Summary
Bridges json-render's declarative UI system with the Model Context Protocol so you can serve interactive interfaces inside Claude, ChatGPT, Cursor, and VS Code. The server side registers an MCP tool that accepts json-render specs and serves a bundled React app as an HTML resource. Inside the iframe, a React hook connects via postMessage to render the spec with your component catalog. Works with shadcn components out of the box. The setup is straightforward if you're already familiar with MCP servers and Vite bundling, though you're wiring together several pieces. Honestly most useful if you're already invested in json-render and want your UIs to work across MCP clients without rewriting them.
