Overview

This instruction-only skill is aligned with its stated purpose of generating MCP server scaffolds and does not request credentials, persistence, or hidden access.

Use this in a new or clearly chosen project directory, review the generated package files and MCP config before running them, and provide credentials only later if your specific generated server requires them.

Vulnerability Patterns

• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access
• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code
• Excessive Agency: Unrestricted Tool Access, Autonomous Decision Making, Scope Creep

Missing User Warnings

Medium

• Confidence: 94% confidence
• Finding: The skill explicitly instructs generating a full project scaffold with multiple files, but it does not require user confirmation, safe output boundaries, or warnings about creating or overwriting files. In an agent setting, this can lead to unintended filesystem modifications, clobber existing code, or cause large-scale writes based on ambiguous prompts, especially because the skill is designed to autonomously bootstrap projects.
