Bad Mod Tags

A community database of Minecraft mods with incorrect client/server compatibility tags on CurseForge and Modrinth.

Mislabeled mods cause real problems. Client-only mods marked as server-compatible can crash servers or waste resources, while server-required mods marked as client-only lead to failed connections. This database provides the correct tags so launchers and modpack tools can handle these mods properly.
