In one word: Yes. SMART AM implements nearly all parts of the UMA protocol. That includes:
- AM Discovery
- Dynamic Host Registration
- OAuth 2.0 flow
- Resource Sets Registration
- Token Status Retrieval
- Host's Permissions Registration
- Requester's Permissions Grant
- OpenID Connect Claims (experimental)
SMART AM provides as well several extensions to the core UMA protocol specification e.g.: Facebook Connect integration and policy set up with user's Facebook friends.
