ModChecker is a utility mod that ensures only approved mods can run on your Minecraft client.
It is designed for servers or modpacks that want to enforce a strict list of allowed mods.
✨ Features:
- Blocks unauthorized or unapproved mods from running.
- Ensures players have all required mods installed before launching.
- If players install more or fewer mods than required, Minecraft will not launch and will crash.
- Useful for server owners who want to keep gameplay fair and consistent.
- To make this mod compatible with your server, you must also install the AntiModPlugin plugin on the server.
With ModChecker, you can make sure everyone uses the correct mods, improving stability, security, and fairness.
