  The Microchannel X-ray Telescope (MXT) will be the first focusing X-ray
telescope based on a "Lobster-Eye" optical design to be flown on Sino-French
mission SVOM. SVOM will be dedicated to the study of Gamma-Ray Bursts and more
generally time-domain astrophysics. The MXT telescope is a compact (focal
length ~ 1.15 m) and light (< 42 kg) instrument, sensitive in the 0.2--10 keV
energy range. It is composed of an optical system, based on micro-pore optics
(MPOs) of 40 micron pore size, coupled to a low-noise pnCDD X-ray detector. In
this paper we describe the expected scientific performance of the MXT
telescope, based on the End-to-End calibration campaign performed in fall 2021,
before the integration of the SVOM payload on the satellite.
