Quick Start with AI

CobroYa is an MCP (Model Context Protocol) server. Add it to your AI tool in one step -- no cloning, no building. Just provide your Mercado Pago access token.

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "cobroya": {
      "command": "npx",
      "args": ["-y", "cobroya"],
      "env": {
        "MERCADO_PAGO_ACCESS_TOKEN": "APP_USR-..."
      }
    }
  }
}

Claude Code

claude mcp add cobroya -- npx -y cobroya \
  --env MERCADO_PAGO_ACCESS_TOKEN=APP_USR-...

Cursor

Add to .cursor/mcp.json in your project root:

{
  "mcpServers": {
    "cobroya": {
      "command": "npx",
      "args": ["-y", "cobroya"],
      "env": {
        "MERCADO_PAGO_ACCESS_TOKEN": "APP_USR-..."
      }
    }
  }
}

Windsurf

Add to your Windsurf MCP configuration:

{
  "mcpServers": {
    "cobroya": {
      "command": "npx",
      "args": ["-y", "cobroya"],
      "env": {
        "MERCADO_PAGO_ACCESS_TOKEN": "APP_USR-..."
      }
    }
  }
}

Once configured, ask your AI assistant things like: "Create a payment link for $5000 for a Python course" or "Show me today's approved payments".

const pref = await mp.tools.create_payment_preference({
  title: "Premium Plan",
  quantity: 1,
  currency: "ARS",
  unit_price: 5000,
});
console.log(pref.init_point); // Checkout URL to share with the buyer

// Search approved payments
const payments = await mp.tools.search_payments({ status: "approved", limit: 10 });

// Get payment details
const payment = await mp.tools.get_payment({ payment_id: "123456789" });

// Full refund
await mp.tools.create_refund({ payment_id: "123456789" });

// Partial refund
await mp.tools.create_refund({ payment_id: "123456789", amount: 500 });
