Clerk Nextjs Skills

This gets Clerk authentication running in Next.js 16 with the App Router, handling the proxy.ts migration from the old middleware.ts pattern. The skill covers the full setup from installing dependencies and configuring environment variables to protecting routes and reading user data in both client and server components. It also walks through building an MCP server with Clerk auth using @vercel/mcp-adapter and @clerk/mcp-tools, which is useful if you're building AI agents that need authenticated access to your Next.js app. The matcher config and route protection patterns are spelled out clearly, so you won't waste time figuring out why your auth isn't firing on certain routes.
