In our rapidly evolving AI ecosystem, a critical missing piece has emerged: how do humans and AI agents collaborate in real-time? While we've solved agent-to-tool communication (MCP) and agent-to-agent communication (A2A), the human-agent interaction layer remained fragmented—until now.
Enter AG-UI (Agent-User Interaction Protocol), the breakthrough standard that's being called the "USB-C for AI agents." This lightweight, event-driven protocol is revolutionizing how we build collaborative AI applications, enabling seamless real-time interaction between humans and AI systems.
