ModChecker
by Tubs Pluginz
ModChecker, a Fabric utility by Tubs Pluginz, compares the mods installed on a client against a list of allowed mods fetched from a repository.
What it does
On startup the mod reads the mods installed on the client and checks them against an allowed list that it retrieves from a JSON file kept in a GitHub repository. Any mod that is not on that list is reported as unexpected. The mod runs on the client only and needs Fabric API, and it is released under the MIT License as open source for 1.20 – 1.21.10.
Key features
Allowed mod list
The allowed list is a JSON file in a repository, so the list can be changed without updating the mod itself.
Unexpected mod report
Mods that are installed but missing from the allowed list are flagged and named in the game.
Server-defined rules
The list comes from the repository the server owner points to, so the rules follow that owner's choice.
