What is minecraft-modpack-server?

A setup workflow for hosting a Minecraft server that runs modpacks from CurseForge or Modrinth. It covers server-pack installation and configuration for Forge or NeoForge.

Use it to configure a server name, seed, difficulty, game mode, player limit, RAM, view distance, PvP, whitelist, and backup settings, then tune the server.

It helps turn a modpack archive into a configured multiplayer server and guides choices that affect gameplay, performance, access, and backups.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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	$0.00019	$0.01851
Opus 5	$0.00010	$0.00925
Sonnet 5	$0.00004	$0.00370
Haiku 4.5	$0.00002	$0.00185

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.

Asks for rootmediumPrivilege escalation

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.
