Defining agents versus users

In this episode of the Identity at the Center Podcast, hosts Jeff and Jim sit down with Tobin South, co-chair of the OpenID Foundation's AI Identity Management Community Group, to delve into the intricacies of identity management in the age of agentic AI. They discuss the challenges and solutions related to AI agents, the role of the Model Context Protocol (MCP), and the concept of recursive delegation and scope attenuation. Additionally, the conversation covers practical advice for developers and enterprises on preparing for AI-driven identity management and explores the cultural touchstone of coffee from various global perspectives.
