Korea Payments (Toss Payments — cards / KakaoPay·NaverPay / virtual accounts) MCP server

Create a Korea payment link in KRW via Toss Payments (토스페이먼츠), a major Korean payment gateway. Methods: card (카드 — the checkout window also shows easy-pay wallets like KakaoPay 카카오페이 / NaverPay 네이버페이 / Toss Pay when enabled on the merchant contract), virtual_account (가상계좌), transfer (계좌이체 instant bank transfer), mobile_phone (휴대폰 carrier billing). Returns a hosted checkout URL the buyer opens. IMPORTANT Toss flow: after the buyer authenticates in the checkout window, you MUST call confirm_payment within 10 minutes to complete the payment (poll query_payment_status; when status is IN_PROGRESS, confirm). Bring your own Toss Payments secret key via the x-toss-secret-key header (free test keys from developers.tosspayments.com; test_sk_/test_gsk_ keys never move real money). Money always flows buyer→Toss Payments→merchant; this service never touches funds.

Check the status of a Korea payment (created by create_payment_link). Fetches the payment from Toss Payments directly — a reliable pull-based alternative to webhooks. Statuses: READY (buyer has not finished), IN_PROGRESS (buyer authenticated — call confirm_payment within 10 minutes!), WAITING_FOR_DEPOSIT (virtual account issued, awaiting deposit), DONE (paid), CANCELED / PARTIAL_CANCELED / ABORTED / EXPIRED.

Complete (approve) a Korea payment after the buyer authenticated in the Toss Payments checkout window. Required final step of the Toss flow: call this within 10 minutes of the buyer finishing (status IN_PROGRESS), passing the same payment_key, order_id and amount used at creation — the amount match is a built-in tamper check. On success status becomes DONE (or WAITING_FOR_DEPOSIT for virtual accounts until the buyer deposits).
