Aluer ServerGuard V5.0
AI-Powered Comprehensive Protection System for Minecraft PaperMC Servers
Project Overview
Aluer ServerGuard is a next-generation intelligent security protection system designed for Minecraft PaperMC servers. The system features an Agent architecture with a lightweight Paper plugin serving as the data collection frontend, paired with an external Spring Boot analysis engine, delivering comprehensive real-time server protection.
Key Features:
- AI Behavioral Analysis: Anomaly detection based on Isolation Forest and time series prediction
- DeepSeek LLM Integration: Automated security alert analysis and defense strategy generation
- Full Anti-Cheat Coverage: Countermeasures against every hack module in Meteor Client and similar cheat clients
- Server Self-Healing: Automatic recovery from TPS/CPU/Memory anomalies, built-in DDoS defense
- Dual-Mode Deployment: Plugin embedded mode and External monitoring mode
- 135+ Security Modules: Covering anti-cheat, network security, host security, intrusion detection, and forensic analysis

Deployment Guide
Mode 1: Plugin Embedded Mode (Recommended)
ServerGuard runs directly inside the Minecraft server process as a Paper plugin, achieving zero network latency and maximum real-time performance.
Prerequisites:
- Minecraft PaperMC 1.21.1 server installed
- Java 21 runtime
- ServerGuard engine JAR compiled
Deployment Steps:
-
Build the plugin
cd /opt/AluerIII ./apache-maven-3.9.6/bin/mvn package -DskipTests -
Install plugin to Minecraft server
cp target/serverguard-4.0.0.jar /opt/minecraft/plugins/AluerServerGuard.jar -
Create plugin config at
plugins/AluerServerGuard/config.yml:server-url: ws://localhost:8080/agent -
Start ServerGuard engine (must start before Minecraft server)
java -jar target/serverguard-4.0.0.jar -
Start Minecraft server
cd /opt/minecraft java -Xms4G -Xmx4G -jar paper-1.21.11.jar
Upon startup, AluerPlugin will automatically connect to the ServerGuard engine via WebSocket and begin pushing Bukkit event data.
Mode 2: External Monitoring Mode
ServerGuard runs as an independent process, providing external protection via RCON and log monitoring. Suitable for scenarios where plugin installation is not desired.
Deployment Steps:
-
Build
./apache-maven-3.9.6/bin/mvn package -DskipTests -
Configure
application.ymlserverguard: mode: external minecraft: working-dir: /opt/minecraft rcon: enabled: true host: localhost port: 25575 password: "your_rcon_password_here" process-name: paper-1.21.11.jar -
Enable RCON in Minecraft
server.propertiesenable-rcon=true rcon.port=25575 rcon.password=your_rcon_password_here -
Start ServerGuard

Testing Guide
Run Full Test Suite
cd /opt/AluerIII
./apache-maven-3.9.6/bin/mvn test
Testing Conventions
This project follows strict testing discipline:
- Live Fire Testing: Tests must simulate real Minecraft server environments
- Production Alignment: Test data and behavior must match actual production environments
- Dual Constructor Pattern: Each Service class provides both a no-arg constructor (for testing) and an @Autowired constructor (for production injection)
- Static Factory Methods: Detection results use
clean(),blocked(),flagged()static factory methods - Full Suite Validation: Full test suite must pass before and after every code change

Development Guide
Quick Start
# 1. Clone repository
git clone <repo-url>
cd AluerIII
# 2. Compile
./apache-maven-3.9.6/bin/mvn compile

Requirements
| Dependency | Version | Notes |
|---|---|---|
| Java JDK | 21+ | Compilation and runtime |
| Maven | 3.9.6 | Bundled with project |
| PaperMC | 1.21.1 | Minecraft server (Plugin mode only) |
Development Conventions
See CLAUDE.md in the project root. Core principles:
- YOLO Mode: Execute directly, do not wait for confirmation
- Chinese Comments: Detailed Chinese comments on every method and critical logic, explain WHY not WHAT
- Testing Discipline: Full test suite before and after every code change
- Frequent Commits: Each meaningful change gets its own Git commit with Chinese commit messages
- Zero Pseudocode: Every line of code must be compilable, runnable, and verifiable
Performance Characteristics

| Event Throughput | 50,000+ events/sec | 10,000+ events/sec |
| Online Player Capacity | 100+ (single agent) | 100+ |
| Memory Footprint | ~50MB (plugin portion) | ~200MB (full engine) |
| Module Hot-Switching | Supported | Supported |
| Automatic Recovery | Fully automatic (self-healing) | Fully automatic |
| DDoS Defense | Multi-layer coordinated | Multi-layer coordinated |
| AI Decision Latency | ~45s (DeepSeek analysis) | ~45s |
| Use Case | Production servers (recommended) | Monitoring/backup scenarios |
