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

README.md

Example: Wiki Explorer

Visualizes Wikipedia link graphs using a force-directed layout. Explore how Wikipedia pages are connected by expanding nodes to reveal first-degree links.

Features

Force-directed graph visualization: Interactive graph powered by force-graph
Node expansion: Click any node to expand and see all pages it links to
Visual state tracking: Nodes change color based on state (blue = default, green = expanded, red = error)
Direct page access: Open any Wikipedia page in your browser

Running

Install dependencies:
```
npm install
```

Build and start the server:

npm run start:http  # for Streamable HTTP transport
# OR
npm run start:stdio  # for stdio transport

View using the basic-host example or another MCP Apps-compatible host.

Tool Input

To test the example, call the get-first-degree-links tool with a Wikipedia URL:

{
  "url": "https://en.wikipedia.org/wiki/Graph_theory"
}

Click nodes in the graph to Open (view in browser) or Expand (visualize linked pages).

Architecture

Server (`server.ts`)

MCP server that fetches Wikipedia pages and extracts internal links.

Exposes one tool:

get-first-degree-links - Returns links to other Wikipedia pages from a given page

App (`src/mcp-app.ts`)

Vanilla TypeScript app using force-graph for visualization that:

Receives tool inputs via the MCP App SDK
Renders an interactive force-directed graph
Supports node expansion to explore link relationships
