Official Model Context Protocol announcement for MCP Apps, the first production-ready MCP extension for returning interactive UI directly inside AI clients. It explains how tools declare `_meta.ui.resourceUri`, how hosts render sandboxed interfaces, and why dashboards, forms, visualizations, and multi-step workflows fit better than pure text for many agent tasks.
Zusammenfassung
Why This Standard Matters:
1. Official open extension: Establishes a cross-client way for tools to return interactive UI, not just text
2. Clear runtime model: Formalizes the tool-to-UI link through `_meta.ui.resourceUri` and `ui://` resources
3. Security story: Emphasizes sandboxed iframes, auditable messages, and host-controlled approvals
4. Broad client relevance: Framed for ChatGPT, Claude, VS Code, Goose, and other MCP hosts
5. Collection fit: Strong primary source for the shift from tool calling toward agent-native UI delivery
