Security audit

scryfall-card

Security checks across malware telemetry and agentic risk

Overview

This is a straightforward Magic: The Gathering card lookup skill that queries Scryfall and does not show hidden, destructive, or credential-seeking behavior.

Install this if you want MTG card lookup support. Be aware that card names and search queries may be sent to Scryfall, and the trigger wording is broad enough that agents may invoke it for some non-MTG uses of "magic" or "card" unless the user prompt is clear.

MCP Least Privilege
Confidence
70% confidence
Finding
Without declared permissions the skill's intent is opaque and cannot be validated.

Vague Triggers

Medium
Confidence
93% confidence
Finding
The manifest description says to use the skill for 'deck building questions' and that triggers include mentions of 'Magic' or requests for 'card information.' Terms like 'Magic' and 'card information' are broad and lack scope constraints or negative examples, which could cause unintended activation outside clearly defined MTG-specific requests.
