Auction Tracker
If you spend any time trading on multiplayer Minecraft servers, you know the pain of guessing prices. You open an auction house, see a dozen listings, and have no idea if you are overpaying or underselling. The Auction Tracker add-on solves this completely. It watches every container and menu you open, records the prices you see, and then displays that data right in your tooltips when you hover over items. No more alt-tabbing to a spreadsheet. No more relying on memory. This mod turns your client into a personal market analyst.
What Makes Auction Tracker Stand Out?
This is not just a simple price logger. The v1.2 update brought a complete overhaul of how the mod works under the hood. The new Silent Scanning Engine is the star of the show. Previously, you had to type a command like /at scan to force the mod to look at prices. Now, the engine passively records prices from any container or menu you open. You just play the game normally, and the data builds itself. This is a massive quality-of-life improvement for anyone who wants to keep trading without interrupting their gameplay.
Context-Aware Tooltips and Smart Blocking
The tooltip system has been rewritten from the ground up. The mod now understands exactly where you are looking. If you are browsing an auction GUI, it will show price info on the items for sale. If you are in a mixed-purpose screen, like a server menu that also shows your inventory, the mod performs an Ownership Check. Tooltips only appear for items that actually belong to you. This cuts down on visual clutter significantly.
Furthermore, Smart Blocking suppresses tooltips on navigation buttons like Back, Next, or Refresh. It also ignores system items such as Game Selectors, Pets, and Daily Rewards. This means you only see relevant data, not noise.
Data Freshness and Stack Awareness
One of the most useful additions is the color-coded "Last Scanned" status. If the data is less than one hour old, the tooltip shows a green indicator. If the data is stale or needs a fresh scan this session, it turns red. You instantly know if you can trust the price you are looking at.
The mod is also Stack-Size Aware. If you hover over a stack of items, say 64 cobblestone, the tooltip calculates the total value for the entire stack, not just a single unit. This applies to both the Lowest and Highest seen prices. It saves you from doing mental math every time you list something for sale.
Precision Parsing and Compact Dates
Different servers use different currency formats. Some use $1,500.00, others use $1.500,00. The upgraded regex engine handles both, along with other complex separators. This ensures the prices are parsed correctly every time. Additionally, dates are automatically shortened. Instead of showing "2026", the tooltip shows "26". This keeps the tooltip narrow and readable, even on smaller GUI scales.
Installation and Compatibility
Wondering how to install this mod? The process is straightforward. Auction Tracker for Minecraft is built for Fabric 1.21.x. You will need to have Fabric Loader and Fabric API installed on your client. Once you have those, simply drop the mod JAR file into your mods folder and launch the game.
The latest update specifically updated entrypoints and mixins to support the newest DataComponentTypes and DrawContext standards. There is also a Fail-Safe Registration system for keybindings. This uses a try-catch wrapper to prevent client crashes if you have a mismatched version of Fabric API installed. This makes the mod much more stable for users who play on modpacks with varying dependency versions.
New Input Options and Quick Menu
In addition to passive scanning, you can still trigger scans manually. A dedicated hardware hotkey has been added, defaulting to the J key. Pressing it instantly triggers a scan of the currently open screen. This is perfect for when you want to force a refresh on a specific auction page.
There is also a brand-new Quick-Menu, called AuctionUIScreen. This is a central GUI that lets you toggle the scanner on and off, and view your entire price history, all without typing a single chat command. It is a much cleaner way to manage the mod.
Data Export and Internal Optimizations
For players who like to analyze trends, the XLSX Export feature is now fully functional. The background ZIP and XML compression logic has been completed. You can export your entire auction history to a spreadsheet file for deeper analysis outside the game. The mod also uses a new Fingerprint System for item identification. It combines the Namespace and DisplayName, so custom-named items are tracked separately from their generic counterparts. This prevents data mixing.
Finally, the tooltip cleaning process has been improved. It aggressively removes duplicate "Lowest Price" lines that might be generated by other server-side mods. This keeps your tooltips clean and free of redundant information. If you are looking for a way to get an edge in the market, you should download Auction Tracker today and start recording your server's economy.
If you want a hassle-free setup, consider using the foxygame.net launcher. Its add-on catalog includes Auction Tracker, allowing you to install it with a single click. The launcher also handles version compatibility checks automatically, ensuring you always run the right build for your Minecraft version, and it can auto-update the mod when new releases drop.
Final Thoughts on Auction Tracker v1.2
The v1.2 update removes legacy 1.1 scanning methods that caused GUI flickering. It also deprecates the old manual reference system in favor of the new 1.2 Standard. This is a clean break from the past, focusing entirely on stability and performance. The silent scanning engine, context-aware tooltips, and robust export options make this an essential tool for any serious trader. Whether you are flipping items for profit or just trying to avoid getting scammed, this mod gives you the data you need right where you need it. Install it, scan your server, and start making smarter trades immediately.
