Just make sure you're using the version that matches your Minecraft version (e.g., 1.20.x) to avoid startup errors.
Detection: While clients themselves are hard for servers to "see" via protocol, using the aggressive modules in Rejects (like rapid movement or high-speed combat) is highly detectable by anti-cheat plugins.
Instead, look for a maintained fork of Meteor Rejects from a reliable GitHub repository with semantic versioning (e.g., rejects-addon-1.2.0.jar). Always compile from source if possible.
