new-server-bootstrap

new-server-bootstrap is a skill for Claude Code, Codex from Teddy563/mcwrench. It costs 170 tokens per session (1,197 once invoked), scanned A, original, MIT.

Instructions for creating a new Minecraft server using Paper, a Minecraft server software project, with optional Velocity proxy support for connecting multiple servers. It covers the initial installation and configuration.

In plain words
What is it for?
Use it to choose a single server or network, download the correct Paper build, install Java, complete the first run, and prepare the server for game modes.
Why use it?
It turns a blank machine into a working server base and identifies the Java version and setup steps required by current Minecraft server software.

Skill for Claude CodeCodex

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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 A, and why

new-server-bootstrap scanned grade A with 0 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 5d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/fetch-paper.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

New Server Bootstrap

Stand up a working base server, then layer the gamemode stack on top.

Current facts (verified 2026-06-07): Minecraft is 26.1.x. Latest Paper is 26.1.2 build 69. Paper 26.1+ requires Java 25. Velocity is 3.5.0-SNAPSHOT (needs Java 21+). Always re-query the API for the live latest build at setup time.

Steps

  1. Scope. Single server or a network? Gamemode? Host (self-hosted, Pterodactyl/Pelican, other)? Player count? → recommend Paper by default (see Folia note below).
  2. Download the latest Paper build — use the Fill v3 API (the old v2 API stopped builds 2025-12-31). Do NOT hand-construct download URLs; read the URL from the API response. Helper: 
    node "${CLAUDE_PLUGIN_ROOT}/skills/new-server-bootstrap/scripts/fetch-paper.mjs" 26.1.2
#   prints the resolved STABLE build + download URL (and --download to fetch it)
    Manually: GET https://fill.papermc.io/v3/projects/paper/versions/{MC}/builds, pick the newest channel: STABLE, download downloads."server:default".url. A descriptive User-Agent is required by the API.
  3. Install Java 25 (Paper 26.1+ will not start on older Java). Verify java -version.
  4. EULA + first run. Run once: java -jar paper.jar --nogui → it writes eula.txt and stops. Set eula=true (or pass -Dcom.mojang.eula.agree=true). Restart → it generates server.properties + the world and comes online.
  5. Startup script. Use the template assets/startup.sh.tmpl (Java 25 + Aikar's/G1 flags + --nogui). Keep Xms == Xmx with host headroom (leave ~1–1.5 GB; on a panel keep Xmx below the container limit — see pterodactyl-ops). Aikar's flags are PaperMC's documented default; only consider Generational ZGC as a Java-25 alternative, never mixed.
  6. server.properties starter values — see assets/the table below. Set online-mode, view-distance, simulation-distance, max-players, motd, difficulty, gamemode.
  7. Network? If multiple servers, set up Velocity (assets/velocity.example.toml): first run generates velocity.toml + forwarding.secret; set player-info-forwarding-mode = "modern", put the secret into each backend's paper-global.yml (assets/paper-global.example.yml), set each backend online-mode=false, and firewall backend ports. Full detail: proxy-network.
  8. Gamemode stack → hand off to gamemode-stacks for the archetype's plugins.
  9. Review → run audit-config on the finished tree; tune with performance-tuning.

Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
