How to prepare a list of domain for Content-security-policy?

Going to prepare a list of domains for Content-security-policy, I'd like if it's possible to use a scanner with the following features:

• the scanner should find and analyze all existing pages either using sitemap or by following links (found on pages)
• the scanner should find and list all domains which are used to load remote media such as images, scripts, css, fonts, etc with mime types of such media (which is loaded from a domain from the list).

Anybody here knows such a scanner? It would be great if you share a link to it.

Regards, Alex.
