General Settings

General Settings contains per-server configuration that can be changed at any time — not just during creation.

Basic Options

Setting	Description
Server Name	Display name shown in the MC-Vector sidebar
Software	Server type: Vanilla, Paper, Spigot, Fabric, or Forge
Version	Minecraft version (e.g., 1.21.1)
Port	TCP port the server listens on (default: 25565)
Memory	JVM heap allocation in MB (e.g., 4096 for 4 GB)

Java Version

Select the Java runtime for this server:

• System Default — uses the Java installation found on $PATH
• Custom — choose a specific binary managed by MC-Vector’s Java Manager

Java Manager

Click “Manage Java” to open the Java Manager, which lets you download and manage Java runtimes:

Java Version	Use for
Java 8	Minecraft ≤ 1.16
Java 17	Minecraft 1.17–1.20
Java 21	Minecraft 1.21+

To download a version, click “Download” next to it. Progress is shown in real-time. The binary is extracted automatically.

JVM Extra Arguments

Add custom JVM flags in the JVM Extra Args field. Flags are validated before saving.

Common examples:

-XX:+UseG1GC -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=200

Auto-Restart

When enabled, MC-Vector automatically restarts the server if it crashes:

Setting	Description
Auto-Restart on Crash	Enable/disable automatic restart
Max Restarts	Maximum restart attempts before giving up
Restart Delay	Seconds to wait between crash detection and restart

Automatic Backups

Configure scheduled backups for this server:

Option	Description
Schedule type	Interval (every N minutes), Daily (HH:MM), or Weekly (day + HH:MM)
Retention by count	Keep only the N most recent backups
Retention by age	Delete backups older than N days

Notifications

MC-Vector can send OS-level notifications for server events:

• Crash — when the server crashes
• Start — when the server comes online
• High CPU — when CPU usage exceeds a configurable threshold

Ngrok Integration (Port Forwarding Elimination)

Enable Port Forwarding Elimination to open a public TCP tunnel so friends can connect without router configuration.

1. Enable the toggle.
2. Enter your Ngrok authtoken.
3. MC-Vector downloads the Ngrok binary if needed.
4. A public address is generated (e.g., tcp://0.tcp.ngrok.io:XXXXX).
5. Share 0.tcp.ngrok.io XXXXX with players — they enter it as the server address in Minecraft.

Note

A free Ngrok account provides one simultaneous tunnel. The public address changes each time Ngrok restarts.

See the Ngrok page for detailed setup instructions.
