Resolve a fresh no-account itch.io download page and list its upload IDs, names, sizes, license, and safe suggested filenames. Signed page tokens are never returned.

Resolve a fresh signed itch.io file URL for a listed upload and stream it into guarded local storage after explicit license acknowledgement. Signed URLs are not exposed in the MCP result.

Range-extract and cache only the aggregate GLB from a curated bundle, then return its named animation clips. The standard non-root-motion GLB is selected automatically when entryPath is omitted.
