79670b4dcdApply host-provided safe area insets as padding on main containers across all examples. This ensures content doesn't render under system UI elements like phone notches. React apps use `useState` + `onhostcontextchanged` handler with initial fetch via `getHostContext()` in `useEffect`. Vanilla JS apps apply padding in the handler and invoke it after `connect()`. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Opus 4.5 <noreply@anthropic.com> |

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()hook - App communication APIs:
callServerTool,sendMessage,sendLog,openLink

Getting Started
npm install
npm run dev
How It Works
- The server registers a
get-timetool with metadata linking it to a UI HTML resource (ui://get-time/mcp-app.html). - When the tool is invoked, the Host renders the UI from the resource.
- The UI uses the MCP App SDK API to communicate with the host and call server tools.
