AG-UI Protocol Overview - AG-UI protocol has become the standard for building front-end Agentic apps where Agents are part of the interface [1] - AG-UI defines a common interface between Agents and the UI layer, remaining Agent framework agnostic [2] Key Features of AG-UI - AG-UI enables streaming token-level updates, showing tool progress in real time, sharing mutable state, and pausing for human input [2] - Developers can spin up a full-stack AG-UI app directly from CLI and visualize A2A interactions [2] - Pydantic AI is now AG-UI compatible [2] Development Efficiency - Building AG-UI frontends is now 10x faster with a plug-and-play interface [1][2] - A fully revamped contributor flow is available for developers [2] Agent Connectivity - MCP connects agents to tools, A2A connects agents to other agents, and AG-UI connects agents to users [2]

Agentic Apps Development - AG-UI protocol simplifies front-end Agentic app development, making it 10x easier [1] - AG-UI is becoming the standard for apps where Agents are part of the interface [1] Agent Communication Protocols - MCP connects agents to tools [1] - A2A connects agents to other agents [1]

Building front-end Agentic apps just got 10x easier (open-source)!If you're building apps where Agents are part of the interface, not just running in the background, AG-UI protocol has become the standard.For context:- MCP connects agents to tools- A2A connects agents to other agents- AG-UI connects agents to usersIt defines a common interface between Agents and the UI layer.AG-UI itself is Agent framework agnostic, and it lets you:- stream token-level updates- show tool progress in real time- share mutable ...
