Material Design MCP Server

A Cloudflare Worker that exposes an MCP (Model Context Protocol) server for browsing the Material Design 3 documentation.

Features

• list_pages — List all documentation pages from the Material Design sitemap

• get_page — Navigate any Material Design page and get its content as clean Markdown

Architecture

• Runtime: Cloudflare Workers (TypeScript, nodejs_compat)

• Router: Hono

• Browser automation: Browser Run (Playwright binding)

• Markdown conversion: Workers AI toMarkdown()

• MCP transport: Streamable HTTP (@modelcontextprotocol/server v2)

Because m3.material.io is a JavaScript-heavy SPA, the worker uses Playwright to wait for the client-side <article> element to render before extracting content.

Prerequisites

• Node.js 18+

• pnpm

• A Cloudflare account with:

  • Browser Run enabled

  • Workers AI enabled

Setup

# Install dependencies
pnpm install

# Generate TypeScript types from wrangler.jsonc
pnpm run gen:cf-types

Development

# Start local dev server (connects to remote Cloudflare services)
pnpm dev

The MCP endpoint is available at http://localhost:8787/mcp.

Deployment

pnpm deploy

Connect an MCP Client

{
    "mcpServers": {
        "material-design": {
            "url": "https://material-mcp.your-account.workers.dev/mcp"
        }
    }
