MC Verificator (MCV) is a client-side program for verifying the integrity of a local Minecraft installation. MCV checks for suspicious files, loaded classes, and active connections to determine if a client is using cheats or disallowed add-ons. A final report is then visible on-screen as well on this website.

Never trust a report that is published by anyone other than the source subject. It is advised to supervise the source subject during the runtime of MCV.
