Sources and review

Checked against public documentation on . Suitability guidance is our editorial judgment; this is not a performance benchmark or an endorsement.

Vetting third-party MCP servers before letting agents use them.

Avoid if

You want scanning without any external service; the Cisco AI Defense engine needs its API, though the YARA engine does not.

About Cisco MCP Scanner

Cisco's open-source MCP Scanner checks MCP servers and tools for potential security findings using three engines that can run together or separately: YARA rules, LLM-based analysis and the Cisco AI Defense inspect API. It also scans Python dependencies for known vulnerabilities, and runs as a CLI or a REST API server.

Cisco MCP Scanner is listed in this index written primarily in Python, with 1.1k stars on GitHub. Its latest recorded repository push was in October 2026; that is not an ASE editorial review date.
