PaperMC AI Operations

Manage PaperMC Minecraft servers through safe, controlled interfaces. Use for server lifecycle management, backups, plugin operations, and health monitoring with backup-first safety policy.

PaperMC Server AI Operations

AI-managed PaperMC Minecraft server operations with safety-first approach.

When to Use This Skill

Use this skill when you need to:

• Manage PaperMC server lifecycle (status, logs, restart)
• Create backups (world, plugins, PaperMC jar)
• Install or update plugins safely
• Update PaperMC server version
• Monitor server health and diagnose issues
• Intelligent plugin upgrades with risk assessment (NEW in v2.0)

Requirements

• Linux system with systemd
• Java 21+ (Zulu JDK recommended for ARM)
• Python 3.10+
• PaperMC server installation

Quick Start

1. Configure

Edit paths in the scripts:

python

# In manage_server.py, plugin_manager.py, update_paper.py
SERVER_DIR = Path("/path/to/your/papermc-server")

2. Check Status

bash

python3 manage_server.py status

3. Create Backup

bash

python3 manage_server.py backup

Core Scripts

manage_server.py

Server lifecycle management:

bash

python3 manage_server.py status          # Service status
python3 manage_server.py logs -n 50      # View logs
python3 manage_server.py backup          # Backup world
python3 manage_server.py restart         # Safe restart

plugin_manager.py

Plugin operations:

bash

python3 plugin_manager.py list                           # List plugins
python3 plugin_manager.py backup <plugin.jar>           # Backup plugin
python3 plugin_manager.py install-url <url> --filename <name>

update_paper.py

PaperMC updates:

bash

python3 update_paper.py backup-jar                    # Backup current jar
python3 update_paper.py update-from-url <paper_jar_url>

plugin_upgrade_framework.py (NEW in v2.0)

Intelligent plugin upgrade framework with risk assessment:

bash

# Upgrade specific plugin (Method 1)
python3 plugin_upgrade_framework.py --plugin ViaVersion --version 5.8.0

# Scan for upgrade candidates (Method 2)
python3 plugin_upgrade_framework.py --method 2 --scan-limit 20

# Run examples
python3 upgrade_examples.py

Safety Rules

❌ Never Use Direct Commands

• kill, kill -9
• rm -rf
• systemctl stop/restart
• Direct file overwrites

✅ Always Use Scripts

All operations go through approved Python scripts.

📦 Backup-First Policy

Before ANY risky operation:

1. Run backup command
2. Verify backup created
3. Proceed with change

Plugin Upgrade Framework (NEW in v2.0)

Based on ViaVersion 5.7.2 → 5.8.0 upgrade experience (2026-03-28), this skill now includes an intelligent plugin upgrade framework.

Core Upgrade Methods

Method 1: Specific Plugin Upgrade

For upgrading a specific plugin with full automation:

python

from plugin_upgrade_framework import PluginUpgradeFramework

framework = PluginUpgradeFramework()
result = framework.method1_specific_plugin_upgrade("ViaVersion", "5.8.0")

Method 2: Scan and Assess Upgrades

For periodic maintenance and batch upgrade planning:

python

result = framework.method2_scan_and_assess_upgrades(limit=20)

Risk Assessment Logic

Risk Level	Version Jump	Action
Low	Patch update (x.x.1 → x.x.2)	Recommended upgrade
Medium	Minor update (x.1.x → x.2.x)	Test before production
High	Major update (1.x.x → 2.x.x)	Detailed assessment needed

Proxy Configuration for Hangar

If you have proxy issues, configure NO_PROXY:

bash

export NO_PROXY="localhost,127.0.0.1,192.168.8.165,hangar.papermc.io,papermc.io,hangarcdn.papermc.io"

Download URL Pattern

Hangar plugin download URLs follow this pattern:

text

https://hangarcdn.papermc.io/plugins/{plugin}/{plugin}/versions/{version}/PAPER/{plugin}-{version}.jar

Verification Steps After Upgrade

1. Check server logs for errors
2. Verify plugin loaded message
3. Test core functionality
4. Monitor server performance
5. Have rollback plan ready

ViaVersion Upgrade Experience

See viaversion_upgrade_report.json for detailed documentation of the successful ViaVersion 5.7.2 → 5.8.0 upgrade, including:

• Proxy issue resolution
• Risk assessment validation
• Complete upgrade process
• Lessons learned

Health Monitoring

bash

bash scripts/health_check.sh

Checks:

• Service status
• Log errors
• Plugin count
• Backup age
• Disk space
• Memory usage

Version Management Strategy

Balanced Upgrade Strategy

Adopt a balanced approach with 1-version lag for stability.

Weekly Upgrade Scoring System

bash

python3 scripts/weekly-upgrade-scorer.py

Scoring Criteria (100 points total):

1. PaperMC Stability (30 points)

   • Official API confirmation
   • Release age (>2 weeks)
   • Security patches included

2. Plugin Compatibility (40 points)

   • Core plugins compatibility
   • All plugins compatible
   • Recent plugin updates
   • No critical warnings

3. Testing & Validation (20 points)

   • Test environment validation
   • Performance benchmarks
   • Functionality verification

4. Risk Management (10 points)

   • Backup readiness
   • Rollback plan tested

Upgrade Decision Matrix

• ≥ 80 points: Proceed with upgrade (low risk)
• 60-79 points: Further evaluation needed
• < 60 points: Do not upgrade (high risk)

Weekly Scanning Procedure

1. Monday: Run automated scoring
2. Review: Analyze report and scores
3. Decision: Human confirmation required for ≥80 scores
4. Execution: Scheduled upgrade with full backup

Emergency Rollback

Trigger conditions:

• Server crash on startup
• TPS consistently below 15
• Critical plugin failures
• Player data corruption

Rollback steps:

1. Stop server immediately
2. Restore from latest backup
3. Revert to previous version
4. Verify and restart

Safety First

This skill enforces operational discipline:

• All actions through controlled interfaces
• Mandatory backups before changes
• No destructive direct commands
• Full traceability

Never bypass the script layer for "quick fixes."
