Security audit

MTG Wiki (English)

Security checks across malware telemetry and agentic risk

Overview

This MTG reference skill is coherent and disclosed; its main caution is that card lookups may contact third-party MTG APIs.

Install only if you are comfortable with MTG lookup terms being sent to mtgch or Scryfall when API-backed searches are used. Review the linked GitHub repository before cloning it or running its Python scripts for the full local database.
