Overview

This skill does what it advertises: it saves user-provided URLs or memos to Cubox using a user-configured API URL.

Install only if you want the agent to save selected content to Cubox. Treat CUBOX_API_URL like a password, avoid logging or sharing it, and do not send confidential, regulated, or secret content unless you are comfortable storing it in Cubox.

Medium

• Category: MCP Least Privilege
• Confidence: 94% confidence
• Finding: The skill explicitly requires access to an environment variable containing a secret API URL and uses network-capable scripts, but it does not declare any permissions to reflect those capabilities. This creates a transparency and consent problem: users or hosting platforms may not realize the skill can read sensitive credentials and send data off-box, increasing the risk of unintended secret exposure or data exfiltration if the scripts are modified or misused.
