The 2-category of permutative categories. With respect to multi-linear functors (Deligne tensor product) this canonically becomes a multicategory (Elmendorf-Mandell 04, Section 3).
The construction of K-theory spectra of permutative categories constitutes a multifunctor
between multicategories permutative categories (under Deligne tensor product) and spectra (under smash product of spectra).
Hence for a multilinear functor of permutative categories
there is a compatibly induced morphism of K-spectra out of the smash product
This implies that the construction further extends to a 2-functor from the 2-category of enriched categories over the multicategory of permutative categories to that of enriched categories of spectra:
which applies to each hom-object.
