As far as KC3 goes, it pulls data as it passes through the browser to the Flash application that recieves it (the main game), so unless DMM intentionally added system scanning script to the game, there's no way to find out. Even then your antivirus/firewall wouldn't give access to chrome's cache or your hard disk anyways.

For KCV, I'm not so sure. I've had no issues so far, and all the people that I know use KCV had haven't been banned ever. KCV pulls its info using the FiddlerCore that reads passing data, much like KC3. I think they're a little different, but they essentially do the same thing. Everyone seems to use their favorite version of KCV, I personally use FreyYa's version. Good language support, and translation files are updated often too. If you want you can also use Grabacr's original version as well, not sure it has multilanguage support though (means only Japanese).

The only thing you should be concerned about is your actions. For example, too many refreshes in a certain time period could look suspicious to the server's detection system, which might mean a ban. Or if you execute an action, or even a group of actions, and your timing is too perfect/instantaneous, that might be a sign that you're using a bot or macro, also might mean a ban.

I won't know until I rip the flash apart and look under the hood (even then I believe the detection system is on their servers, not in the actual clients), but tools should be fine. They modify no actual data.

Now CheatEngine is a different story, it actually changes some things to make the flash run faster (or some other thing), which is very noticable when the flash passes data back to the server.
