Overview
The Square MCP server exposes Square's APIs to LLM agents, covering payments, catalog, orders, customers, inventory, and bookings. It authenticates with a Square access token whose scope determines what the agent can read or change. Because it can process payments and read customer data, credential scoping and confirmation of financial actions are essential.
