You don’t have to install all of the full SQL Server client tools to get connectivity to SQL Server or analysis services.  They have been broken up and are available individually for download as part of the SQL Server feature pack.

There’s also a load of other utilities like backward compatibility stuff e.g. to edit and run data transformation services packages.

Finally as I have blogged before these tools are not licensed in themselves, it is SQL Server that is licensed for either client access or per cpu (socket NOT core).
