WHAT IT DOES

What ffuf_scan does on Nyxstrike

AI agents invoke ffuf_scan 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.

RECOMMENDED RULE

The rule that runs ffuf_scan 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 ffuf_scan, this is the rule to start with:

ffuf_scan Rate-limited

ffuf_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.
