Agent Card

Security checks across malware telemetry and agentic risk

Overview

This skill enables real virtual-card and payment workflows, but the behavior is disclosed and matches its AgentCard purpose.

Install only if you intend to let an agent manage AgentCard payment cards. Use sandbox mode first, keep spending limits low, review card creation and checkout steps before authorizing real funds, and avoid asking the agent to reveal full card numbers or CVVs unless necessary.

Missing User Warnings

Medium
Confidence
89% confidence
Finding
The README promotes creating payment cards, checking balances, and paying for things, but it does not clearly warn users that enabling these tools gives an agent the ability to initiate financially consequential actions and potentially handle highly sensitive card data. In this context, the omission is materially risky because the skill is specifically designed to connect a remote MCP server and grant payment capabilities to an AI agent, increasing the chance of unintended charges, misuse, or unsafe disclosure of card credentials.
