The client, core and server packages become ^2.0.0 peers and client is now a required peer (App and AppBridge extend its Protocol class); server stays optional for View-only consumers. Examples move to zod ^4.2.0 to match the library peer range. The root package is not yet published at 2.0.0, so the lockfile now links the examples' @modelcontextprotocol/ext-apps dependency to the repository root instead of a registry copy. This drops the stale 1.x tarball (and its sdk 1.x peer) from the lockfile and makes scripts/link-self.mjs a no-op. |

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
server.ts- MCP server with tool and resource registrationmcp-app.html/src/mcp-app.tsx- React UI usinguseApp()hook
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.
