Core Features

Modpacks & Loaders

Supported mod loaders, Modrinth and CurseForge archive imports, and missing-file completion.

mcl separates ordinary instance loader selection from modpack-pinned environments while sharing the same underlying installation and verification pipeline.

Supported loaders

  • Vanilla
  • Fabric
  • Quilt
  • Forge (legacy 1.7.10 / 1.12.2 and modern client processors)
  • NeoForge

For verified Windows version coverage and known network boundaries, see Windows Compatibility.

Importing modpacks

You can import .mrpack (Modrinth) and .zip (CurseForge manifest) archives either from the Market or from a local file on disk:

  1. mcl inspects the archive, verifies hashes/boundaries, and shows optional files for selection.
  2. Files are downloaded or matched into the digest cache before client overrides are applied.
  3. If a CurseForge mod restricts third-party distribution, mcl lets you select the manually downloaded archive from your computer, verifies its exact size and hash, and resumes the same staging pipeline.
  4. Imported modpacks also expose an instance-level Repair / Missing Files flow to restore missing pinned files or client overrides.
