Jonathan Hefner 4ff22d0097 Fix build errors in examples (#180 ) * Update `package.json` * Add TypeScript type checking to example build scripts Add `tsc --noEmit &&` before `vite build` in all example `package.json` files to catch type errors during builds. Previously, type errors in `server.ts` files were not detected because Vite/Bun transpile without type checking. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * Make `_meta` optional in `McpUiAppResourceConfig` The `_meta` and `ui` properties were required, causing TypeScript errors when calling `registerAppResource()` without providing metadata. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * Fix Zod type compatibility in `registerAppTool()` Use `ZodRawShapeCompat \| AnySchema` from SDK's `zod-compat` module instead of raw `ZodRawShape` to resolve type errors when examples pass `ZodObject` schemas to `registerAppTool()`. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * Remove unused imports in example apps - `basic-server-react`: Remove unused `McpUiResourceTeardownResult` - `customer-segmentation-server`: Remove unused `PostMessageTransport` 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * Fix CI git install test for fork PRs Use `github.event.pull_request.head.repo.full_name` to correctly reference the fork repository when testing git installs from PRs. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.5 <noreply@anthropic.com>		2025-12-18 11:17:23 +00:00

An MCP App example with a React UI.

Overview

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 registration
mcp-app.html / src/mcp-app.tsx - React UI using useApp() hook

Getting Started

npm install
npm run dev

How It Works

The server registers a get-time tool 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.
