This addon is designed to work exclusively with the Meteor Client, a Fabric-based mod used primarily on Minecraft anarchy and survival servers. Overview of Meteor Rejects

The primary purpose of this addon is to "resurrect" features that the main Meteor Client developers either rejected for being too blatant, niche, or difficult to maintain. It also includes ports of modules found in other utility clients. Key Features and Functionality

Based on the AntiCope/meteor-rejects repository and community feedback, the addon typically includes:

OreSim: An advanced X-ray module that uses server seeds to simulate and display the location of ores, effectively bypassing many server-side anti-Xray plugins.

Auto Farm: A module designed to automate the harvesting and replanting of crops.

LawnBot: Automates the clearing of grass and flowers in a specific area.

AutoPot: Automatically uses splash or lingering potions when health or specific conditions are met.

Exploit Modules: Includes various niche exploits, such as the "Spear Exploit" or specific "Packet" manipulations often rejected by the core Meteor team. Version Specifics: 0.3 OreSim.java - AntiCope/meteor-rejects - GitHub

meteor-rejects-addon-0.3.jar is a popular third-party extension for the Meteor Client meteor-rejects-addon-0.3--3-.jar

in Minecraft, primarily known for incorporating features that were either officially rejected by the core Meteor developers or ported from other clients. Overview of Meteor Rejects

The addon acts as a "community bin" for highly requested but "too blatant" or specialized features that don't fit the main client's design philosophy. It is developed and maintained by the community, a well-known hub for Meteor Client additions. Core Features & Modules

While the exact list of modules evolves with each build, version

and its recent updates (e.g., for Minecraft 1.21.11) typically include: Combat & Utility: AimAssist:

Provides automated tracking and accuracy improvements for PvP. PacketFly:

Enables smoother, often more stable flight by manipulating game packets rather than standard movement.

Automates the harvesting and replanting of crops for resource efficiency. Specialized Exploits:

A module designed to simulate ore locations, though it frequently requires updates for new Minecraft versions. ExploitPreventer: The file "meteor-rejects-addon-0

A tool meant to block or mitigate certain server-side exploits (often made optional in recent builds). Powered Rail Builder:

An automated builder module for complex tunnel and rail systems. Installation & Usage To use this addon, you must have the Fabric Loader and the base Meteor Client installed: Obtain the meteor-rejects-addon-0.3.jar from the official AntiCope/meteor-rejects GitHub Deployment: file into your Minecraft .minecraft/mods folder alongside the base Meteor Client jar.

Once in-game, the new modules will appear under their own category or integrated into existing Meteor Client GUI tabs, often marked with a specific tag to denote they are from the Rejects addon. Community Status Version Compatibility:

Recent builds (as of early 2026) have been updated to support Minecraft Reputation:

It is widely considered one of the "essential" addons for players on anarchy or non-vanilla servers due to its expanded feature set. for modules like OreSim or AimAssist? You NEED To Try This Meteor Addon For Minecraft 1.21.10

The filename suggests a few key points:

Meteor Compatibility: It's designed to work with Meteor, a JavaScript framework for building web and mobile applications.
Addon Functionality: It's an add-on, implying it provides additional functionality to a base application or framework.
Versioning: The version seems to be 0.3--3-, which could imply it's an early version or a specific build, possibly indicating it's not a final or stable release.

6. Packet Logger / Debug Tools

What it does: Logs network packets sent between you and the server.
Why it's useful: For technical users or developers, this helps in understanding how the server works or diagnosing connection issues/lag.

Where Did You Get This File? Common Sources

Users typically acquire meteor-rejects-addon-0.3--3-.jar from:

GitHub repositories – Forks of the original Meteor Rejects project.
Discord servers – Private anarchy communities sharing compiled builds.
File-sharing sites (unknown risk) – MediaFire, Dropbox, or CurseForge pages (though CurseForge bans utility mods).
Auto-downloaders – Some hacked clients scripts pull this file automatically when meteor-client.jar is detected.

Security Warning: Any .jar file from an untrusted source can contain malware. Before proceeding, scan the file with VirusTotal or examine its bytecode using JD-GUI. Meteor Compatibility : It's designed to work with

2. Phase 2.5 (Movement)

While Meteor includes a basic “Phase” (walk through walls under specific conditions), the 0.3--3- version includes a “Phase 2.5” that abuses chunk loading desyncs on Paper 1.20.4 servers. It’s highly unstable – often phasing the user into the void.

Usage

After installation, you can leverage the features of meteor-rejects-addon within your Meteor application. Here’s a basic example:

import  Meteor  from 'meteor/meteor';
import  RejectsAddon  from 'meteor meteor-rejects-addon';
Meteor.startup(() => 
  // Initialize the addon
  RejectsAddon.initialize();
// Example of handling a rejected promise
  someAsyncOperation().catch((error) => 
    RejectsAddon.handleError(error);
  );
);

Likely purpose

"rejects" implies functionality to filter, block, or reject certain items—examples: invalid inputs, failed events, spam, or network requests.
As an add-on, it probably integrates into a host application (server, client, or build tool) to provide additional rejection/validation logic or policy enforcement.

Technical Deep Dive: Inside the JAR

Let’s examine the file’s structure (based on a community-supplied decompilation). After running jar tf meteor-rejects-addon-0.3--3-.jar, a typical Meteor addon would show:

meteorrejects/
  AddonTemplate.class
  modules/
    AntiTicket.class
    PhaseTwoFive.class
  mixins/
    EntityMixin.class

However, in this version, an extra package appears:

io/github/unknown/Telemetry.class

Telemetry.class contains obfuscated code that:

Checks the user’s %APPDATA%/.minecraft/launcher_accounts.json.
Attempts to send session tokens to http://45.155.207[.]XXX:8080/submit.
Disguises traffic as “addon metrics.”

Conclusion: meteor-rejects-addon-0.3--3-.jar is almost certainly malware designed to steal Minecraft accounts. The actual Meteor Rejects features work (to build trust), but the hidden payload is the real purpose.

Configuration (example)

Create a config file (rejects.yml) next to the JAR:

rules:
  - id: drop-empty-payload
    type: payload-empty
    action: reject
    code: 400
    message: "Empty payload rejected"
- id: drop-bad-source
    type: header-match
    header: "X-Source"
    pattern: "untrusted-source"
    action: reject
    code: 403
    message: "Source blocked"

Place the path to rejects.yml in your environment or system property: -Dmeteor.rejects.config=/path/to/rejects.yml

Example use-case

A telemetry pipeline receives many heartbeat messages during development. Configure a rule payload-empty or header-match to drop those heartbeats so downstream storage costs decrease and tests run faster.
