b4642b4338Update all documentation links from `modelcontextprotocol.github.io/ext-apps` to the new custom domain across README.md, docs/, and example READMEs. Add `cname` to the `peaceiris/actions-gh-pages` deploy action in `.github/workflows/docs.yml` so the CNAME file persists across deploys.

# Example: Integration Test Server
|
|
|
|
An MCP App example used for E2E integration testing.
|
|
|
|
## Overview
|
|
|
|
This example demonstrates all App SDK communication APIs and is used by the E2E test suite to verify host-app interactions:
|
|
|
|
- Tool registration with a linked UI resource
|
|
- React UI using the [`useApp()`](https://apps.extensions.modelcontextprotocol.io/api/functions/_modelcontextprotocol_ext-apps_react.useApp.html) hook
|
|
- App communication APIs: [`callServerTool`](https://apps.extensions.modelcontextprotocol.io/api/classes/app.App.html#callservertool), [`sendMessage`](https://apps.extensions.modelcontextprotocol.io/api/classes/app.App.html#sendmessage), [`sendLog`](https://apps.extensions.modelcontextprotocol.io/api/classes/app.App.html#sendlog), [`openLink`](https://apps.extensions.modelcontextprotocol.io/api/classes/app.App.html#openlink)
|
|
|
|
## Key Files
|
|
|
|
- [`server.ts`](server.ts) - MCP server with tool and resource registration
|
|
- [`mcp-app.html`](mcp-app.html) / [`src/mcp-app.tsx`](src/mcp-app.tsx) - React UI using `useApp()` hook
|
|
|
|
## Getting Started
|
|
|
|
```bash
|
|
npm install
|
|
npm run dev
|
|
```
|
|
|
|
## How It Works
|
|
|
|
1. The server registers a `get-time` tool with metadata linking it to a UI HTML resource (`ui://get-time/mcp-app.html`).
|
|
2. When the tool is invoked, the Host renders the UI from the resource.
|
|
3. The UI uses the MCP App SDK API to communicate with the host and call server tools.
