Show HN: Agentic Identity Broker, OAuth Delegation for AI Agents (github.com)

The Agentic Identity Broker, a new project from Zalando Engineering, has been announced to streamline OAuth2 delegation for AI agents. This innovative tool manages delegation chains for "on-behalf-of" flows, simplifying the interaction between various services like Google and GitHub without compromising user control over permissions. By deploying the broker alongside gateways such as Agentgateway, it offloads authentication tasks from both agent developers and Managed Control Plane (MCP) server creators, utilizing a secure token vault for efficient permission management. This development is significant for the AI/ML community as it enhances security and user experience in agent interactions with multiple MCP servers through centralized token management. The broker allows agents to operate with a single user token across various services, thus reducing complexity for developers. With features like sensitive value redaction and audit logging, it reinforces security and compliance standards. The roadmap also includes future enhancements focusing on intent-based authorization and user-facing activity logs, indicating a strong commitment to evolving agentic engineering practices in a structured, open-source manner.
