Does SEOmoz have a tool to find mirror sites?

I heard from a company that is trying to get my clients SEO business that they discovered multiple sites mirroring our site's content. Does SEOmoz have a tool to find these websites? Or does Google?

I would use Google to do a search for the content to see what comes up. Also Google gives all the credit to the first content indexed. So you will not be punished as long as your content was indexed before the syndications.
