what exactly do you mean with admin api's?

see http://www.oracle.com/technetwork/java/filters-137243.html
„A filter dynamically intercepts requests and responses to transform or
use the information contained in the requests or responses.” So this Is
something that is part of a web application which is running on tomcat.

I am guessing here: if you want to restrict access to your tomcat server
to certain clients, you could solve this by configuring your firewall
accordingly.
