  We describe the C*-algebra generated by an irreducible Toeplitz operator
$T_{\psi}$, with continuous symbol $\psi $ on the unit circle $\mathbb{T}$, and
finitely many composition operators on the Hardy space $H^2$ induced by certain
linear-fractional self-maps of the unit disc, modulo the ideal of compact
operators $K(H^2)$. For composition operators with automorphism symbols, we
show that this algebra is not isomorphic to the one generated by the shift and
composition operators.
