Security Findings1

Severity	Finding	Layer	Location
HIGH	Unversioned external MCP dependency introduces supply chain risk The skill explicitly depends on an external Multi-Cloud Platform (MCP) server hosted at `https://rube.app/mcp` without specifying a version or pinning the behavior of its exposed tools. The `SKILL.md` states that 'Tool schemas change', indicating that the interface and functionality of the underlying Blackboard automation tools are dynamic and controlled by the external `rube.app` service. This introduces a significant supply chain risk: a compromise or malicious update to `rube.app` could alter tool schemas or behavior, potentially leading to arbitrary code execution, data exfiltration, or other vulnerabilities through the skill's interaction with the MCP, without any changes to the skill's local definition. Implement version pinning for the Rube MCP integration, if supported by the platform, or establish a trusted channel for schema updates. Consider vendoring critical tool schemas or implementing strict validation against known good schemas to prevent unexpected changes. Thoroughly vet and continuously monitor the `rube.app` endpoint for security and integrity.	LLM	SKILL.md:1
