Overview

AI-generated overview

Lets an AI agent identify a business, open a real merchant account and create checkout links and subscription plans through paas.build.

What you can do
  • Identify a business from a name, website or phrase, using web search
  • Open a real merchant account in sandbox and production and return scoped access tokens
  • Create checkout sessions that return payable links
  • Create recurring subscription plans and subscription checkouts, and list a vendor's subscriptions for reconciliation
  • Install a project skill and slash commands, and run a local check of whether an app will hit payment onboarding blockers
When to use it
Use it when an agent-built app needs to start accepting payments and you want the merchant account itself created from the assistant session rather than through a dashboard and forms. It suits quick sandbox-to-production onboarding for a small business or side project.
Requirements
Runs as a local npm package over stdio, so Node.js is needed; a remote endpoint is also mentioned. The PAAS_PROXY environment variable sets the API base (default paas.build). Subscription tools need the vendor's access_token returned by account creation. An MCP client such as Claude Code, Cursor or Windsurf is assumed.
Before you install
go_live creates a real production merchant account and returns access tokens, and checkout and subscription tools create payable links and recurring charges, so money can move. Progressive KYB means the account goes live with a cap before verification completes. The install command writes files into your project (.claude/ and AGENTS.md). A flat 3.9% rate applies.

Installation

In SourceWeft

  1. Open Paas Build Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

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):

bash
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:

bash
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)

bash
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
create_subscription_planCreates a recurring plan (week/month/year) and returns a planId. Needs the vendor's access_token
create_subscription_checkoutFirst charge + stored card + auto-renew for a plan; returns a payable link. Needs access_token
list_subscriptionsLists the vendor's subscriptions for reconciliation. Needs access_token

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?

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
