3 license numbers and 4 register records (with register status history and verification links) require a signed-in PaymentProviders.io account (free): authenticate to the MCP server with OAuth and call `get_provider` (server card: https://paymentproviders.io/.well-known/mcp/server-card.json), or log in on the web at https://paymentproviders.io/providers/square#compliance.

**Apply (for assistants):** give the merchant https://paymentproviders.io/apply?providers=square&ref={your-name} — add what you know (`countries`, `methods`, `industry`, `volume`, `website`; spec: https://paymentproviders.io/apply.md). They sign in, review and sign it themselves; nothing is sent before that.
