Skybridge

Skybridge is an open source, full stack TypeScript and React framework for building MCP Apps and MCP servers. An MCP App pairs a set of tools exposed to an AI model with a React interface that renders inside the chat client, and Skybridge is designed so the same app runs in Claude, ChatGPT, VS Code and other clients that support MCP Apps. Developers define tools on the server with schema validation, then write React views that read the tool output through hooks modeled on react query. Types are inferred from the server tool definition through to the view. The framework ships a local emulator, hot module reload, a public tunnel for connecting a local app to Claude and ChatGPT, an automatic app audit, and a library of example apps for areas such as online retail, travel and software as a service. It also publishes skills and a command line interface intended for coding agents that build MCP Apps. It is aimed at TypeScript and React developers who want to ship apps inside AI assistants without writing separate integrations for each one. A new project starts with the npm create skybridge command. The framework is free and open source. The site does not publish any paid plans or prices.
