Pen Tracker

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

PEN Tracker

A client-side Fabric mod built specifically for The PEN Server — rebuilt from the ground up for Season 3, with rank, prestige and rebirth progression, custom fishing, baking, drugs, sewers and vaults. PEN Tracker sits quietly in the corner of your screen and keeps track of everything that matters. It follows your progress, prices everything you're carrying to the cent, tracks your quests live, and never sends a command on its own.

Only useful on The PEN. Some prices come from an online service — see Data & online service below.

What it does

Progress tracking — your rank, prestige and rebirth are read automatically from the tab list. See the cost of your next rank, every rank left to Z, your next prestige and its token reward, and exactly how far your balance is from it. Prestige and rebirth tokens, cigs and tool power are all on screen too.

Exact sell values — fish, cookies, blocks and drugs are priced the way the server prices them, boosts included. If the server changes a price, your next sale corrects it automatically.

Mining overlay — see the sell value of everything in your inventory at Commissary prices, plus what's sitting in your vaults and backpack.

Money tracking — a rolling hourly total from every kind of sale: the sellall trader, AutoSell, fish, cookies, sewer kills and Auction House sales, plus cigs/hr from drug sales.

Fishing mode — counts and values the fish in your inventory, vaults and backpack, flags fish that aren't yours, and shows keys earned this session.

Cookie mode — tracks Baking Wheat, Baking Cocoa, Cookies and Super Cookies, shows how many batches you can make, and prices them for your hoe and progression.

Drug lab — shows the drugs you're holding and their value in cigs (raw and processed), your level on every lab upgrade with the next cost, and the cheapest upgrade to buy next.

Sewers — kills and money per hour while you grind, and exactly what the server pays per kill.

Quests — every NPC's quest, your progress and the reward. Run /quests once and it updates live as you bake, fish, mine, process drugs, chop, duel, level mcMMO, sit in the AFK room or carry hand-in items.

Vault & backpack browser — press V to open a full-size preview of all your vaults (or your backpack pages) 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. Contents are cached to disk and survive relogs. Bare /v and /bp reopen the last one you used.

PEN Tracker users in tab — players using PEN Tracker show with a gold name and ⛏ in your tab list while they're playing with it. You can opt out any time.

Vote opener — typing /vote opens all the voting sites in your browser with a short stagger between tabs.

Chat filtering — optional toggles to hide fish sell confirmations, vault open/close messages and server restriction messages, plus a Discord ignore list for relayed messages (staff can't be ignored).

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

Data & online service

Some prices (fish, cookies, sewer pay and prestige costs) come from the PEN Tracker price service instead of being built into the mod. To use it, the mod signs in with your Minecraft account's chat-signing key — no password is ever sent. It sends:

• your Minecraft UUID
• the fish it needs priced (species and size)
• what your cookie and sewer prices depend on: rebirth, prestige, tool power, hoe enchants, mining and rebirth upgrades, and active money boost
• when you join and leave, so other PEN Tracker users can see the gold tab marker (turn off Show Me In Tab to opt out)

Nothing else is collected, and nothing is shared with anyone. If the service can't be reached, the mod keeps working with whatever it can still price.

Built for The PEN

Every price, every formula, every chat pattern is tuned specifically to The PEN's Season 3 economy. This isn't a general-purpose prison mod — it's built around one server and does that one job well.
