MercadoLibre MCP Server

An MCP server that provides access to MercadoLibre API.

IMPORTANT: due to changes in MercadoLibre's API policies, it is no longer possible to access their search API. As a result, we have had to deprecate the search_products tool. This change is in compliance with MercadoLibre's new restrictions on API usage. Other tools remain functional and will continue to be supported.

Prerequisites

You'll need a MercadoLibre Client ID and Client Secret to use this server. You can get one for free at https://developers.mercadolibre.com/, create an application and get the credentials.

Once you have the credentials, you can set the CLIENT_ID and CLIENT_SECRET environment variables. And theres also the need to set the SITE_ID environment variable to the site you want to use.

        "CLIENT_SECRET": "",
        "SITE_ID": ""

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:

npm run inspector

The Inspector will provide a URL to access debugging tools in your browser.
