MOG-ANTICHEAT

MOG-ANTICHEAT is a free, self-hosted plugin for Spigot and Paper Minecraft servers that targets common PvP cheats. It suits operators maintaining the older 1.8.9 environment who want direct checks, alerts and blocking without a subscription. Its focused scope and compatibility warnings make it a weaker choice for newer servers or investigations that depend on replay evidence.

Overview

The plugin addresses several categories of abuse that matter in competitive play: combat automation, movement advantages, building exploits and packet spam. Administrators can toggle checks and respond to detections, while permitted staff can receive alerts. That is a useful operational baseline for a small or medium server, but replay analysis is not included, so reviewing a disputed incident still depends on other moderation evidence.

Installation follows the conventional Spigot workflow: place the downloaded JAR in the server's plugins folder and restart. Downloads are linked through PaperMC Hangar, SpigotMC and GitHub. The public repository includes source code and compilation instructions, and the PaperMC listing identifies the project as GPL-licensed. Those distribution and source options help operators who want to inspect or compile the plugin instead of using only a packaged build.

Key features

Detection covers Killaura, Reach, Speed, Spider, Timer, Scaffold, Destroyer and PacketSpammer. In practice, that gives a PvP server coverage across combat, movement, rapid-action and packet-related behavior rather than a single-purpose check. Detected hacks can be blocked, violation alerts can be issued, and individual checks can be switched on or off.

The mogac.admin permission opens the full command set: /mogac help, /mogac checks, /mogac toggle <check>, /mogac alerts and /mogac reload. The mogac.alerts permission is for staff who need detection notifications, while mogac.bypass allows designated users to bypass checks. These permissions support separated administration, monitoring and exemptions, although the project warns that bugs may exist.

Pricing

MOG-ANTICHEAT costs free. There is no paid tier or free trial, so every supported server gets the same published feature set and there are no subscription renewals to manage. The trade-off is that the free package comes with the project's stated bug caveat and does not add replay analysis or a broader support tier.

Platforms

This is self-hosted software for Spigot and Paper. The listed compatibility range is Minecraft 1.8–1.12.2, with testing cited for 1.8.9 and 1.12.2. The maker cautions that 1.12.2 may contain more bugs than 1.8.9, making 1.8.9 the safer target when choosing between those versions. Servers on newer Minecraft releases should look elsewhere rather than assume compatibility.

Who it's for

Choose it if you run a Spigot or Paper PvP server centered on Minecraft 1.8.9 and want configurable enforcement without a paid plan. It is also a reasonable fit for operators comfortable managing plugin files, permissions and command-based configuration. It is not the right match for a modern 1.20-era server, a team requiring replay-based investigations, or an operation that cannot tolerate compatibility uncertainty.

Pros and cons

Pros

• Free with no trial expiry: the complete published plan costs nothing and has no renewal decision.
• Broad basic check set: eight named checks cover combat, movement, building and packet abuse.
• Direct administration: toggles, reload, alerts and permission-separated access provide practical server controls.
• Inspectable distribution: GPL licensing and public source code support review and self-compilation.

Cons

• Narrow version focus: compatibility stops at the listed 1.12.2 range, with extra bug risk on 1.12.2.
• Known bug caveat: the project itself warns that bugs may exist, so enforcement needs monitoring.
• No replay analysis: the plugin cannot provide replay-based evidence for contested punishments.

Alternatives

Browse Minecraft Anti-Cheat Plugins for a wider category comparison. Pick MLSAC instead if you want a freemium option with web and Windows platforms and a free Beginner plan that includes its Mini model. AntiGuard is the better alternative for Paper or Purpur 1.20.x on Java 17, with API, web and self-hosted deployment under an MIT license. Choose CheckHacks for an always-free self-hosted and web option with donations optional.

GuardAC suits readers seeking a freemium API or web service with a free tier and trial. Intave offers a free self-hosted/web tier with movement and combat cheat detection, but no combat automation detection, build automation detection or priority support. Shard is a freemium, fully open-source alternative with a free plan limited to five credits per month. Advanced Anti-Cheat is another free self-hosted project distributed through a public GitHub repository. For newer Paper, Spigot or Folia servers on Minecraft 1.17.x–1.21.x, ExploitShield targets that range but requires Java 17+, PacketEvents 2.13.0+ and ProtocolLib 5.4.0+.

Verdict

MOG-ANTICHEAT is a sensible zero-cost choice for a 1.8.9-focused Spigot or Paper PvP server that needs named checks, immediate blocking and permission-controlled alerts. Choose it for straightforward local enforcement and public source access; look elsewhere if your server runs newer Minecraft, if compatibility risk is unacceptable, or if replay analysis is central to your moderation process.
