AI agents call depguard_sbom to retrieve information from Depguard without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool reads existing project files (package.json and lock file) and generates a report (SBOM). It does not modify, delete, or execute anything — it is purely a read/analysis operation. The optional VEX embedding also only reads from the audit pipeline. Severity is low as misuse could at most expose dependency metadata.

Documented attack patterns abuse exactly the kind of access depguard_sbom gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Depguard, and nothing reaches the server without passing your rules. This is the rule we recommend for depguard_sbom:
{
"version": "1",
"default": "deny",
"tools": {
"depguard_sbom": {}
}
}depguard_sbom is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Generate a CycloneDX 1.6 Software Bill of Materials (SBOM) for an npm project. Reads package.json + lock file to enumerate direct + transitive components with PURLs and integrity hashes. Set includeVex=true to embed vulnerability data (VEX) from the audit pipeline. Use this when the user asks for an SBOM, a compliance report, or to comply with EU CRA / US EO 14028 requirements. It is categorised as a Read tool in the Depguard MCP Server, which means it retrieves data without modifying state.
Register the Depguard MCP server in PolicyLayer and add a rule for depguard_sbom: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Depguard. Nothing to install.
depguard_sbom is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the depguard_sbom rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for depguard_sbom. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
depguard_sbom is provided by the Depguard MCP server (mopanc/depguard). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Depguard, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
