Agent Interaction

AG-UI

Agent User Interaction Protocol

Community Global CopilotKit and the AG-UI community Since 2025

An event based protocol between agent backends and user facing applications, covering streaming output, tool calls, state updates and human approval steps.

Its compliance relevance is human oversight. Where the AI Act expects a person to be able to intervene, the interaction protocol is where that intervention is actually implemented and logged.
