WHAT IT DOES

What nuclei_scan does on Hexstrike Ai

AI agents invoke nuclei_scan to trigger actions in Hexstrike Ai. 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 nuclei_scan is rated High

Nuclei is a well-known open-source vulnerability scanner that actively probes targets with exploit templates. On a server explicitly designed for offensive security and automated pentesting, nuclei_scan almost certainly executes active scanning/exploitation attempts against targets.

From the tool's definition Tool name 'nuclei_scan' combined with server context: 'autonomously run 150+ cybersecurity tools for automated pentesting, vulnerability discovery, bug bounty automation'

RECOMMENDED RULE

The rule that runs nuclei_scan safely

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

nuclei_scan Rate-limited

nuclei_scan 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.
