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".

Available Tools

CobroYa exposes 5 MCP tools that any connected AI agent can call:

Tool	Description
`create_payment_preference`	Create a Mercado Pago checkout payment link. Returns an `init_point` URL to share with buyers. Supports `back_urls` and `notification_url`.
`get_payment`	Retrieve full details of a payment by ID, including status, amount, and payer info.
`search_payments`	Search payments with filters: `status` (approved, pending, rejected, etc.), sort order, and pagination.
`create_refund`	Issue a full or partial refund for a payment. Omit `amount` for a full refund.
`get_merchant_info`	Get the authenticated merchant's profile: user ID, nickname, and site.

Telegram Bot

CobroYa includes a ready-to-use Telegram bot: @CobroYa_bot

Self-hosting the bot

Create a bot via @BotFather and get your token.
Set environment variables:

export MERCADO_PAGO_ACCESS_TOKEN="APP_USR-..."
export TELEGRAM_BOT_TOKEN="your-telegram-bot-token"

Run:

npx cobroya-telegram

Or from source:

npm run bot

CobroYa supports WhatsApp Business Cloud API for receiving commands and sending payment notifications.

Create a Meta app at Meta for Developers and enable WhatsApp Business API.
Set environment variables:

export WHATSAPP_ACCESS_TOKEN="your-meta-graph-api-token"
export WHATSAPP_PHONE_NUMBER_ID="your-phone-number-id"
export WHATSAPP_VERIFY_TOKEN="your-webhook-verify-token"

Run the webhook server:

npm run whatsapp
# Starts on http://localhost:3000/webhook

Expose with ngrok (ngrok http 3000) and configure the webhook URL in your Meta Dashboard.

For full details on supported commands and payment notifications, see the WhatsApp documentation.

Automation Platforms

Pre-built packages for popular automation platforms are available in the packages/ directory:

n8n -- packages/n8n-nodes-mercadopago
Zapier -- packages/zapier-mercadopago
Make -- packages/make-mercadopago
Pipedream -- packages/pipedream-mercadopago

Each package wraps the CobroYa core with platform-specific configuration. See the README in each package for setup instructions.

AI Framework Adapters

LangChain (Python)

pip install langchain-mercadopago

from langchain_mercadopago import create_mercadopago_tools

tools = create_mercadopago_tools("APP_USR-...")

# Use with any LangChain agent
from langchain.agents import initialize_agent, AgentType
from langchain_openai import ChatOpenAI

agent = initialize_agent(
    tools=tools,
    llm=ChatOpenAI(model="gpt-4"),
    agent=AgentType.OPENAI_FUNCTIONS,
)
agent.run("Create a payment link for $5000 for a Python course")

PyPI

OpenAI Function Calling (TypeScript)

npm install openai-mercadopago

import { createMercadoPagoExecutor } from "openai-mercadopago";

const executor = createMercadoPagoExecutor(process.env.MERCADO_PAGO_ACCESS_TOKEN!);

// Pass executor.definitions to OpenAI's tools parameter
const response = await openai.chat.completions.create({
  model: "gpt-4",
  messages,
  tools: executor.definitions,
});

// Execute the tool call
const result = await executor.handleToolCall(
  toolCall.function.name,
  JSON.parse(toolCall.function.arguments),
);

npm

Programmatic Usage

Install as a dependency:

npm install cobroya

import { createMercadoPagoTools } from "cobroya";

const mp = createMercadoPagoTools(process.env.MERCADO_PAGO_ACCESS_TOKEN!);

// Create a payment link
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 });

// Merchant profile
const merchant = await mp.tools.get_merchant_info();

Error Handling

import { MercadoPagoError } from "cobroya";

try {
  await mp.tools.get_payment({ payment_id: "invalid" });
} catch (err) {
  if (err instanceof MercadoPagoError) {
    console.log(err.status);        // 404
    console.log(err.isNotFound);     // true
    console.log(err.isUnauthorized); // false
    console.log(err.isRateLimited);  // false
  }
}
