Interesting approach. Where I work, we use Jenkins for collecting results. That way, for each build of our application we have a history of results for static analysis. Jenkins has good tools for storing and displaying this information, as well as the ability to show trends over time.
If Jenkins works for you, great. It does seem to support both clang and cppcheck, although not PVS-Studio (which is one of the better tools out there in my experience).
Personally, I'm happier with plain old text files that can be manipulated with awk, grep, etc., can be databased if needed (since they're csv files) -- and can also be compared using my all-time favorite software, Beyond Compare.
