Use the Square MCP server
in Claude Code

Payments, orders, catalog, and customers from your Square account. This guide connects Square to Claude Code (the terminal agent) through a governed gateway — one URL that also works in every other MCP client you use, with your rules and a full log attached.

Setup: Square in Claude Code

Claude Code adds MCP servers via the `claude mcp add` command. The gateway route takes about two minutes:

  1. Connect Square to your free gate gateway from the verified directory.
  2. In your terminal: claude mcp add gate https://gateturbo.com/api/mcp --transport http
  3. Approve the sign-in when Claude Code opens it in your browser.
  4. Square's tools now appear in every Claude Code session — with per-tool allow/ask/block rules if you want them.

What to ask once it’s connected

“What were yesterday's sales?”
“Find the orders for this customer.”
“Which catalog items sell best this month?”
“Summarize the refunds from the last 30 days.”

Why route it through a gateway

One URL, every client

The same Square connection works in Claude, ChatGPT, Cursor, VS Code too — no per-client re-wiring.

Rules before regret

Allow, ask, or block every tool Square exposes — reads can flow freely while writes require your approval.

Every call logged

A plain-language activity log of everything Claude Code did with Square — searchable, exportable, auditable.

Scanned and probed

Square passed a live handshake probe and a security scan before listing — and drift detection watches it after you connect.
