6eb82b5562Rename `startServer` to `startStreamableHTTPServer` and add a new `startStdioServer` helper to make the transport type explicit. Remove the `ServerOptions` interface in favor of reading `PORT` directly from the environment inside the function (defaulting to `3001`). Also update Python examples to default to port `3001` for consistency. 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
Key Files

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.
