MCRPX is a client-side web application to extract files from Minecraft: Java Edition resource packs. It can also bypass corrupted resource packs, used by servers to protect their resource packs.You can find the web application here or you can use it locally.
Minecraft resource pack protection typically functions by intentionally corrupting file headers, checksums, and other metadata. This tool bypasses these integrity checks to generate repaired, fully extractable ZIP archives with restored internal content.
