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", "server"]
    }
  }
}

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")

Agentic Workflows

Use tool chains, not isolated calls, when the user asks for a decision:

User intent	Recommended sequence	Output
"Is this MCP safe to install?"	`registry_lookup` -> `check` -> `blast_radius` when a package/version is known	concise allow/warn/block recommendation with evidence
"Gate this PR"	`scan` with SARIF output and fail on high/critical findings	SARIF for code scanning plus non-zero gate result
"Audit my fleet inventory"	validate inventory -> `scan`/`agents` with JSON output -> `context_graph`	findings plus graph-ready JSON
"What changed since last run?"	current scan -> `diff` against prior JSON	new/resolved/persistent findings
"What should I fix first?"	`scan` -> `blast_radius` -> `remediate` plan	prioritized plan only; no file writes

Pick output by consumer: SARIF for CI, JSON for automation/graph, HTML or Markdown for human review, CycloneDX/SPDX for SBOM consumers.

For CLI gates, prefer:

agent-bom agents --format sarif --output agent-bom.sarif --fail-on-severity high

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
agent-bom agents
