  Langlands has described the irreducible admissible representations of $T$,
when $T$ is the group of points of an algebraic torus over a local field. Also,
Langlands described the automorphic representations of $T_{\mathbb A}$ when
$T_{\mathbb A}$ is the group of adelic points of an algebraic torus over a
global field $F$.
  We describe irreducible (in the local setting) and automorphic (in the global
setting) $\epsilon$-genuine representations for covers of tori, also known as
metaplectic tori, which arise from a framework of Brylinski and Deligne. In
particular, our results include a description of spherical Hecke algebras in
the local unramified setting, and a global multiplicity estimate for
automorphic representations of covers of split tori. For automorphic
representations of covers of split tori, we prove a multiplicity-one theorem.
