To get more information about the current databases in use and when it was updated
AI agents call vul_db_update_status to retrieve information from Cve Search without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about the CVE database status and update timestamps. It is a read-only informational query with no side effects, minimal blast radius if misused.

PolicyLayer is an MCP gateway — it sits between your AI agents and Cve Search, and nothing reaches the server without passing your rules. This is the rule we recommend for vul_db_update_status:
{
"version": "1",
"default": "deny",
"tools": {
"vul_db_update_status": {}
}
}vul_db_update_status is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
