AI agents invoke tools_gowitness to trigger actions in Zebbern Kali MCP. 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.
Gowitness is a penetration testing reconnaissance tool that launches a headless browser to screenshot web services. It executes external operations against potentially arbitrary targets. On a Kali-based server with sibling tools like secretsdump, bloodhound, and kerberoast, this fits an active recon/Execute pattern. Empty description reduces confidence but the tool name is strongly indicative.

Documented attack patterns abuse exactly the kind of access tools_gowitness gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Zebbern Kali MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for tools_gowitness:
{
"version": "1",
"default": "deny",
"tools": {
"tools_gowitness": {
"limits": [
{
"counter": "tools_gowitness_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}tools_gowitness 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.
