CDSEO doesn't generate urls 'on the fly' but there's an auto-populate feature which will populate all empty fields with the click of a button. We also have an admin addon that can be used enter the SEO information at the time of items.

Be default it wouldn't generate a manufacturer-product-keyword url format. Those could be entered in manually.

You could customize your items to auto-populate when added, and customize your url format, though the 'keyword' portion of the url would be difficult to populate unless you had a general keyword to insert.
