minecraft-modpack-server

minecraft-modpack-server is a skill for Claude Code, Codex from graniet/kheish. It costs 43 tokens per session (1,999 once invoked), scanned B, a copy of minecraft-modpack-server, Apache-2.0.

A setup guide for running a server for a modded Minecraft game using a CurseForge or Modrinth server-pack ZIP file. It covers NeoForge and Forge, the systems that load Minecraft mods.

In plain words
What is it for?
Installing the server, choosing the Java version, tuning memory settings, configuring firewalls and LAN access, creating backups, and preparing launch scripts.
Why use it?
It brings together the installation and configuration work needed to make a modpack server run reliably. It also addresses performance, network access, and recovery if server data is lost.

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.

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 4d 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 1.21+ → Java 21: `sudo apt install openjdk-21-jre-headless`

How it starts

The opening of the file, as written. The whole thing — 207 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Kheish Compatibility

This skill is repo-local and stays inactive until explicitly activated.

When the original instructions refer to legacy tool names, use these Kheish mappings:

  • terminal => bash
  • web_extract => web_fetch, plus web_search when discovery is needed
  • search_files => grep_search and glob_search
  • browser_* tools require a browser-capable surfaced tool or MCP; if none is available, use the closest available surface and say so explicitly

When the instructions mention local helper files, resolve them from ${KHEISH_SKILL_DIR}.

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.

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.
