Collection Notes

Cisco Duo describes an infrastructure-agnostic authorization layer for AI agents across AgentGateway, AWS Bedrock AgentCore, Arcade, Cisco Secure Access, and Envoy.
The proposed control model combines agent discovery, first-class non-human identity lifecycle, accountable human ownership, and least-privilege authorization at every tool call.
Each tool call can produce an identity-correlated audit chain shaped as human -> agent -> tool -> action.
The article presents OAuth 2.1 and OIDC-based integration with MCP clients and emerging agent protocols.

Signals that agent authorization is moving from gateway-level connectivity to per-tool-call policy decisions.
Relevant to general MAS identity propagation, delegated authority, and cross-gateway policy consistency.
