Because MTA is open source, it is possible for people to create their own customized versions. Does the MTA client prevent fraud? If the answer is yes, how? Is there a positive use case? For example, a developer version of the mta client for personal use

just fun

MTA:SA - Claire Anticheat Claire is a modular, lightweight anticheat resource for MTA:SA, designed to improve the integrity and fairness of servers. Its core philosophy is simple: organize detections into clean, independent modules, make them easy to configure, and build an open platform that others can expand and improve. Claire runs silently in the background, acting as a guardian layer — constantly monitoring player behavior, network conditions, and client-side integrity without interfering with gameplay or degrading performance. Its design favors discretion and precision, targeting cheats without disrupting legitimate users. If you're looking for a solid, customizable way to secure your MTA:SA server, try out Claire. Why does it matter? By being fully open-source, Claire gives server owners an accessible and transparent tool to detect common exploits and improve their server environment. But more than that, it invites collaboration. The idea is that, together — through testing, feedback, improvements, and shared knowledge — we can create a more solid, trustworthy anticheat resource that benefits the entire MTA community. Current features Claire currently includes over 20 independent detection modules, covering movement, combat, environment manipulation, network spoofing, and more. All detections are modular, configurable, and designed to operate silently in the background with minimal performance impact. False positives are rare thanks to tolerance-based logic, score systems, and heuristic analysis. Overall reliability across all modules is expected to be around 95%, all features are listed at our GitHub page. Contributing Claire is an open-source project — contributions are welcome!

Hello everyone I hope you're having a great day, I noticed that there's been more and more cheaters everyday using fly hacks, speed hacks, serial spoofers etc. On the server I play everyday which is The Favoured Few there's been 10 cheaters banned already from the server in the last 2 days and the server is DM/HDM focused which is even more crazy because its not a RPG server or anything like that and its "suppose" to have less cheaters since there isn't really any point to cheat in HDM/DM unless you want to pass a map faster etc. Please someone from Anti Cheat staff do something about this since its starting to get annoying. Thanks. @Dutchman101 Here's a link to a video where it shows 1 of many cheaters playing with the hack:

English; ● Hello, good forums, my server with freeroam game mode uses the newly released cheat, and now I've seen 2 people, there is video proof of this cheat. I demand punishment. -Video: [removed] [removed] [2022-03-27 10:49:05] LOGIN: (Everyone) [removed] successfully logged in as '[removed]' (IP: [removed] Serial: [removed]) [2022-03-28 22:39:02] LOGIN: (Everyone) [removed] successfully logged in as '[removed]' (IP: [removed] Serial: [removed])

Hello, dear MTA:SA Developers! I wanna report you one BIG problem in AC which may break Destruction Derby and DeathMatch gamemodes (race). This mistake allows some players change config of cars and make cars much more dynamic and gives them very good control of it. This video shows how do players play with it. (Yes, they exist already and play ClanWars! You may see their nicknames on the video + turk teamchat below). If you don't take any actions we will get really big problems with it. AC doesn't detect anything. P.S. I've sent another video (how to use it) to ccw and hope he will take care of it.
