Security checks across malware telemetry and agentic risk

Overview

This skill is a straightforward X/Twitter search helper that uses an xAI API key and sends user search terms to xAI, with no evidence of hidden local access, persistence, or destructive behavior.

Install only if you are comfortable providing an xAI API key and sending your X/Twitter search terms to xAI. Avoid putting secrets, private business details, or sensitive personal information in search queries.

Medium

Category: MCP Least Privilege
Confidence: 93% confidence
Finding: The skill invokes a Python script, requires an API key from the environment, and performs outbound requests to the xAI/X service, but the skill file does not explicitly declare permissions for environment access and network use. This creates a transparency and policy-enforcement gap: users or platforms may not realize the skill can read secrets and contact external services, increasing the chance of unintended secret exposure or unauthorized network activity.
