Merchant Master Key Wiki & Guide

Right-click any trading villager to open their trade window—you'll see the mod's overlay with new options. From there, you can preview locked trades, inspect the villager, or set up an auto-reroll search if you're looking for a specific enchantment.

Locked trades are future offers that appear only after you level up a villager by trading with them. The preview shows you what those hidden trades will be before you spend emeralds, so you can decide if it's worth leveling them up or if you should reroll instead.

Empty-hand right-click (or Shift-right-click) a non-trading villager to pick them up as an item in your inventory. All their trade data, progress, and breeding status are saved—just place them down wherever you want in your trading hall.

Yes—open the Trade Condition Editor, set your target enchantment and tier level, then start the auto-reroll. The mod will cycle through the villager's trades automatically until it finds a match, and it saves the best offer it finds so you can roll back to it anytime.

A villager loses their job if they can't reach their workstation block or if the block is destroyed. Use the Villager Inspector to diagnose the issue—it will tell you whether the workstation is missing or unreachable. Replace or reposition the job block so the villager can access it, and they'll restock their trades.

Empty-hand right-click the villager to open the Inspector window, which displays their exact breeding cooldown timer in seconds and shows whether they have enough food and willingness. It also prevents them from wandering while you're checking their stats.

Yes—use the Village Trade Browser to scan all nearby villagers within a chosen radius and list every active trade offer in one screen. You can filter by item type or enchantment to find exactly what you need without walking house to house.

Manual cycling lets you browse each trade one at a time, while auto-reroll continuously cycles through trades and scores them automatically, replacing weaker offers with better ones. Auto-reroll is much faster for finding specific enchantments, but you can always roll back to any saved offer.

Yes—the Trade Condition Editor lets you save, rename, and export your custom search profiles. You can also clone an existing villager's trade directly into a filter with one click, then apply that same profile to other villagers to find matching offers.
