AI agents call search_vulnerabilities to retrieve information from Vulnerability Registry MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries a vulnerability database and returns filtered results. It retrieves information without modifying, deleting, or executing anything. The flexible search criteria and sorting by CVSS score are characteristic of a read-only query operation.
From the tool's definition Tool description states it 'Search and filter vulnerabilities' and 'Returns matching vulnerabilities' — core read operations with no side effects. The word 'Search' indicates retrieval of data from a vulnerability database.

Search and filter vulnerabilities with flexible criteria. All filters are optional and can be combined. Returns matching vulnerabilities sorted by CVSS score (highest first). Use for questions like. It is categorised as a Read tool in the Vulnerability Registry MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Vulnerability Registry MCP Server MCP server in PolicyLayer and add a rule for search_vulnerabilities: 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 Vulnerability Registry MCP Server. Nothing to install.
search_vulnerabilities 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 search_vulnerabilities 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 search_vulnerabilities. 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.
search_vulnerabilities is provided by the Vulnerability Registry MCP Server MCP server (orcohen5/vulnerability-registry). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
