The problems Claude Code builders actually hit

You’ve seen these. So have we.

✗ The guides assume you already have an account

“Add Stripe in an afternoon” tutorials start AFTER approval — the merchant account itself is the missing step.

source: builder guide →

with paas.build: Our MCP creates the account: identify_business → go_live → tokens. No prior approval.

✗ Stripe’s MCP manages, it can’t open

The Stripe MCP server operates an EXISTING account (customers, refunds, invoices) — it cannot get you approved to sell.

source: Composio toolkit docs →

with paas.build: paas-build MCP goes one level deeper — it provisions the account itself.

✗ Billing is the fiddliest mile

End-to-end SaaS build logs consistently show billing as the slowest, most re-worked part of the project.

source: build log →

with paas.build: Subscriptions, saved cards and renewals wired by the agent from our docs.

Three steps

From prompt to first payment

1. Install the MCP / skill

One command (below). Claude gets three tools: identify_business, go_live, create_checkout.

2. Say what you want

"Take my business live." Claude identifies your business (web search), creates sandbox + production vendors, and hands you scoped tokens — no dashboard.

3. First payment from the terminal

Ask for a checkout link, pay with a sandbox card, watch it land in your merchant portal. Then flip to production.

FAQ

Is this real or a demo?

Real. go_live creates an actual merchant account on UniPaaS (FCA-authorised, No. 929994) — capped until verification completes in the background.

What about other MCP clients?

Any MCP client works — Cursor, Windsurf, Cline, or your own agent. The server speaks plain stdio JSON-RPC and calls our public API.

What does it cost?

3.9% flat. Sandbox is free forever.
