MTClient runs on the client PC as an applet, browser plugin or standalone Java application. It manages screen mapping, the population of data forms and the flow of data between itself and MTDynamo. It also has rich data validation capabilities and can be extended to include bespoke modules that perform more extensive processing.

Most end-users will run MTClient on a Windows PC, however, it will function just as effectively in other client environments including advanced set-top boxes and Linux.

Mart Technology has injected a substantial amount of resources into the research and development of MTClient to provide a reliable and comprehensive product that can compensate for the web browser's inherent deficiencies as a graphical user interface (GUI).
