Captured live from the server via tools/list.

create_payment_link

Create a payment link in UYU for Uruguay via Mercado Pago. Buyer pays with cards, Abitab / Redpagos cash, Mercado Pago wallet. Returns a hosted checkout URL the buyer opens to pay — payment completes automatically, no confirm step. Bring your own credentials via HTTP header (x-mercadopago-access-token; free test credentials from mercadopago.com developers never move real money). Money always flows buyer→Mercado Pago→merchant; this service never touches funds.

amount_uyu	number	required	Amount in UYU (decimals allowed), e.g. 500. Minimum 50.
description	string	required	What this payment is for (shown to the buyer, ≤200 chars)
customer_email	string	optional	Optional buyer email.
reference_id	string	optional	Your unique order reference (≤40 chars). Auto-generated if omitted.
success_url	string	optional	Optional https URL to send the buyer to after payment.

query_payment_status

Check whether a Uruguay payment (created by create_payment_link) has been paid. Queries Mercado Pago directly — pull-based, no webhook needed. paid=true when status is PAID (Mercado Pago APPROVED).

Parameters1

external_reference

string

required

The external_reference returned by create_payment_link

  "type": "object",
  "properties": {

    }
  },
  "required": [
    "external_reference"
  ]
}

refund_payment

Refund a paid payment (created by create_payment_link). Full refund by default; pass amount for a partial refund where supported. Refunds respect the same owner policy guardrails (x-agentpay-max-amount) as payments — the amount is checked before anything is sent to the gateway.

Parameters2

external_reference	string	required	The external_reference of the paid payment (same id used by query_payment_status)
amount	number	optional	Optional partial-refund amount in the local currency major unit. Omit for a full refund.

Uruguay Payments MCP — let AI agents accept payments in Uruguay

Use it in 60 seconds

Paste this into your MCP client config (Claude Desktop, Cursor, Windsurf, or any MCP-capable agent):

json

{
  "mcpServers": {
    "uruguay-payments": {
      "type": "http",
      "url": "https://mcp-uy.wishpool.app/mcp"
    }
  }
}

Nothing to install. Credentials, when you need them, travel as HTTP headers on each request and are never stored — see the threat model.

Or run it yourself

Would you rather not send production credentials to a server you do not control? Deploy this identical code to your own account and point your agent at your own URL:

bash

git clone https://github.com/junter1989k-ai/uruguay-payments-mcp && cd uruguay-payments-mcp && npx vercel --prod

`query_payment_status`	Pull-based status check; `paid=true` when PAID.

Develop
