Security Scanner MCP Server

Multi-engine container & system vulnerability scanning for AI agents. Wraps Trivy and Grype with cross-engine validation, SBOM generation, and IaC misconfiguration scanning.

Why This Exists

Most security MCP servers wrap a single scanner. This one wraps two — Trivy (Aqua Security) and Grype (Anchore) — and runs them against the same target to surface what each engine catches alone. Different vulnerability databases + different detection logic = broader coverage.

Key differentiator: No other MCP server offers multi-engine cross-validation.

Features

• 15 tools covering vulnerability scanning, SBOM generation, IaC checks, and database management

• Cross-engine validation — run Trivy + Grype on the same image and see what each catches alone

• MIT licensed — no AGPL encumbrance (unlike @aikidosec/mcp)

• npm-native — install via npx, works with Claude Desktop, Cursor, and any MCP client

• No cloud account required — runs locally against Docker daemon or filesystem

Prerequisites

Install at least one scanning engine:

# Trivy (recommended)
curl -sfL https://raw.githubusercontent.com/aquasecurity/trivy/main/contrib/install.sh | sh -s -- -b /usr/local/bin

# Grype (for cross-validation)
curl -sSfL https://raw.githubusercontent.com/anchore/grype/main/install.sh | sh -s -- -b /usr/local/bin

Claude Desktop / Cursor

Add to your MCP configuration:

{
  "mcpServers": {
    "security-scanner": {
      "command": "npx",
      "args": ["-y", "@supernova123/security-scanner-mcp-server"]
    }
  }
}

Standalone

Tools

Cross-Validation Example

The cross_validate tool runs both Trivy and Grype on the same Docker image and compares results:

{
  "combined_summary": {
    "total_unique_cves": 47,
    "critical": 2,
    "high": 8,
    "medium": 23,
    "low": 14
  },
  "divergence": {
    "only_in_trivy_count": 5,
    "only_in_grype_count": 3,
    "severity_mismatches": 2,
    "only_in_trivy": ["CVE-2023-1234", ...],
    "only_in_grype": ["CVE-2023-5678", ...]
  },
  "insight": "Cross-validation found 5 CVEs only in Trivy and 3 only in Grype. Using both engines gives broader coverage than either alone."
}
