PEN Tracker

A client-side Fabric mod built specifically for The PEN Server — a Minecraft prison server with prestige progression, custom fishing, baking, and vault systems.

PEN Tracker sits quietly in the corner of your screen and keeps track of everything that matters. It monitors your economy, tracks your progression, protects your active sessions from interference, and automates the small things so you can focus on playing.

What it does

Prestige tracking — always know exactly how much money and how many shards stand between you and your next prestige. Auto-detects when you prestige up and saves your new level instantly.

Mining overlay — scan your inventory in real time and see the total sell value of everything you're carrying, broken down by item with prestige comm % applied.

Shard tracking — silently polls your shard balance every 10 seconds and shows a live shards/hr rate and rolling hourly earned total without cluttering your chat.

Money tracking — listens for sell messages from AutoSell, Commissary, Shop, and the Fish Merchant, and shows a rolling hourly total of everything you've earned this session.

Fishing mode — tracks key drops as they arrive, reads your /key menu balance and keeps it accurate, flags fish that won't sell at your current prestige tier, and estimates the sell value of fish in your inventory.

Cookie mode — scans your inventory for Baking Wheat, Baking Cocoa, Cookies and Super Cookies, shows how many batches you can make, and calculates sell value using the correct Green Thumb or standard formula automatically.

Vault browser — press V to open a full-size preview of all your vaults without sending a single command. Browse freely, hover to inspect items, and use the pencil to open one on the server when you're ready. Vault contents are cached to disk and survive relogs. The mod also intercepts bare /v and /vault commands and redirects them to your last opened vault.

AFK management — automatically sends /afk after 10 minutes of inactivity and suspends all polling so no background commands pull you out of AFK mode. Resumes cleanly when you return.

Session protection — polling is automatically suspended during active trades, while in MobArena, and resumes the moment the session ends. No more trades being aborted by background commands.

Keys lock — optionally block access to /keys and /key below a configurable prestige threshold, with a clear in-chat message explaining the lock when triggered.

Vote opener — typing /vote automatically opens all six voting URLs in your default browser with a short stagger between tabs.

Chat filtering — optional toggles to suppress /bal responses, shard balance messages, key delivery and withdrawal notices, fish sell confirmations, mining notifications, vault open/close messages, vote popups, and server restriction messages.

Keybinds — assign keys to /d, /condense, /arm gui, /prestige, /bake, /minetop, and AH sell. All unbound by default and visible in both the Controls screen and the ModMenu settings panel.

Built for The PEN

Every formula, every prestige multiplier, every chat pattern is tuned specifically to The PEN's economy. This isn't a general-purpose prison mod — it's built around one server and does that one job well.

Requires Fabric 1.21.10 — Client-side only
