mcp-scanner vs cc-audit
mcp-scanner: MCP Scanner is a Python tool designed to identify security findings in Model Context Protocol (MCP) servers and their associated tools. It leverages a multi-engine approach, combining Cisco AI Defense inspect API, YARA rules, and LLM-as-a-judge for comprehensive threat detection.; cc-audit: cc-audit is a security auditor designed for Claude Code skills, hooks, and MCP servers. It scans third-party Claude Code artifacts to detect security vulnerabilities such as data exfiltration and privilege escalation before installation, closing a critical security gap in the rapidly growing Claude Code ecosystem.

TL;DR
mcp-scannerSecurity & Safety · ★ 1.1k
When to choose:
- You want to check an MCP server's tools, prompts, resources and instructions before you install it.
- You want a scan that works without API keys: the YARA engine needs none.
- You want scans in CI/CD or air-gapped setups: static or offline mode reads pre-generated JSON files.
When to skip:
- You want runtime isolation or access control: a scanner reports issues but does not block calls.
- You treat a clean report as proof of safety: the README's engines can still miss problems.
- You cannot use hosted services: the LLM judge and Cisco API engines need keys.
