The record

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.
Search modes: It supports sequential searches over a seed range and randomized searches across the 64-bit seed space.
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.
Performance: Search uses all available logical CPU cores by default and can optionally use CUDA or ROCm/HIP GPU acceleration on Linux x86_64.
Configuration and output: Complex searches can use JSON configuration, and results can be emitted in JSON Lines format for other programs to process.
Build requirements: Building requires Rust and a C11-compatible compiler, and the first build fetches general Rust dependencies from crates.io.
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.
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.
World limits: Searches cover the default world type and do not support large biomes, datapack-modified world generation, or custom dimensions.
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.
GPU behavior: GPU screening is conservative and the CPU path performs final checks of biome, terrain, structure layout, and other world conditions.
License: The repository identifies its license as MIT.
Intended users: The project is for Minecraft Java Edition users who want to find seeds matching specific world-generation conditions.
Search filters: It can filter seeds by spawn biome, nearby biomes and structures, and specific structure pieces.
