I don't think that Canon MF Toolbox is compatible with the MG7100 Series scanner/printer primarily because there is no version even mentioned on the Support pages. There is the support page from where you can acquire the drivers to install the software. Once the drivers are installed, you can then proceed to the installation of the Canon MF Toolbox. If you see the device in the software, then you can use it, otherwise it can't be used.
