Square MCP Server

MCPOfficialOpen SourceApache-2.054.5

by square • APIs & Integration

A Model Context Protocol (MCP) server that lets AI assistants discover and call Square APIs (locally or via Square's hosted MCP) for payments, customers, orders, and more.

Example Use Cases

1
Discover available Square API services and methods programmatically (use get_service_info to list services and methods).
2
Inspect parameter schemas and requirements before making calls (use get_type_info to view request shapes and required fields).
3
Execute operations against Square (payments, orders, customers, webhooks, etc.) using make_api_request, with support for sandbox or production and hosted OAuth authentication.

Description

This project implements a Square Model Context Protocol server to expose Square's APIs to AI agents in a standardized way. It supports a hosted remote MCP (with OAuth) and a local server mode (using an access token and optional sandbox), and provides discovery and request tools such as get_service_info, get_type_info, and make_api_request. The server integrates with assistant clients like Goose and Claude Desktop and is autogenerated from Square's OpenAPI spec to keep API coverage broad and consistent.
