What is Skybridge?

Skybridge is an open-source TypeScript framework for building MCP (Model Context Protocol) apps. It lets developers write once and deploy across Claude, ChatGPT, VSCode, and any MCP client. The framework currently sees 100K monthly downloads. It provides a typed bridge between server tools and React widgets, making MCP development feel like building normal full-stack apps.

Application scenarios

  • Rapid prototyping

    Developers can go from a template repo to production-grade demos for partners within 24 hours.

  • Full-stack MCP development

    Build both server tools and frontend React widgets in a single, cohesive runtime.

  • Cross-platform deployment

    Write once and run across multiple MCP clients (Claude, ChatGPT, VSCode, and others).

  • Type-safe collaboration

    Server-side schema changes automatically surface as typecheck errors in the widget, reducing debugging time.

  • Customizable framework integration

    Teams can customize the framework to fit their specific stack and workflow needs.

  • Direct deployment

    Deploy apps directly to platforms like Alpic without additional configuration.

Core Features

  • Typed bridge

    `useToolInfo<"my_tool">()` knows exactly what the server handler returns, ensuring end-to-end type safety.

  • Instant typecheck feedback

    Server-side schema changes show up immediately as typecheck errors in the React widget.

  • Cohesive runtime

    One runtime environment replaces fragmenting codebases across multiple SDKs.

  • Fast iteration with dev tools

    Built-in development tools save hours of iteration time during app development.

  • Open-source TypeScript framework

    Fully open-source and written in TypeScript for modern development workflows.

  • Template repo

    A structured starting point that makes it easy to leverage with Claude Opus and Codex.

  • Cross-client compatibility

    Deploy apps to any MCP client including Claude, ChatGPT, and VSCode.

  • Customizable architecture

    The framework is highly customizable to fit different team needs and project requirements.

Target users

Skybridge is built for MCP developers and full-stack TypeScript engineers building AI-integrated applications. It's ideal for teams that need to deploy across multiple MCP clients (Claude, ChatGPT, VSCode) and want a type-safe, cohesive development environment. Early adopters include teams working with partners on production-grade demos and platforms like Alpic.

How to use Skybridge?

Start by cloning the template repo from the Skybridge GitHub repository. Use the structured template with Claude Opus or Codex to scaffold your project. Build server tools and React widgets using the typed bridge (useToolInfo<"my_tool">()). Deploy your finished MCP app directly to platforms like Alpic or to any MCP client (Claude, ChatGPT, VSCode).
