SunAntiCheat (SunGuard)

Anti-cheat plugin for Minecraft 1.21 servers running Paper, paired with a web admin dashboard. In game, it detects X-Ray through mining statistics, Freecam and Kill Aura (reach, angle, line of sight, clicks per second), and provides sanctions, a block log with rollback, player reports and staff alerts in game and on Discord. The plugin embeds an HTTP and WebSocket server with JWT authentication, roles, TOTP two-factor and login rate limiting, serving a React dashboard of more than 40 pages: live console, players, economy, quests, crates, analytics, backups. An AI assistant queries Gemini or OpenAI to diagnose the server. The repository holds more than 300 Java files, with releases automated through GitHub Actions.
