What your AI can do with Square
Real prompts you can type the moment it's connected — no setup, no docs to read.
“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.”
How secure is the Square MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Square holds up.
Official endpoint
Operated by Square (squareup.com) at its documented MCP endpoint — not a third-party mirror or community re-host.
OAuth sign-in — your account, your rules
You grant access from your own Square account and can revoke it there at any time. gate never sees your password.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If Square adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Square's server requires OAuth, so it can't be scanned anonymously — connect it in gate and the same scan runs automatically before it goes live.
Connected in three steps

The Square MCP server at a glance
https://mcp.squareup.com/mcpQuestions, answered
Is there an official Square MCP server?
Yes — Square operates its own remote MCP server at mcp.squareup.com. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect Square to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Square in the directory. You sign in to Square via OAuth to grant access. From then on, Square's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Square runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Square MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Is it free?
Yes — you can get started with gate for free and connect Square in minutes. No credit card required.
