Square payment processing, inventory management, and point-of-sale integration.
mcpizy install squarenpx -y @square/mcp-serverIf Square doesn't fit your stack, these Payments MCP servers solve similar problems.
The Square MCP server is an Payments Model Context Protocol server that lets Claude Code, Cursor, Windsurf, VS Code with Copilot, and other MCP-compatible AI agents square payment processing, inventory management, and point-of-sale integration. It exposes Square's capabilities as tools the AI can call directly from your editor or CLI.
The fastest way is the MCPizy CLI: run `mcpizy install square` and MCPizy will add the server to your `.claude.json` automatically. You can also install it manually by adding an entry under `mcpServers` in `.claude.json` with the command `npx -y @square/mcp-server` and restarting Claude Code.
Yes. The Square MCP server is free and open source (see the GitHub repository linked on this page). You may still need a Square account or API key to connect the server to the underlying service, but the MCP layer itself has no MCPizy subscription cost.
Yes. Any MCP-compatible client works — including Claude Code, Claude Desktop, Cursor (via `.cursor/mcp.json`), Windsurf, VS Code with Copilot Chat, and custom agents built on the MCP SDK. The same install command targets all of them; only the config file path differs.
Once installed, your AI agent can square payment processing, inventory management, and point-of-sale integration directly inside your conversation. Typical use cases include asking Claude Code or Cursor to run Square operations, inspect results, chain Square with other MCP servers (see our Workflow Recipes), and automate repetitive payments tasks without leaving your editor.
