getController().getInterceptorService().getInterceptionStates().getInterceptors()
should get you started. I only have access to an Android device right now so I can’t test it, but those are all in the API docs:
http://apidocs.coldbox.org/cbQuickDocs
If your not registering/unregistering interceptors after the framework loads up, you can probably just look at the config struct:
getController.getSettingStructure()
That was in the API docs too 
The main difference is that the first method should give you access to the actual interceptor objects, even if they’ve changed after startup. The second method should just give you the config struct that existed on startup with the interceptor path.
Thanks!
