THE RISK

Why generate_vuln_report needs a policy

This tool generates a report by aggregating and formatting vulnerability data. It is a read/query operation that synthesizes existing information into a structured output. There are no side effects, deletions, or external operations triggered. Severity is low since misuse would at most expose vulnerability information already accessible through other tools on this server.

POLICY

How to control generate_vuln_report

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 generate_vuln_report:

policy.json

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

generate_vuln_report 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.

How do I enforce a policy on generate_vuln_report? +

Register the CVE MCP Server MCP server in PolicyLayer and add a rule for generate_vuln_report: 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 CVE MCP Server. Nothing to install.

What risk level is generate_vuln_report? +

How do I block generate_vuln_report completely? +

Set action: deny in the PolicyLayer policy for generate_vuln_report. 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.

What MCP server provides generate_vuln_report? +

generate_vuln_report is provided by the CVE MCP Server MCP server (mukul975/cve-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every CVE MCP Server tool call.

Start from CVE MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
