ecommerceguide summary

MercadoLibre MCP Server gives an AI client read access to the MercadoLibre API, with tools for product descriptions, product reviews and seller reputation. It is a local stdio server run with npx -y mercadolibre-mcp, authenticated with CLIENT_ID and CLIENT_SECRET from a MercadoLibre developer application plus a SITE_ID for Argentina, Brazil, Colombia, Mexico, Uruguay or Chile. Maintained by Lumile under the MIT licence, with setup steps for Claude Desktop. The search_products tool is deprecated.

Why it stands out

Published by Lumile rather than MercadoLibre, and its search_products tool is deprecated following MercadoLibre API policy changes.

What MercadoLibre MCP Server does

ecommerceguide editorial
  • Three tools: product_description, product_reviews and seller_reputation

  • Claude Desktop config documented, plus Smithery CLI install

How ecommerce teams could use it

ecommerceguide editorial

Illustrative scenarios written by ecommerceguide from the product's documented capabilities. They are not customer case studies.

  1. A seller listing consumer electronics on MercadoLibre Brazil

    An analyst asks a Claude Desktop assistant about feedback on specific listings

    Intended outcomeThe server returns product reviews and product descriptions for those items through the MercadoLibre API

  2. A team sourcing stock from MercadoLibre sellers in Mexico

    Checking a counterparty before placing an order

    Intended outcomeThe seller_reputation tool returns that seller's reputation data from MercadoLibre

  3. A developer building an internal assistant for a MercadoLibre Argentina store

    Wiring marketplace data into an MCP client without writing an API wrapper

    Intended outcomeRuns the npm package over stdio with client credentials and a SITE_ID for the target country

Who it suits

ecommerceguide editorial

Best for

You need MercadoLibre product descriptions, reviews and seller reputation inside an MCP client and can run a local Node package with developer credentials.

Probably not for

You need product search (that tool is deprecated), write access to listings, a hosted endpoint, or marketplaces outside MercadoLibre's six supported country sites.

Business size
Any stageAn MIT-licensed open source server with no pricing or stated audience, so no scale band is supported.
