Hi Hamdy,
You may want to go through the below link to understand the MIC card and the services offered;
http://www.juniper.net/documentation/en_US/junos15.1/topics/concept/ms-mic-and-mpc-overview.html
I could only see the below two features needing license on the MIC card;
Link Services Software License—up to 64 ML bundles per Chassis for AS PIC, MS PIC and MS DPC
License to run one instance of the NAT software on one NPU per MS-MIC, MS-DPC, or MS-MPC
To check further you can refer to the below link for all the features that need licensing;

Hope this helps!
