The MocServer is an astronomical service dedicated to the manipulation of data set coverages. This server sets together about 15 000 spatial footprints associated to catalogs, data bases and pixel surveys. Thanks to the Multi-Order Coverage map coding method (MOC1.0 IVOA standard), the MocServer is able to provide in a few milliseconds the list of data set identifiers intersecting any polygon on the sky. The MOC server has been deployed in June 2015 by the Centre de Donnees astronomiques de Strasbourg. It is operational and already in use by Aladin Desktop and Aladin Lite prototype versions.
