Agent Bom Scan Agent Skill

agent-bom-scan — AI Supply Chain Vulnerability Scanner

Checks packages for CVEs, scans container images natively, verifies package

provenance via Sigstore, scans filesystems, and generates SBOMs.

Install

pipx install agent-bom
agent-bom agents             # discover agents and scan dependencies
agent-bom check langchain==0.1.0  # check a specific package with version
agent-bom image nginx:1.25   # scan container image (native)
agent-bom fs .               # scan filesystem packages
agent-bom sbom .             # generate SBOM
agent-bom verify agent-bom   # verify Sigstore provenance
agent-bom where              # show all discovery paths

As an MCP Server

{
  "mcpServers": {
    "agent-bom": {
      "command": "uvx",
      "args": ["agent-bom", "mcp"]
    }
  }
}

When to Use

• "check package" / "is this package safe"
• "scan image" / "scan container"
• "verify" / "check provenance"
• "is this safe" / "CVE lookup"
• "scan dependencies"
• "blast radius"
• "generate SBOM"

Tools (8)

| Tool | Description |

|------|-------------|

| check | Check a package for CVEs (OSV, NVD, EPSS, KEV) |

| scan | Full discovery + vulnerability scan pipeline |

| blast_radius | Map CVE impact chain across agents, servers, credentials |

| remediate | Prioritized remediation plan for vulnerabilities |

| verify | Package integrity + SLSA provenance check |

| diff | Compare two scan reports (new/resolved/persistent) |

| where | Show MCP client config discovery paths |

| inventory | List discovered agents, servers, packages |

Examples

# Check a package before installing
check(package="langchain", version="0.1.0", ecosystem="pypi")

# Map blast radius of a CVE
blast_radius(cve_id="CVE-2024-21538")

# Full scan
scan()

# Verify package provenance
verify(package="agent-bom")

Guardrails

• Show CVEs even when NVD analysis is pending or severity is unknown — a CVE ID is still a real finding.
• Treat UNKNOWN severity as unresolved, not benign — it means data is not yet available.
• Do not modify any files, install packages, or change system configuration.
• Only public package names and CVE IDs leave the machine for vulnerability database lookups.
• Ask before scanning paths outside the user's home directory.

Privacy & Data Handling

# Step 1: Install
pip install agent-bom

# Step 2: Review redaction logic BEFORE scanning
# sanitize_env_vars() replaces ALL env var values with ***REDACTED***
# BEFORE any config data is processed or stored:
# https://github.com/msaad00/agent-bom/blob/main/src/agent_bom/security.py#L159

# Step 3: Verify package provenance (Sigstore)
agent-bom verify agent-bom

# Step 4: Only then run scans
