To get a JSON with all the vulnerabilities per vendor and a specific product
AI agents call vul_vendor_product_cve 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 queries vulnerability information from the CVE-Search database. It performs a lookup operation that returns data without creating, modifying, deleting, or executing code. No financial transactions or irreversible changes are involved. The tool is purely informational, making it a Read category with low severity.
