crawley_scan · Kali MCP: Risk & Policy

WHAT IT DOES

What crawley_scan does on Kali

AI agents invoke crawley_scan to trigger actions in Kali. 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.

WHY IT NEEDS A POLICY

Why crawley_scan needs a policy

The tool executes a web crawler (Crawley) against web targets. This is an active operation that sends HTTP requests to external systems, making it an Execute category action. While crawling itself is primarily a read/reconnaissance activity, it constitutes an active external operation whose scope and impact depend on arguments provided.

From the tool's definition 'Execute Crawley web crawler' - the tool explicitly runs/executes a web crawler against external targets

crawley_scan Rate-limited

crawley_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.
