Enhances existing MCP servers by adding interactive HTML user interfaces to tool outputs.
This skill provides a comprehensive workflow for transforming static MCP servers into rich, interactive applications. It guides developers through the entire process of integrating the @modelcontextprotocol/ext-apps SDK, from analyzing which tools benefit most from a visual interface to setting up a single-file Vite build pipeline. By facilitating theme synchronization, host-style inheritance, and app-only helper tools, it allows developers to create seamless, sandboxed UI experiences that render directly within AI chatbot environments while maintaining text fallbacks for backward compatibility.
