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.

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 | $0.01842 |
| Opus 5 | $0.00010 | $0.00921 |
| Sonnet 5 | $0.00004 | $0.00368 |
| Haiku 4.5 | $0.00002 | $0.00184 |
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 yesterday.
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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

94% identical to minecraft-modpack-server — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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.
