The DataONE 'node' service requests a member node to provide a list of service packages that it supports, for example https://knb.ecoinformatics.org/knb/d1/mn/v2/node
will list the implemented packages:
...
<services>
<service name="MNCore" version="v1" available="true"/>
<service name="MNCore" version="v2" available="true"/>
<service name="MNRead" version="v1" available="true"/>
<service name="MNRead" version="v2" available="true"/>
<service name="MNAuthorization" version="v1" available="true"/>
<service name="MNAuthorization" version="v2" available="true"/>
<service name="MNStorage" version="v1" available="true"/>
<service name="MNStorage" version="v2" available="true"/>
<service name="MNReplication" version="v1" available="true"/>
<service name="MNReplication" version="v2" available="true"/>
</services>
...

However, it appears that not all service packages are being reported, as KNB supports the 'getPackage' service that is part of "MNPackage", which does not appear.
Also, "MNView" and "MNQuery" do not appear.

The full list of course, is here: https://purl.dataone.org/architecture-dev/apis/MN_APIs.html
