paas.build MCP server
Let your AI agent take a business live on payments — no dashboard, no forms, no week-long review.
Most payment MCPs manage an account you already have. This one goes a level deeper: it creates the account. From Claude Code, Cursor, Windsurf or any MCP client, an agent can identify a business, open a real merchant account (sandbox and production, on FCA-authorised rails), and mint checkout tokens — in one session. Progressive KYB: live immediately with a cap, verification completes in the background. One rate: 3.9%.
Install
Set up the skill + slash commands (one command):
npx @paasbuild/mcp install
This writes a paas.build skill plus /paas-add-payments and /paas-check commands into your project (.claude/ + AGENTS.md), so your agent knows when and how to add payments. Then wire the tools:
claude mcp add paas-build -- npx -y @paasbuild/mcp
(or point any MCP client at https://paas.build/mcp)
Then just say: "add payments to my app."
Check your app first (private-safe)
npx @paasbuild/mcp check
Runs locally in your repo — nothing is uploaded. Tells you if you'll hit the Stripe no-company wall or need Connect to pay out your users, and how to go live instead. Public repo or a live URL instead? Use the web version at paas.build/check.

The agent never holds platform keys — only scoped tokens for the vendor it created.
Why this exists
AI agents build full products in one evening — then hit the last blocker: accepting money. Traditional merchant onboarding assumes a human filling forms and waiting days. This server makes onboarding itself agent-native. Read more: Agentic payments — agents can pay, but can they get paid?
