WHAT IT DOES

What run_tool does on Nyxstrike

AI agents invoke run_tool to trigger actions in Nyxstrike. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why run_tool is rated High

The tool name 'run_tool' is generic but appears designed to execute arbitrary tools on a penetration testing platform. Given the server's purpose (offensive security) and sibling tools that generate payloads, run attacks, and assess vulnerabilities, this likely executes security testing operations with high blast radius.

From the tool's definition Tool named 'run_tool' with empty description on 'AI Powered penetration testing Platform for offensive security research' server alongside tools like 'ai_generate_attack_suite', 'aircrack_ng', and 'ai_vulnerability_assessment'.

RECOMMENDED RULE

The rule that runs run_tool safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Nyxstrike, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For run_tool, this is the rule to start with:

run_tool Rate-limited

run_tool stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
