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 Your integration, you will be able to view the list of all your created applications and access the Integration data for each of them.

Access test credentials

After creating your application, the test credentialsUnique access keys that we use to identify an integration in your account, linked to your application. For more information, see the link below.Credentials will also be automatically created. Use the test credentials to perform all necessary configurations and validations in a secure test environment.

When accessing test credentials, the following credential pairs will be displayed: Public KeyPublic key used in the frontend to access information and encrypt data. You can access it through Your integrations > Integration data > Tests > Test credentials. and the test Access TokenPrivate key of the application created in Mercado Pago, that must be used in the backend. You can access it through Your integrations > Integration data > Tests > Test credentials.. The test Access Token starts with the prefix APP_USR, just like your production Access Token.
