WHAT IT DOES

What get_vendor_advisory does on CVE MCP Server

AI agents call get_vendor_advisory to retrieve information from CVE MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why get_vendor_advisory needs a policy

This tool performs a read-only query across vendor advisory databases to retrieve CVE-related intelligence. It has no side effects, does not execute code or commands, does not modify data, and does not commit financial transactions. The only argument is a CVE identifier used for lookup.

From the tool's definition The tool 'Fetch vendor security advisories' retrieves information about CVE advisories from Microsoft, Red Hat, and Ubuntu. It queries existing data (patch availability and affected products) without modifying, deleting, or executing any operations.

POLICY

How to control get_vendor_advisory

PolicyLayer is an MCP gateway — it sits between your AI agents and CVE MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_vendor_advisory:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_vendor_advisory": {}
  }
}

get_vendor_advisory is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register CVE MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
