We will present the science goals of the SVOM mission and how the Microchannel X-ray Telescope (MXT) will contribute to reach them. SVOM a a Sino-French mission (to be launched by the end of 2021) dedicated to Gamma-Ray Bursts and transient sky studies, and MXT is part of the payload that will be delivered by France. It is a focussing soft X-ray (0,3-6 keV) telescope, which is based on a new optical concept called "Lobster-Eye", coupled to a low noise pn CCD detector. The Irfu/DAp carries the scientific responsibility of the entire telescope, and is in charge of the development of the camera, including all the functions around the detector to get optimal performance. We will present the design of the camera, the associated challenges and the recent achievements.
