How does the UI match the look and feel of the host application?

The skill implements host-styling handlers that sync CSS variables for fonts, colors, and spacing from the host (like Claude Desktop) to your UI.

What is an 'app-only' tool in the context of MCP?

App-only tools are helper functions used exclusively by the UI (for tasks like polling or pagination) that the AI model does not need to invoke directly.

Does adding a UI replace my existing text-based MCP tools?

No, it enhances them. The skill ensures your tools maintain a text-only fallback for standard clients while providing a rich UI resource for compatible hosts.

Which frontend frameworks can I use with this skill?

You can use any framework supported by Vite, including React, Vue, Svelte, Preact, and Solid, as well as Vanilla JavaScript.

Is a separate build process required for the UI?

Yes, the skill sets up a Vite-based pipeline that bundles your UI into a single HTML file, which is then served as an MCP resource.

디자인 도구

Transforms standard MCP tools into interactive visual applications using the MCP Apps SDK and Vite-based UI resources.

This skill provides a structured framework for enhancing existing Model Context Protocol (MCP) servers with rich, interactive user interfaces. By integrating the @modelcontextprotocol/ext-apps SDK, it enables developers to convert text-only tools into visual experiences like dashboards, maps, and document viewers. It automates the setup of build pipelines using Vite, handles host-theming via CSS variables, and ensures backward compatibility for text-only clients through structured content fallbacks, making it essential for building production-grade MCP applications.
