Dynamics XRM Tools was initially developed by Rhett Clinton and Ramon Tebar, and is available for both Microsoft Dynamics CRM Online and on-premise Microsoft Dynamics CRM deployments. You download the Dynamics XRM Tools in a .zip file and then import it into Microsoft Dynamics CRM or CRM Online as a Solution. Once you have imported Dynamics XRM Tools, to use them, navigate to Settings > Dynamics XRM Tools > Start (see below). Then access any tool by opening its tab, such as Odata Query Designer, and clicking the relevant button (Designer in this example) to launch the tool.
There is a Dynamics XRM Tools discussion group for those who want to review the product with their peers and provide feedback before the full release.
