## What it does

The server exposes 22 tools from the Mercado Libre API. Product search and item details, category lookup plus category prediction from a title, trending searches, order handling and shipment tracking, shipping labels as PDF or ZPL.

Seller-side actions are there too: change stock, price, status or title on a listing, reply to a buyer question, message a buyer after the sale, set up a price discount promotion. Seller reputation and a product's average rating are readable as well.

Auth runs on OAuth2, so you need an access token from the developer portal and the `MELI_ACCESS_TOKEN` variable before anything works. The optional `MELI_SITE_ID` defaults to MLB for Brazil; switch it to MLA for Argentina or MLM for Mexico.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `MELI_ACCESS_TOKEN` — keys and tokens: ask the human for the values, never commit them or put them in shared files.
