WHAT IT DOES

What sessions_add_attacks does on CyPerf MCP Server

AI agents use sessions_add_attacks to create or update resources in CyPerf MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your CyPerf MCP Server environment.

WHY IT NEEDS A POLICY

Why sessions_add_attacks needs a policy

Based on the tool name, 'sessions_add_attacks' likely adds attack configurations to test sessions in the CyPerf network security testing platform. This suggests a Write operation (adding/modifying session configuration). However, the empty description significantly reduces confidence. The 'attacks' component relates to security test scenarios, not actual network attacks.
