       | Introducing AG-UI; the Agent-User Interaction Protocol.
       | 
       | AG-UI is an open, lightweight, event-based protocol that
       | standardizes how AI agents connect to fronted-end applications.
       | 
       | After a year of one-off, CopilotKit <> Agent frameworks
       | collaborations, we decided to ship a standard, and open way for
       | agents to connect to apps.
       | 
       | We are launching with day 0 integrations with LangChain, Mastra,
       | CrewAI and AG2 with more partnerships on the way.
       | 
       | How AG-UI works: - Creates a unified, two-way bridge between
       | backend agents and frontend apps - Works with any event transport
       | (SSE, WebSockets, webhooks) - Supports 16 standardized event
       | types for common agent-user interactions
       | 
       | Where AG-UI fits in the agent protocol landscape: - MCP: for
       | agent--tools communication - A2A/ACP: for agent--agent
       | communication - AG-UI: for agent--human interaction in
       | applications
       | 
       | We launched the protocol yesterday, and have been blown away by
       | the reception. We have the first working group this Friday, to
       | help expand and steer the direction of the protocol.
       | 
       | Check out the repo to get started!

       | Wow, after MCP, this is the new thing!
       | 
       | let me give it a try

       | I don't understand what it can be used for. Is this for
       | accessibility? Or a new UI building paradigm?

       | I had kinda wondered about this for a while - I called it "MWP -
       | model workload protocol" - a client-agnostic (sms, whatsapp, in-
       | app, react components) way to display what an agent is doing
       | 
       | - working - thinking - calling tools - hit an error - needs human
       | input - needs human approval
       | 
       | etc etc etc
