FAQ from Square Model Context Protocol Server (Beta)

What authentication methods does the server support?

Local mode requires a Square access token set via the ACCESS_TOKEN environment variable. The remote MCP server uses OAuth, allowing users to log in with their Square account directly without manual token management.

Can I run the server in a sandbox environment?

Yes. Set the SANDBOX=true environment variable to use Square’s sandbox environment. Alternatively, PRODUCTION=true forces production mode.

How do I restrict the server to read-only operations?

Set the DISALLOW_WRITES=true environment variable to prevent any write operations through the API.

What tools does the server expose?

The server exposes three tools: get_service_info (discover methods for a service), get_type_info (learn parameter requirements), and make_api_request (execute API calls to Square).
