Modules

What Makes Trouser-Streak Different

No bloated fluff. Every module is tailored for base hunters, griefers, and anarchy players.

NewerNewChunks & Base Hunting

The original palette-based chunk state tracing method. Tells you whether a chunk was previously loaded or generated in older versions by inspecting server packet palettes. Also scans for player trails, chests, and unnatural block placements to make finding stashes faster.

Read Base Hunting Wiki

AutoMountain & Lavacasting

Automates the entire lavacasting process. Builds massive cobblestone mountains and pyramids on auto-pilot without having to manually place lava and water buckets. Also comes with combat tools like SpearKill, MaceKill, and optimized fast-mining.

Help & FAQ

Frequently Asked Questions

What is Trouser-Streak?
Trouser-Streak is a free addon for Meteor Client built by Mountains of Lava Inc. It adds specialized modules for base hunting, automated lavacasting, and server exploits directly into Meteor's existing menu.
Why do I need Fabric API and Meteor Client?
Fabric API provides the essential hooks that Minecraft needs to run Fabric mods, and Meteor Client is the base utility client where Trouser-Streak installs its modules. Without both of these in your mods folder, the game will either fail to launch or Trouser-Streak won't appear.
Can I connect to older servers like 1.12.2 or 1.16?
Yes! Please try ViaFabricPlus. It allows your 1.21 client to connect to older server versions seamlessly, fixing protocol and packet differences so you can use modern tools on older anarchy servers.
How does NewerNewChunks detect bases?
NewerNewChunks reads the block palette data sent across the network by the server. When players visit, load, or modify chunks in older versions, those chunks retain unique packet structure traits that NewerNewChunks flags in real time.
Where can I ask questions or report a bug?
Join the official BreakBlocks Customer Service Discord for community help, feature discussions, and bug reports, or check the Trouser-Streak GitHub Wiki.
