AG-UI Protocol Launches Own GitHub Organization — Open Standard for Agent-User Interaction Ships Microsoft Agent Framework, LangGraph, and CrewAI Integrations

GitHub·high signal

The AG-UI (Agent-User Interaction) protocol now has its own GitHub org (ag-ui-protocol/ag-ui) with a growing framework ecosystem including first-party React and Angular clients plus community clients in Go, Rust, and Java. Microsoft published official AG-UI integration docs for its Agent Framework on Microsoft Learn, positioning AG-UI as the missing layer between agents and frontends that MCP and A2A don't cover.
