Claude Code is where the agent-native story is fully true: install our MCP server, say "take my business live", and watch the account, tokens and checkout appear in your terminal.

Install the MCP server in Claude Code

One command, three tools

Claude Code gets identify_business, go_live and create_checkout. Use the npm package (stdio) or point at our hosted server (streamable HTTP).

# npm package (stdio) — official registry: io.github.UNIPaaS/paas-build-mcp claude mcp add paas-build -- npx -y @paasbuild/mcp

# or the hosted remote server — no install claude mcp add --transport http paas-build https://paas.build/mcp

Add --scope user to make it available in every project. Verify with claude mcp list, then say: "take my business live".

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.
