A starter TypeScript template for building MCP and ChatGPT Apps with the Skybridge framework.

Getting Started

Prerequisites

• Node.js 24+

Local Development

1. Install

npm install
# or
pnpm install
# or
bun install
# or
deno install
# or
yarn install

2. Start your local server

Run the development server from the root directory:

npm run dev
# or
pnpm dev
# or
bun dev
# or
deno task dev
# or
yarn dev

This command starts:

• Your MCP server at http://localhost:3000/mcp.
• Skybridge DevTools UI at http://localhost:3000.

3. Project structure

├── src/
│   ├── server.ts         # Server entry point
│   ├── views/            # React components (one per view)
│   ├── components/       # Shared UI components
│   ├── helpers.ts        # Shared utilities
│   └── index.css         # Global styles
├── vite.config.ts
├── alpic.json            # Deployment config
└── package.json

Create your first view

1. Add a new view

• Register a tool in src/server.ts with a unique name (e.g., my-view) using registerTool and a view config.
• Create a matching React component at src/views/my-view.tsx. The file name must match the view name exactly.

2. Edit views with Hot Module Replacement (HMR)

Edit and save components in src/views/ — changes will appear instantly inside your App.

3. Edit server code

Modify files in src/ and refresh the tool list with your MCP Client to see the changes.

Testing your App

You can test your app locally by using our DevTools UI on http://localhost:3000 while running the dev command.

To connect your app with web clients like ChatGPT or Claude, expose your server on the internet by adding the --tunnel flag. By enabling the tunnel, you'll also be able to access a playground to chat with your app and a real LLM. Learn more by reading the test guide.

Deploy to Production

Skybridge is infrastructure vendor agnostic, and your app can be deployed on any cloud platform supporting MCP.

The simplest way to deploy your app is by running the deploy command, which will push your MCP server to the Alpic cloud for free.
