Security audit

Supermarket Sales

Security checks across malware telemetry and agentic risk

Overview

This skill appears to fetch supermarket specials as advertised, with ordinary risks from installing Puppeteer and running web-scraping scripts.

Install only if you are comfortable running npm dependencies and Puppeteer browser automation. Review the scripts first, consider using a sandbox or container, and avoid heavy scraping that may violate supermarket site terms or trigger rate limits.

MCP Least Privilege

87% confidence
Finding
The skill instructs users to run shell commands such as npm install, npm start, node scripts/*.js, and bash scripts/fetch_sales.sh, but it declares no corresponding permissions. This creates a trust and execution-boundary problem: users or agents may execute local code with network and filesystem effects without an explicit permission model, increasing the risk of unintended command execution or abuse if the repository contents are modified or malicious.
