Facts

Purpose
MCSeed Finder is a command-line seed filter for Minecraft Java Edition 26.2 that searches for worlds matching biome, structure, and structure-piece conditions.github.com · 8 Oct 2026
Search modes
It supports sequential searches over a seed range and randomized searches across the 64-bit seed space.github.com · 8 Oct 2026
Search features
Conditions can include spawn and nearby biomes, structures, structure pieces, and the number of eyes initially present in the nearest stronghold portal frame.github.com · 8 Oct 2026
Performance
Search uses all available logical CPU cores by default and can optionally use CUDA or ROCm/HIP GPU acceleration on Linux x86_64.github.com · 8 Oct 2026
Configuration and output
Complex searches can use JSON configuration, and results can be emitted in JSON Lines format for other programs to process.github.com · 8 Oct 2026
Build requirements
Building requires Rust and a C11-compatible compiler, and the first build fetches general Rust dependencies from crates.io.github.com · 8 Oct 2026
Local operation
The world-generation implementation is included in the repository, and build, run, and test do not read Minecraft JARs or game installation files.github.com · 8 Oct 2026
Accuracy limits
The tool does not generate complete block chunks, so some spawn landing blocks and some approximate terrain checks may differ from the game.github.com · 8 Oct 2026
World limits
Searches cover the default world type and do not support large biomes, datapack-modified world generation, or custom dimensions.github.com · 8 Oct 2026
Structure-piece limits
Some structures have partial piece coverage, while mineshafts, mansions, ocean monuments, ocean ruins, ancient cities, trail ruins, trial chambers, and nether fossils support parent-structure searches only.github.com · 8 Oct 2026
GPU behavior
GPU screening is conservative and the CPU path performs final checks of biome, terrain, structure layout, and other world conditions.github.com · 8 Oct 2026
License
The repository identifies its license as MIT.github.com · 8 Oct 2026
Intended users
The project is for Minecraft Java Edition users who want to find seeds matching specific world-generation conditions.github.com · 8 Oct 2026
Search filters
It can filter seeds by spawn biome, nearby biomes and structures, and specific structure pieces.github.com · 8 Oct 2026
Parallel search
Search defaults to using all logical CPUs reported by the system, and users can set the thread count.github.com · 8 Oct 2026
Random search
Random mode traverses the signed 64-bit seed space in a pseudorandom permutation without repeating seeds.github.com · 8 Oct 2026
GPU acceleration
On Linux x86_64, users can build CUDA or ROCm/HIP variants; the default build does not require a GPU SDK.github.com · 8 Oct 2026
Game files
The repository says its build, runtime, and tests do not read Minecraft JARs or game installation files, and it does not download game files during build or runtime.github.com · 8 Oct 2026
World compatibility
Searches cover the default world type and do not support large biomes, data-pack-modified world generation, or custom dimensions.github.com · 8 Oct 2026
Partial piece searches
Pillager outposts currently expose only watchtowers and bastion remnants expose four implemented required pieces; several other structures support parent-structure searches only.github.com · 8 Oct 2026
Suggested verification
The README recommends confirming found seeds in Minecraft 26.2 before long-term use.github.com · 8 Oct 2026
