MCP Apps brings full tools into Claude

Anthropic’s November 10 update expands Claude’s public-preview support for MCP Apps, letting compatible connectors open full interactive tools beside the chat or fullscreen. Developers can ship app tools and embedded sites through an open extension designed for other compliant hosts too.

// ANALYSIS

MCP Apps moves MCP from text-based plumbing toward a portable app runtime. The promise is powerful, but interoperability will depend on host support, permission UX, and how much functionality survives inside a sandboxed iframe.

–`ui://` resources let MCP tools deliver HTML interfaces with bidirectional tool communication.
–The same app can target Claude, ChatGPT, VS Code, and other compliant clients, though host support still varies. [Official repo](https://github.com/modelcontextprotocol/ext-apps)
–Claude’s expanded support enables full-screen workflows, embedded sites, and direct edits inside connected tools.
–Sandboxed iframes, content-security policies, predeclared domains, auditable JSON-RPC, and user approval provide meaningful safety guardrails. [Claude Help Center](https://support.claude.com/en/articles/13454812-use-interactive-connectors-in-claude)
