Busca información detallada de una vulnerabilidad CVE por su identificador.
AI agents call search_cve_by_id to retrieve information from MCP Cybersecurity Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves vulnerability data from the CIRCL CVE API based on a CVE identifier. It is a read-only operation that returns information without side effects. The context (Blue Team/SOC security analysis) confirms this is a lookup utility for security research, with no capability to modify, execute, or delete data. Severity is low because reading CVE information poses minimal risk even if misused by an AI agent.
From the tool's definition Tool name 'search_cve_by_id' and description 'Busca información detallada de una vulnerabilidad CVE por su identificador' (Search detailed information about a CVE vulnerability by its identifier) indicates a query/retrieval operation.
Attacks that exploit this kind of access
Busca información detallada de una vulnerabilidad CVE por su identificador. It is categorised as a Read tool in the MCP Cybersecurity Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Cybersecurity Server MCP server in PolicyLayer and add a rule for search_cve_by_id: 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 MCP Cybersecurity Server. Nothing to install.
search_cve_by_id 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_cve_by_id 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_cve_by_id. 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_cve_by_id is provided by the MCP Cybersecurity Server MCP server (josemiteba/mcp-cybersecurity-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
