agent-bom-scan

An open security scanner for coding agents, tool servers, packages, container images, filesystems, and software inventories. It checks for known vulnerabilities and can verify where software came from.

In plain words
What is it for?
Checking packages, scanning agent projects and container images, looking up CVEs, verifying Sigstore provenance, finding affected components, and generating an SBOM, a machine-readable list of software components.
Why use it?
It helps reveal vulnerable dependencies, risky containers, weak provenance, and the potential impact of a security issue.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

agent-bom-scan scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Reads agent configuration directorieslowAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

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 scan             # 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 scan . -f cyclonedx -o sbom.json  # generate an 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

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

agent-bom-scan is a skill published in the GitHub repository msaad00/agent-bom (31 stars, last pushed 3d ago), licensed Apache-2.0. It adds 89 tokens to every session and 2,320 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
