Ido & Liad (MCP Apps): UI Moves Into the Chat
The MCP Apps co-founders explain the standard — defined with Anthropic and OpenAI and now live in Claude and ChatGPT — that lets tools send UI into chat so users no longer need to visit web apps like Sentry. They argue agents don't need human-oriented pagination and filtering, but domain-specific 'last mile' flows such as venue seat picking or flight check-in will remain, and they flag open questions of trust, liability and host control over third-party UIs. They point developers to the MCP Apps repo in the modelcontextprotocol GitHub org and mcpui.dev.
