A2H: Agent-to-Human Protocol for AI Agent
New protocol lets AI agents discover and contact humans across platforms using standardized 'Human Cards'.
Researchers led by Zhiyuan Liang propose the A2H (Agent-to-Human) protocol, a foundational standard for integrating humans into AI agent systems. It introduces three components: Human Cards for identity registration, a Formal Communication Schema, and a Unified Messaging Abstraction. This allows autonomous AI agents to discover, address, and interact with humans as resolvable entities across different messaging platforms, moving agents from isolated systems to human-connected infrastructures.
Why It Matters
Enables seamless human-in-the-loop workflows for complex AI agent tasks, improving oversight and collaboration.
