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.

Features

Tools

• search_products - DEPRECATED: Search products in MercadoLibre, and return a list of products. (No longer available due to API policy changes)
  • query - The search query
  • category - The category to search in
  • filters - The filters to apply
• product_reviews - Get product reviews
• product_description - Get product description
• seller_reputation - Get seller reputation

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.
