Create application

Applications are registered entities within Mercado Pago that act as a unique identifier for managing the authentication and authorization of your integrations. They represent the link between your development and Mercado Pago and constitute the first stage in carrying out the integration.

To create an application, you have three options available: with an AI agent from your code editor, with the Mercado Pago Developers Assistant, or manually from the integration Panel.

Create with AI

Create with the Assistant

Create manually

You can use our AI resources to create your application from your IDE or agent in 2 steps. The agent will take care of creating the application in the integration panel and guiding you through the entire configuration.

To do this, you have two options: installing the Mercado Pago Plugin, available for Claude Code and Codex, or configuring the Mercado Pago MCP Server, available for editors such as VS Code and Cursor. Follow the instructions for the option you choose.

Plugin

Claude Code

Run the following command to install the Mercado Pago plugin for Claude Code.

bash
claude plugin install mercadopago@claude-plugins-official

Once installed, run the /mp-connect command to authorize the agent's access to your Mercado Pago account.

Codex

Run the following commands to install the Mercado Pago plugin for Codex.

bash
codex plugin marketplace add mercadopago/mercadopago-codex-marketplace
codex plugin add mercadopago@mercadopago-codex-marketplace

Once installed, run the /mp-connect command to authorize the agent's access to your Mercado Pago account.

MCP

VS Code

Add the following configuration to your mcp.json file.

json
{
  "mcp": {
    "servers": {
      "mercadopago-mcp-server": {
        "type": "http",
        "url": "https://mcp.mercadopago.com/mcp"
      }
    }
  }
}

Cursor

Add the following configuration to your mcp.json file.

json
{
  "mcpServers": {
    "mercadopago-mcp-server": {
      "url": "https://mcp.mercadopago.com/mcp"
    }
  }
}

Finally, ask the agent to create your application in Mercado Pago. If you'd like, you can copy and paste the following prompt.

plain
I want to integrate with Mercado Pago. Recommend the ideal payment solution for my project, create the application, and guide me through the integration.

You can complete the integration with AI support. If you need help, check the Integrate with AI guide.

In Integrations, you can view all your applications. Select one to access the resources and settings available to manage it.

Access test credentials

Test credentials let you configure and validate the integration without processing real payments. They are created automatically with the application.

To view them, follow these steps:

1. Go to Integrations and select the application.
2. Select Test in the environment selector at the top of the screen.
3. Access the credentials in either of the following ways:
   • In Home, locate the Credentials block.
   • In the side menu, select Credentials.

In both cases, you will find the Public Key and Access Token for the test environment, with options to copy them.

For these integrations, the test Access Token starts with the APP_USR prefix. Before copying a credential, verify that the selector displays the Test environment.

For more information, see the Credentials documentation.
