How are the UIs rendered in the host application?

UIs are rendered in a sandboxed iframe using HTML resources that are registered on your MCP server and fetched by the host when a tool is called.

How do I handle styling to match the host application?

The skill demonstrates how to use host-provided CSS variables for colors, fonts, and spacing to ensure your UI looks native to the environment it's running in.

Does adding UI break existing text-only clients?

No, this skill guides you to maintain text fallbacks in the content array so your tools remain fully functional and compatible with non-UI hosts.

What frontend frameworks can I use with this skill?

The skill provides guidance and templates for various frameworks including Vanilla JS, React, Vue, Svelte, Preact, and Solid.

Can the UI communicate directly with the MCP server?

Yes, the UI can call specific 'app-only' helper tools via the SDK for tasks like polling data or fetching additional chunks without triggering an LLM response.

Enriches existing Model Context Protocol servers with interactive HTML interfaces for enhanced data visualization and user interaction.

This skill streamlines the process of transforming text-only MCP tools into rich, interactive visual experiences. It provides comprehensive guidance for analyzing server architectures, setting up Vite-based build pipelines, and implementing the MCP Apps SDK. By pairing standard tools with HTML resources, developers can render complex charts, interactive maps, and media players directly within supported host interfaces. The skill ensures tools remain backward-compatible with text-only clients while providing high-fidelity UI enhancements, including support for streaming partial inputs and thematic styling that matches the host environment.
