What is MC-Headless?
MC-Headless is a powerful Node.js library that simplifies running Minecraft servers (Java, Bedrock, or Cross-play) with a clean, promise-based API. No more dealing with complex Java commands, server.properties files, or manual downloads - just simple JavaScript methods.
Built specifically for developers, sysadmins, and Minecraft enthusiasts who want to automate server management, run headless servers on VPS/Pterodactyl/Termux, or integrate Minecraft servers into their applications.

What's New in 2.2.5
Version 2.2.5 - March 2026
- Plugin Manager System - Auto-download and install popular plugins:
- ProtocolLib
- TCPShield
- Spigot-Optimizers
- Spark (profiler)
- ViewDistanceTweaks
- FarmControl
- EntityDetection
- RAM Disk Technology - Run worlds, plugins, and addons in RAM for lightning-fast performance
- Symlink Master Storage - Secure master folder with symbolic links for data protection
- Auto RAM Backup - Automatically backup RAM data to disk every 5 minutes
- RAM Restore on Crash - Automatically restore data from master storage after crash
- Network Optimization Suite:
- TCP_NODELAY enabled by default
- Adjustable compression threshold (64-512)
- Velocity proxy support
- BungeeCord mode
- Java Arguments Optimization:
-XX:+UseG1GC -XX:MaxGCPauseMillis=50-XX:+UseStringDeduplication-Djava.net.preferIPv4Stack=true-Djava.net.tcpFastOpen=true-Djava.net.tcp.nodelay=true-Dio.netty.recycler.maxCapacity.default=0-Dio.netty.leakDetectionLevel=disabled
- Pterodactyl Port Sharing - Geyser can run on same port as Java when only one port available
- Auto UDP Detection - Warns if Bedrock port needs UDP configuration
- Stream Finished Guarantee - Ensures downloads complete properly with stream.finished
- 1-Second Download Delay - Prevents plugin corruption during simultaneous downloads
- Auto-cleanup Paper Remapped - Automatically removes corrupt
.paper-remappedfolders - Memory Safety - Uses 90% of cgroup limit to prevent OOM killer
- Smart Restart - Only restarts when no players online

node index.jsStep 2: Upload Files via SFTP
# Connect to your server via SFTP and upload:
/home/container/
├── index.js
├── package.json
├── start.sh
└── node_modules/ (will be created by npm install)Step 3: Install Dependencies
cd /home/container

Pterodactyl Memory Safety
The module automatically:
· Detects cgroup memory limits · Uses only 90% of available memory to prevent OOM killer · Adjusts -Xmx accordingly · Logs the adjusted memory value
Port Configuration Options
Option A: Separate Ports (Recommended)
· Add port 25565 (TCP) for Java · Add port 19132 (UDP) for Bedrock · Set both environment variables
Option B: Single Port (Port Sharing)
· Set only SERVER_PORT · Ensure port is configured for BOTH TCP and UDP in panel · Geyser will automatically share the same port · Warning appears if UDP not enabled
How to Connect from Minecraft
Java Edition Connection
- Open Minecraft Java Edition
- Click "Multiplayer" → "Add Server"
- Server Address: your-server-ip:25565 (or your configured port)
- Click "Done" and join
Bedrock Edition Connection
If you have separate Bedrock port (19132 UDP):
- Open Minecraft Bedrock Edition
- Click "Play" → "Servers" → "Add Server"
- Server Address: your-server-ip
- Port: 19132
- Click "Save" and join
If using port sharing (same port as Java):
- Open Minecraft Bedrock Edition
- Click "Play" → "Servers" → "Add Server"
- Server Address: your-server-ip
- Port: 25565 (or your configured port)
- IMPORTANT: Port must have UDP enabled in Pterodactyl panel
- Click "Save" and join
Cross-Play (Java + Bedrock together)
With Geyser and Floodgate enabled, both Java and Bedrock players can join the same server simultaneously. Bedrock players will see Java players and vice versa.

RAM Disk & Symlink System
How RAM Disk Works
When enabled, worlds/plugins/addons are stored in RAM (/dev/shm/minecraft) for lightning-fast access:
ramdisk: {
enabled: true,
world: true, // World in RAM
plugins: true, // Plugins in RAM
addons: true, // Addons in RAM
backupInterval: 300000, // Backup every 5 minutes
masterStorage: '/home/minecraft-master' // Master storage
}Crash Recovery Flow
┌─────────────────────────────────────────────────────────┐
│ CRASH RECOVERY FLOW │
└─────────────────────────────────────────────────────────┘
1. Server crashes or VPS reboots

2. RAM disk data lost (/dev/shm cleared)

4. restoreFromMaster() runs

5. Checks if RAM disk is empty

6. Copies from master storage to RAM

7. World/plugins restored exactly as before

8. Server starts with latest dataBenefits
· 10-50x faster world loading · Zero lag during chunk generation · Instant plugin loading · Automatic backup to disk every 5 minutes · Crash recovery - Data restored from master storage · Data safety - RAM data regularly saved to disk
Symlink Master System
symlinkMaster: '/home/minecraft-master'Creates a secure master folder structure:
/home/minecraft-master/
├── worlds/
├── plugins/
├── addons/
└── mods/Server folders become symbolic links pointing to master folders, providing:
· Data safety - Master data survives server resets · Easy backups - Backup only master folder · Multiple servers - Share plugins across instances · Quick restore - Just recreate symlinks
