Mexico Payments (Mercado Pago — OXXO cash)

The two tools have completely distinct purposes: one creates a payment link and the other queries its status. There is no overlap or ambiguity between them.

Both tools follow a verb_noun pattern: 'create_payment_link' and 'query_payment_status'. While 'query' is slightly less common than 'get', the pattern is consistent and clear.

With only two tools, the server feels thin for a payment service. While it covers the basic create and check status flows, typical payment services also include refund or cancellation, making this borderline.

The server covers creating a payment link and checking its status, but lacks any update, cancel, or refund capabilities. Missing common payment lifecycle operations reduces completeness.
