TL;DR
The SaaS Starter Stack bundles 6 MCPs (Stripe, Supabase, GitHub, Vercel, Linear, Notion) that cover 90% of the operational surface of a B2B SaaS. Install all six with one command; Claude Code then becomes your second engineer handling billing, database, deploy, and project management in a single conversation. Replaces ~$500/mo of fragmented tools.
The SaaS Starter Stack
Everything to launch a B2B SaaS in a weekend
Install the whole stack
$ mcpizy install stripe supabase github vercel linear notionOne command installs and configures all 6 MCPs for Claude Code, Cursor, Windsurf, or any MCP-compatible client.
Why this stack?
Every B2B SaaS needs the same five capabilities on day one: user auth + database (Supabase), billing (Stripe), deploys (Vercel), source control (GitHub), and project management (Linear). Notion is the seventh wheel that holds it all together with specs, decisions, and marketing copy. This stack is the minimum viable tech backbone — trusted by thousands of solo and early-stage SaaS founders.
What makes this combo magical with MCPs: Claude Code (or Cursor) can read from every tool and write back to every tool in one conversation. 'Add Pro tier' stops being a 4-day project touching Stripe + Supabase + Vercel + GitHub and becomes a 2-hour prompt.

What this stack lets you do
Day 1: Ship the MVP
- 1Spec the core feature in Notion (Claude drafts from a 1-line description)
- 2Scaffold schema in Supabase (migration auto-generated from the spec)
- 3Wire Stripe checkout for 1 paid plan (Claude generates the full flow)
- 4Push to GitHub, Vercel preview deploy auto-opens
- 5Create Linear tickets for week-2 polish
Weekly: Ship a feature
See recipe- 1Pick a ticket from Linear
- 2Claude reads the spec in Notion and implements in the repo
- 3Supabase migration drafted + tested locally
- 4GitHub PR opened, Vercel preview for review
- 5Merge → Vercel prod deploy → Linear closed
Handle a customer issue
See recipe- 1Support email arrives
- 2Claude queries Stripe for billing state of the customer
- 3Claude queries Supabase for user's app state
- 4If it's a bug, Linear ticket created with full context
- 5If it's a billing issue, Stripe refund/retry applied in-conversation
Estimated value
Replaces ~$500/mo of SaaS tools (Intercom, Linear seats, DevRev, Chartmogul, Retool) for an early-stage founder. All 6 MCPs themselves are free — you only pay for the underlying services you already use.
Frequently asked questions
Is this stack overkill for a single-founder project?
No — every tool in it has a free tier that covers you until $10K MRR. Most solo founders use exactly this stack; the MCPs just make it 3x more productive.
Can I swap Vercel for something else?
Yes — Netlify, Railway, Fly.io all have MCPs (Railway is community-maintained). Vercel is the default because it has the tightest Next.js integration and the mature MCP server.
What if I don't use Supabase — can I substitute Postgres + Clerk?
Absolutely. Clerk MCP + Postgres MCP is a valid alternative. Supabase is picked as the default for the 'one MCP covers it all' simplicity, but many founders prefer the Clerk+Postgres split for production.
How much does it cost to actually run this stack?
$0/mo on free tiers (Supabase free, Vercel Hobby, GitHub free, Linear free up to 250 issues, Notion free for personal, Stripe pay-as-you-go). Typical cost at $5K MRR: ~$80/mo total across all six services.
Do I need to install all six at once?
No — start with Stripe + Supabase + GitHub (core 3) and add the others as you grow into them. The install command is modular: `mcpizy install stripe supabase github` gets you moving in 5 minutes.
