What is proxy-network?

Instructions for connecting several Minecraft servers through a proxy such as Velocity, BungeeCord, or Waterfall. A proxy is the front server that sends players to connected servers such as a lobby or game server.

Use it to configure server networks, lobby connections, player switching, proxy addresses, forwarding secrets, and backend server settings.

It prevents mismatched authentication, forwarding, and secret settings that can stop players from connecting or sharing their identity correctly.

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	$0.00155	$0.00846
Opus 5	$0.00077	$0.00423
Sonnet 5	$0.00031	$0.00169
Haiku 4.5	$0.00015	$0.00085

Security

Grade A, and why

proxy-network 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 2d 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.

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.

How it starts

The opening of the file, as written. The whole thing — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Proxy / Network

Default proxy: Velocity (by the Paper team; TOML config, modern forwarding). Waterfall is in maintenance mode; BungeeCord is legacy. See references/velocity-modern-forwarding.md for the exact forwarding handshake — getting it wrong is the #1 network setup failure.

The forwarding contract (must all line up)

For a Velocity network with modern forwarding:

Proxy velocity.toml: player-info-forwarding-mode = "modern" and forwarding-secret-file = "forwarding.secret".
Secret: the proxy's forwarding.secret file contents must exactly equal each backend's paper-global.yml: proxies.velocity.secret.
Backend paper-global.yml: proxies.velocity.enabled: true, matching secret, and proxies.velocity.online-mode equal to the proxy's online-mode.
Backend server.properties: online-mode=false (the proxy handles authentication).
Never also set spigot.yml: settings.bungeecord: true — Velocity + BungeeCord forwarding enabled together stops the backend from starting.

velocity.toml essentials

bind = "0.0.0.0:25565"
online-mode = true
player-info-forwarding-mode = "modern"
forwarding-secret-file = "forwarding.secret"

[servers]
lobby = "127.0.0.1:30066"
survival = "127.0.0.1:30067"
try = ["lobby"]

[forced-hosts]
"play.example.net" = ["lobby"]

[advanced]
compression-threshold = 256
login-ratelimit = 3000

Backends bind to internal/loopback ports; only the proxy port is public. Firewall the backend ports so players can't bypass the proxy (which would hit online-mode=false directly — a security hole).
try sets the initial-connect order; forced-hosts routes by hostname.

Troubleshooting map

Symptom	Cause → fix
"Unable to connect you… invalid forwarding"	secret mismatch or wrong forwarding mode → align secret + set `modern` both sides
Players join as offline UUID / skins broken	backend `online-mode=true`, or `proxies.velocity.online-mode` mismatch → set backend `online-mode=false`, match proxy
Backend won't start	BungeeCord and Velocity forwarding both enabled → disable one
Anyone can join backend directly as op	backend port exposed publicly with `online-mode=false` → firewall to proxy only
Legacy BungeeCord network	use `ip_forward: true` + `bungeecord: true`; do NOT also enable Velocity

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.

proxy-network is a skill published in the GitHub repository Teddy563/mcwrench (1 stars, last pushed 9d ago), licensed MIT. It adds 155 tokens to every session and 846 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
