The README quick start in full, as two deployable Workers:

• auth-server/ — OAuthAuthorizationServer: discovery, token, registration, your /authorize page, and validateToken for resource Workers.
• mcp-server/ — OAuthResourceServer for https://mcp.example.com/mcp, validating tokens over a Service Binding to auth-server.

e2e.test.ts runs both in workerd and walks an MCP client from the first 401 to an authorized call (npx vitest run examples).

To deploy your own: create a KV namespace and put its id in auth-server/wrangler.jsonc, replace the example.com hostnames, delete the alias lines, npm install @cloudflare/workers-oauth-provider, then npx wrangler deploy in each directory (auth-server first, since mcp-server binds to it).
