What is the Paas MCP server?

Connect Paas to Claude, Cursor or any other MCP client and it stops being a tab you switch to. Your agent opens a real merchant account (go_live) and takes payments the same day. 3.9% flat. The paas mcp server is what makes that connection.

What the server does

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%.

  • Site: paas.build · Docs for agents: paas.build/agents
  • React checkout: @paasbuild/react
  • Powered by UniPaaS — FCA-authorised payment institution (No. 929994)

Installation

@paasbuild/mcp on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • identify_business — Resolves a name / website / phrase into a business (uses web search)
  • go_live — Creates a real merchant account — sandbox + production — and returns scoped access tokens
  • create_checkout — Creates a checkout session and returns a payable link

Worth knowing first

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Where it fits

Among the payments and commerce options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Paas's toolset — identify_business, go_live, create_checkout — is a fair guide to whether it matches your workflow. It is maintained by UNIPaaS; worth a glance at recent repository activity before you build anything load-bearing on it.

Frequently asked questions

It connects Paas to MCP-compatible AI assistants such as Claude and Cursor, exposing 3 tools (identify_business, go_live, create_checkout) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Paas directly.
