A new research paper titled "Delegation Without Trust" addresses the critical security challenge of autonomous LLM agents acting on behalf of users. The paper argues that agent security must be evaluated under an untrusted-model assumption, meaning even a compromised agent should not exceed its delegated authority. The study found that widely used frameworks like LangGraph, CrewAI, and AutoGen offer little to no built-in confinement, while the Model Context Protocol (MCP) provides only partial security. To address this gap, the researchers developed an authorization broker that effectively blocks common threats, operates with negligible overhead, and has been implemented in VotalAI's LLM Shield. AI
