mrpack-utils

Utilities for working with Modrinth-format (mrpack) Minecraft modpacks.

All commands are read-only.

List modpack contents

uv run mrpack list mods.mrpack

Check for compatibility with newer game versions

Modpacks can only be upgraded to a newer game version if every mod in the pack supports that version. For each mod in the modpack, the script checks whether a version of the mod exists that is compatible with the given game versions, and reports which mods are not compatible:

uv run mrpack list --check-version 1.20 --check-version 1.20.1 mods.mrpack

Limitations:

• Only supports Modrinth modpacks (mrpack), and only checks mods from Modrinth. CurseForge mods in the 'overrides' section of the modpack will have to be checked manually.
• Doesn't actually update the modpack to the newer game version, only reports whether the update would be possible. Mod loaders can do the update.

Diff modpack versions

uv run mrpack diff v1.mrpack v2.mrpack
