# Square in Best MCP Servers for Business

**Answer in brief:** Best for businesses that sell in person with Square.


## Resource role

In-person sales. Square's remote server at `https://mcp.squareup.com/mcp` connects to the Square API, including customers, orders and items, and signs in with OAuth and granular permissions.[1]

It reaches the full Square API through OAuth with granular permissions.[1]

## Relationship to Conecto

Square is a separate resource. Conecto doesn't make it and has no partnership with Block. Conecto is our editorial choice for a small business that wants its back office in one MCP server: a CRM, invoices, books, e-signature and a help desk, paid per call.

## The facts

- Address: `https://mcp.squareup.com/mcp`[1]
- Sign-in: OAuth with granular permissions[1]
- Data: Production only, on the remote server[1]

## What to inspect

The remote server reaches production data only. Square says to run its local server to test against a sandbox.[1]

Add the address to your client and approve the permissions in Square. To test first, run Square's local server against a sandbox account.[1]

## Who it fits

Pick it when your shop or restaurant runs on Square.
