FAQPage Schema
How do I build an MCP server with a React UI for AI integration?▼

To build an MCP server with a React UI, this skill scaffolds an MCP App using the MCP SDK to define server-side tools and Vite to bundle client-side React components into a single-file HTML application.

What is an MCP App and how does it expose tools to AI models?▼

An MCP App is an MCP server that exposes tools with visual React UIs. It uses Zod schemas to define tool inputs and registers UI resources, enabling interactive applications that integrate directly with AI models.

How do I scaffold a new MCP App project from scratch?▼

You scaffold a new MCP App project by using this skill to generate the pre-configured build tools and server structures, defining data fetching tools with Zod, and bundling the React application via Vite.

Does the MCP App builder require Vite to bundle React components?▼

Yes, the MCP App builder requires Vite to bundle the client-side React components into a single-file HTML format, ensuring the visual UI integrates seamlessly with the server-side MCP logic.

Can I use Zod schemas to define tools in an MCP App?▼

Yes, you can use Zod schemas to define tools in an MCP App. The skill utilizes the MCP SDK to process these schemas, registering the tools and linking them to the React UI resources.

What are the limitations of building single-file HTML MCP Apps?▼

Building single-file HTML MCP Apps bundles all React components into one file using Vite, which may limit code splitting and dynamic loading. Consider this when scaling complex visual dashboards for AI integration.
