Get list of suspicious IP addresses
AI agents call get_suspicious_ips to retrieve information from Fastly NGWAF 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 and retrieves data about suspicious IPs without creating, modifying, deleting, or executing any actions. It is a read-only operation that reports security telemetry. While access to security data could inform an attack, the tool itself performs no side effects and the information is internal analytics that should already be available to authorized users managing the firewall.
From the tool's definition Tool description states 'Get list of suspicious IP addresses' - a retrieval operation with no modification capability.
