Most MCP server tutorials in 2026 stop at npx create-mcp and a Hello-world tool. That's a demo. This guide takes you to a production server that actually takes money: Cloudflare Workers + KV + Stripe checkout + per-user quotas + AI Gateway + Vectorize RAG + SSE streaming, listed in the official MCP Registry.
