Skybridge

Skybridge is a full-stack React framework for building MCP (Model Context Protocol) apps. It lets developers create interactive tools and views that live inside AI assistants like Claude, ChatGPT, and VSCode. Instead of building separate integrations for each platform, you write your app once with Skybridge and it works across all major MCP clients. The framework handles the messy parts — abstracting away platform differences so your app behaves consistently whether someone accesses it through Claude's interface or ChatGPT's.

What makes Skybridge stand out is its developer experience. You get a local emulator that mimics how your app will look in Claude and ChatGPT, complete with hot module reload — edit a React component and see the change instantly in your AI client without restarting anything. There's also a public tunnel command that exposes your dev server with a stable HTTPS URL, so you can test on any device including mobile. The built-in server audit checks your app against Claude and ChatGPT submission guidelines, flagging issues like missing authentication or slow response times. The framework uses tRPC-style type inference, so your React views automatically know the shape of data coming from your MCP server tools.

Skybridge is built for developers who want to create apps that live inside AI chat interfaces. If you're building a travel booking widget, a data dashboard, or any interactive tool that users access through an AI assistant, this framework gives you a structured way to do it. The example library includes production-ready templates for e-commerce, travel, and SaaS apps. It's particularly useful for teams shipping MCP apps to multiple AI platforms at once, since Skybridge handles the compatibility layer.
