Quick Start

An access token is required. MercadoLibre now gates almost every endpoint behind an app token (search, items, categories list, sellers, trends, currency conversion return 403/401 anonymously; only get_category works without one). Create a free application at developers.mercadolibre.com and use its access token as MERCADOLIBRE_ACCESS_TOKEN in every config below.

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "mercadolibre": {
      "command": "npx",
      "args": ["-y", "@dan1d/mercadolibre-mcp"],
      "env": { "MERCADOLIBRE_ACCESS_TOKEN": "APP_USR-..." }
    }
  }
}

Claude Code

claude mcp add mercadolibre -e MERCADOLIBRE_ACCESS_TOKEN=APP_USR-... -- npx -y @dan1d/mercadolibre-mcp

Cursor

Add to .cursor/mcp.json:

{
  "mcpServers": {
    "mercadolibre": {
      "command": "npx",
      "args": ["-y", "@dan1d/mercadolibre-mcp"],
      "env": { "MERCADOLIBRE_ACCESS_TOKEN": "APP_USR-..." }
    }
  }
}

Windsurf

{
  "mcpServers": {
    "mercadolibre": {
      "command": "npx",
      "args": ["-y", "@dan1d/mercadolibre-mcp"],
      "env": { "MERCADOLIBRE_ACCESS_TOKEN": "APP_USR-..." }
    }
  }
}

With authentication (required for all tools except get_category)

Add your access token to the env block (the Claude Desktop / Cursor / Windsurf snippets above need the same env):

{
  "mcpServers": {
    "mercadolibre": {
      "command": "npx",
      "args": ["-y", "@dan1d/mercadolibre-mcp"],
      "env": {
        "MERCADOLIBRE_ACCESS_TOKEN": "APP_USR-..."
      }
    }
  }
}

Once configured, ask your AI assistant things like: "Search for iPhone 15 on MercadoLibre" or "What are the trending searches in Argentina?" or "Show me details for item MLA1234567890"
