DCC-MCP Skills Creator

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed DCC-MCP skill authoring helper that creates and validates skill packages without hidden persistence, credential use, or unrelated data access.

Install this only if you want an agent to create or modify local DCC-MCP skill package files. Review the target parent directory before using the scaffold tool, and use the pinned verified install procedure only with a commit ID from a trusted review record.

A.I.G

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Lp1

High
Category
MCP Least Privilege
Confidence
75% confidence
Finding

The skill uses 'network' capability that is not listed in its permissions. This may indicate deceptive intent or missing permission declarations.

No source excerpt is available for this finding.

Skill Enumeration

Medium
Category
Agent Snooping
Confidence
80% confidence
Finding

Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.

# DCC-MCP Skills Creator

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
77% confidence
Finding

The section titled 'Python 3.7 Policy' states that all authored skills must declare compatibility with Python 3.7+ when installed into certain hosts. This is a natural-language policy constraint that forces a specific runtime compatibility requirement broadly, without presenting it as an optional or user-selectable constraint in this document.
