🏰 FortressCore

The Ultimate Security & Administration Suite for Minecraft Servers

FortressCore is a battle-tested, all-in-one server protection plugin built for server owners who take security seriously. From AI-powered threat detection to per-role permissions — everything you need to run a safe, well-managed server is in one place.

⚡ Offline-mode friendly · 🤖 Gemini AI powered · 🔒 BCrypt encrypted · 📋 Fully configurable

🤖 AI-Powered Security

Gemini 3.5 Flash Integration

FortressCore's AI engine runs 7 independent security modules — all async, all rate-limited, all falling back to rule-based logic if the API is unavailable. Set your API key and let it run.

Module What it does
🔍 Join Threat Analysis Profiles every connecting player and auto-kicks or bans critical threats
🔑 Login Anomaly Detection Flags account takeover attempts via IP region and time fingerprinting
💬 Chat Moderation Scans every message for toxicity, ads, scams and auto-executes actions
⌨️ Command Abuse Detection Catches exploit probing and permission escalation in real time
👁️ Watchlist Automation Monitors flagged players and delivers an AI verdict after a watch period
📜 Ban Appeal Review Reads player appeals and recommends deny / reduce / pardon to owners
📊 Security Reports Scheduled threat summaries with trend analysis broadcast to online owners
  • All Gemini prompt templates are editable in config.yml
  • Daily quota tracking — automatically pauses AI at Google's free-tier limit and resumes at UTC midnight
  • Circuit breaker — stops retrying on quota exhaustion instead of spamming your logs
  • Full rule-based fallback when AI is unavailable or disabled

🔒 Security Features

🪪 Login & Account Protection

  • Mandatory login / registration system with BCrypt password hashing
  • Anti-impersonation — username-based password locking so no one can join as someone else on offline-mode servers
  • Configurable session durations — set once per day, per hour, or never expire
  • Two-Factor Authentication (2FA) with time-based codes
  • Login attempt limits with automatic temporary IP bans
  • everytime_login toggle — choose whether players re-authenticate on every join

🛡️ Anti-Hack & Anti-Bot

  • Lockdown Mode — auto-activates on join spikes, manually togglable
  • VPN / Proxy detection via proxycheck.io with configurable actions
  • IP whitelist & blacklist management
  • Username blacklist with regex pattern matching
  • Anti-spam chat protection with auto-mute
  • Anti-flood and fast-reconnect detection with auto-ban

🔑 Access Control

  • Multi-owner system — separate from vanilla op, immune to all security checks
  • FortressCore op management — your own op tier independent of Minecraft
  • IP history tracking per player with full audit trail

👑 Role System (New in 1.0.4)

A fully featured permission and display tier system built into the plugin — no external permissions plugin required.

  • 4 built-in roles — OWNER · ADMIN · MODERATOR · MEMBER
  • Create unlimited custom roles (VIP, Builder, Trusted...) in config.yml
  • Per-role chat color, name color, prefix, suffix, and priority
