Is there a tool or a way to reboot router from Dude?
Yes, it is possible. Device should be with ‘login and password’.
Open ‘Devices’ —> double click on the device you want to reboot —> Reboot
Yes, I knew that 
Maybe I wasn’t clear with question. I need a tool for that. I have a lots of routers so it’s boring to open each one. It would be a good if I can do it from u right click popup (tool or directly) or maybe from Devices/RouterOS-separate or gorup.
maybe you can make a new tool that executes “plink” (a putty relative) and runs the reboot command ?
