AI agents call suricata_query_alerts to retrieve information from Zeek without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only query tool that retrieves and filters alert data from Suricata logs without any side effects. It searches pre-existing security monitoring data using filters (signature, severity, IPs, protocol, time range) and returns results. There is no data modification, code execution, or destructive operation involved. The blast radius of misuse is limited to information disclosure of security logs.
From the tool's definition Tool description states it "Search[es] Suricata IDS/IPS alerts" and "Returns the most recent alerts matching the criteria." The verbs are search and filter with no modification, creation, deletion, or execution described.
