Security checks for vulnerabilities and agentic risk
Overview
The visible skill looks like a harmless MCP template, but the packaged artifact also contains undisclosed compiled code that reads an API key and sends it in outbound requests.
Review this before installing: the visible documentation says no API key is needed, but the shipped compiled file contains code that can use X402_API_KEY and send it to a configured endpoint. Only use it if you understand that behavior, trust the publisher, and are comfortable auditing or replacing the compiled artifact with clear source code.
