Best For
Multi-tenant SaaS, token delegation for agents, fine-grained authorization at scale
Enterprise SSO, M2M authentication, and fine-grained authorization for B2B agent products
Limitations
Vendor lock-in on cloud plan; self-hosted (Private Cloud) is enterprise-tier only; dynamic client registration for MCP requires Enterprise plan to secure against abuse
No dedicated agent SDK; FGA is strong but relatively new; async authz patterns require custom integration
