MCP support

The server exposes identify_business, go_live, and create_checkout to MCP clients, and can also be reached at https://paas.build/mcp.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

Details

From the project README

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.

Tools

ToolWhat it does
identify_businessResolves a name / website / phrase into a business (uses web search)
go_liveCreates a real merchant account — sandbox + production — and returns scoped access tokens
create_checkoutCreates a checkout session and returns a payable link

Configuration

EnvDefaultNotes
PAAS_PROXYhttps://paas.buildThe paas.build API (secrets stay server-side)

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?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
