Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Lanjing Mercado Libre Product Selection
This skill queries Mercado Libre product, catalog, keyword, category, trend, seller, review, exchange-rate, and plan-usage data through the Nexscope gateway. The gateway exposes one unified route, `POST /lingdong/call`, and the skill selects one of 24 supported `toolName` values with matching `arguments`.
## Core Concepts
- Call only `${NEXSCOPE_PROXY_BASE}/api/v1/tools/research/lingdong/call`. Do not call the upstream Lanjing XP-MCP server directly, and do not ask the user for upstream `secret-key` / `X-API-Key` -- upstream credentials are owned by the backend.
- The request body is always `{"toolName":"...","arguments":{...}}`. The script takes this whole object as a single JSON argument.
- Field names inside `arguments` must match `references/mercado-tools.md` exactly, including camelCase names such as `siteId`, `itemId`, `productId`, `categoryId`, `runDate`, `runMonth`, `pageNo`, `pageSize`.
- Read `data` first when presenting results. Read `contentText` when `data` is text or ambiguous. Show `rawResponse` only when the user asks for raw diagnostics.

How to install
mdr add nexscope-ai/nexscope-ecommerce-skills/ecommerce.mercado-product-selection@sha256:f1df81a176f5fc87The line at the top of this page pins the label git:20260917.c57e917, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
