The Identity Layer Is What's Holding Browser Agents Back: Catherine Jue (Kernel)

Catherine Jue, co-founder and CEO of Kernel, joins us to explain why browser agents are not blocked by model capability anymore. They are blocked by identity. Kernel builds open source browser infrastructure for AI agents, which means running Chromium in sandboxed Firecracker VMs at scale and solving the part nobody designed for: an agent acting on behalf of a human, on a login page built 20 years ago for a human. Catherine walks through Kernel's Managed Auth product, an SDK that lets developers collect end user credentials so Kernel handles login and re-authentication and the LLM never touches the secret. We get into what agents inherit today (usually the user's full permissions, with no scopes and no audit trail), how ID-JAG and Enterprise Managed Auth for Claude change the picture for MCP servers and what the equivalent looks like for a browser, why multi-hop delegation chains from agent A to agent B to a Kernel browser session have no one-size-fits-all answer, and how intelligent egress networking inside the sandbox can enforce where an agent is allowed to go at the network layer. She closes on the two protocols the early web never standardized, payments and identity, and why Kernel is pushing on the second one.
