sessions_remove_attack
AI agents call sessions_remove_attack to permanently remove resources in CyPerf MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool performs a removal operation on sessions, which is destructive by nature—data deletion cannot be undone. While the description is empty (lowering confidence slightly), the name clearly indicates a delete/remove action in the context of security testing sessions. Destructive severity is assigned because deleted sessions cannot be recovered and represent irreversible loss of test configuration or results.
From the tool's definition Tool name 'sessions_remove_attack' indicates removal/deletion of attack sessions. The 'remove' verb combined with the testing context (CyPerf network security testing) suggests irreversible deletion of test data or session state.
