Security checks across malware telemetry and agentic risk

Overview

This is a small, disclosed RAG memory helper that sends only caller-provided content to a user-configured endpoint.

Install only if you are comfortable sending selected memory content to the RAG_URL you configure. Use a trusted endpoint, prefer HTTPS for remote services, avoid passing secrets or private prompts unless intended, and only add cron jobs after reviewing the short scripts.

Category: MCP Least Privilege
Confidence: 88% confidence
Finding: The skill describes and facilitates outbound network access via the Python requests library and a configurable RAG_URL, but no explicit permissions are declared. That mismatch is a real security issue because users or hosting platforms may not realize the skill can send data off-system, including memory contents passed to save_memory(). In this context the capability is functionally aligned with the stated purpose, so it appears benign rather than deceptive, but it still increases data exfiltration and SSRF risk if misconfigured or abused.
