MineTracer

MineTracer is a powerful and lightweight block, container, sign, and kill logging mod for Minecraft servers, designed to help server administrators monitor, investigate, and roll back player actions with ease. Built for Fabric, MineTracer provides advanced logging and rollback capabilities while remaining simple to use and highly configurable.

This mod is still under developement so don't expect everything to work flawlessly. Please write an issue report on GitHub if you find a bug, I am happy to recieve feedback!

• Block Logging Tracks all block break and placement events, including full NBT data for accurate restoration. Supports all block types, including those with complex states or tile entities.

• Container Logging Monitors interactions with chests, furnaces, hoppers, shulker boxes, and other containers. Logs both item withdrawals and deposits, including item counts and types.

• Item Pickup/Drop Logging Track when players pick up or drop items

• Sign Editing Records all sign text changes, storing both the previous and new text for each edit, allowing for easy investigation and restoration.

• Kill Logging Logs all player and mob kills, including killer and victim names, locations, and timestamps.

• Advanced Query System Search logs using flexible filters such as player name, time range, radius, action type, and specific item or block IDs. Combine multiple filters for precise lookups.

• Rollback Functionality Instantly undo player actions within a specified area, time frame, or by specific users. Rollbacks are safe and only affect the filtered actions, minimizing risk of unwanted changes.

• Inspector Mode Toggle inspector mode to view block history in real time. Right-click or break blocks to see a detailed log of recent actions at that location.

• Permission-Based Access All commands and features are protected by permissions, allowing fine-grained control over who can view logs, perform rollbacks, or use inspector mode.
