What AG-UI Author does

AG-UI Author lets an agent emit declarative dashboard components through the emit_ui MCP tool. Use it to show approvals, progress, choices, metrics, and diff summaries in a live AG-UI stream.

AG-UI Author is cataloged under AI Engineering on DirSkills. AG-UI Author comes from a repository tagged agent-orchestration, ai-agents, ai-coding-assistant, antigravity and claude-code.

Excerpt

Authoring generative UI over AG-UI

CAO exposes an AG-UI stream (GET /agui/v1/stream) that any dashboard — CopilotKit, the AG-UI Dojo, or a plain EventSource — renders without CAO-specific code. As an agent you can push a declarative UI intent onto that stream with the emit_ui MCP tool. The operator sees a rendered card, not raw text — and because every provider's intents render uniformly, they can't tell (and don't need to) which CLI agent produced which card.

The surface must be enabled on the server (CAO_AGUI_ENABLED=true or CAO_MCP_APPS_ENABLED=true — the two surfaces share one event source). When it is disabled, emit_ui returns {"ok": false, "reason": "AG-UI surface disabled…"} — treat that as a no-op, not an error.

This is the opening of the README. Read the full README on GitHub.
