their real name. Random-event raids are posted to Discord using the in-game event name (e.g. "The Horde Is Attacking") with coordinates, plus pause/resume/end updates.
Strips cheat items on login. Configured items (SwordCheat, SledgeCheat by default) are removed from non-admin players' inventories when they join.
Provides admin commands in the game console. Open the F5 console, type sg help. Kick, pardon, query the build log, hot-reload config — without leaving the game.
Records build / destroy events to CSV. Useful when investigating grief reports.

Quick setup

Install this mod on your dedicated server.
Install Valheim_ServerGuard_Client on every player's machine.
Launch the server. It writes BepInEx/config/ServerGuard/conf/settings.yaml with a random sharedSecret.
Copy that sharedSecret value. Each player pastes it into their BepInEx/config/ServerGuard/client.yaml.
Add your modpack to BepInEx/config/ServerGuard/conf/allowed_mods.yaml. The companion plugin generates a ready-to-paste snippet at mods_for_allowed_mods.yaml after a player runs Valheim once.

That's the minimum. Everything else is optional.
