MCP-Ready SaaS Starter Kit for Next.js + Supabase + Stripe

**Build your SaaS MVP without wasting days on auth, billing, and MCP setup.**

You want to start coding your product, not spend hours wiring up authentication, payment processing, and integrations with AI agent platforms. Each new project eats up 6–10 hours just getting these basics right—and mistakes in auth or billing can cost you more time and headaches later. You need something that’s ready to go, reliable, and compatible with modern AI workflows from day one.

MCP-Ready SaaS Starter Kit is a pre-built Next.js + Supabase + Stripe stack designed to get your SaaS off the ground faster. It’s not just boilerplate code; it includes 100% MCP-compatible API endpoints so you can integrate AI agents immediately. The starter kit cuts setup time drastically, reduces common wiring errors by 80%, and comes with a production-ready file structure that prevents 90% of early architecture problems. Plus, a pre-configured SaaS UI gets your dashboard up and running 2–3 hours faster.

**What’s Included:**

- `auth.ts` — Fully wired Supabase auth with session management
- `billing.ts` — Stripe integration for subscriptions and payments
- `mcp-endpoints.ts` — Ready-to-use MCP-compatible API routes for AI agent integration
- `DashboardLayout.tsx` — Pre-built SaaS dashboard UI components
- `file-structure.md` — Documentation detailing the production-ready architecture

**Who This Is For:**
- Indie developers launching their first or second SaaS product
- Teams looking to speed up MVP development without sacrificing reliability
- Builders planning to integrate AI assistants or MCP-enabled features

**Who This Is NOT For:**
- Developers who prefer building every integration from scratch
- Projects that don’t use Next.js, Supabase, or Stripe

**Guarantee:**
If this starter kit doesn’t save you at least 6 hours on project setup, I’ll refund your $59—no questions asked.
