What is minecraft-modpack-server?

A guide for setting up a server for a modified Minecraft game from a CurseForge or Modrinth server-pack file. It covers installing the required server software, configuring Java, and creating launch, network, and backup settings.

Use it to prepare a modded Minecraft server, tune memory and viewing distances, configure LAN or firewall access, and automate backups and startup.

It helps avoid mismatched Java or server versions and gives the server sensible performance, access, and backup settings.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00048	$0.01869
Opus 5	$0.00024	$0.00934
Sonnet 5	$0.00010	$0.00374

Security

Grade B, and why

minecraft-modpack-server scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

A mod that escalates privileges can change anything on the machine, not only the project.

Minecraft Modpack Server Setup

When to use

User wants to set up a modded Minecraft server from a server pack zip
User needs help with NeoForge/Forge server configuration
User asks about Minecraft server performance tuning or backups

Gather User Preferences First

Before starting setup, ask the user for:

Server name / MOTD — what should it say in the server list?
Seed — specific seed or random?
Difficulty — peaceful / easy / normal / hard?
Gamemode — survival / creative / adventure?
Online mode — true (Mojang auth, legit accounts) or false (LAN/cracked friendly)?
Player count — how many players expected? (affects RAM & view distance tuning)
RAM allocation — or let agent decide based on mod count & available RAM?
View distance / simulation distance — or let agent pick based on player count & hardware?
PvP — on or off?
Whitelist — open server or whitelist only?
Backups — want automated backups? How often?

Use sensible defaults if the user doesn't care, but always ask before generating the config.

Steps

1. Download & Inspect the Pack

mkdir -p ~/minecraft-server
cd ~/minecraft-server
wget -O serverpack.zip "<URL>"
unzip -o serverpack.zip -d server
ls server/

Look for: startserver.sh, installer jar (neoforge/forge), user_jvm_args.txt, mods/ folder. Check the script to determine: mod loader type, version, and required Java version.

2. Install Java

Minecraft 1.21+ → Java 21: sudo apt install openjdk-21-jre-headless
Minecraft 1.18-1.20 → Java 17: sudo apt install openjdk-17-jre-headless
Minecraft 1.16 and below → Java 8: sudo apt install openjdk-8-jre-headless
Verify: java -version

3. Install the Mod Loader

Most server packs include an install script. Use the INSTALL_ONLY env var to install without launching:

cd ~/minecraft-server/server
ATM10_INSTALL_ONLY=true bash startserver.sh
# Or for generic Forge packs:
# java -jar forge-*-installer.jar --installServer

This downloads libraries, patches the server jar, etc.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
