AI Agent Supply Chain Security MCP Servers — Scanning, Vetting, and Securing MCP
At a glance: 66% of 1,808 scanned MCP servers had security findings. Counterfeit packages caught BCC'ing emails. Tool poisoning exfiltrates data through hidden descriptions.
MCP Scanners
Snyk Agent Scan (1,900 stars) — auto-discovers MCP configs, 15+ threat types (tool poisoning, prompt injection, rug pulls). CLI + continuous monitoring.
Cisco MCP Scanner (850 stars) — three engines: YARA rules, LLM-as-judge, Cisco AI Defense API. Behavioral code analysis.
Secure Infrastructure
Docker MCP Gateway (1,300 stars) — containerized MCP execution with SBOM, provenance, isolation. 300+ verified servers in curated catalog.
Dependency Security
Socket MCP (90 stars) — zero-setup public endpoint at mcp.socket.dev. Security scores for npm/PyPI packages.
agent-bom (10 stars) — 32 MCP tools for agent self-assessment. CVE scanning, blast radius, 14-framework compliance, runtime behavioral detection.
Threats
Tool poisoning, rug pulls, typosquatting, credential exposure (88% require creds, only 8.5% use OAuth). 66% of scanned servers had findings.
Rating: 3.5/5
Major vendors investing (Snyk, Docker, Cisco). Most tools scan from outside — agents can't self-protect. Protocol lacks signing, permissions, attestation primitives.
