AI agents call browser_list_sessions to retrieve information from Kali Security MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays information about active browser sessions. It performs no side effects, creates no resources, executes no code, and modifies no state. While the broader Kali security context involves penetration testing, this specific tool is purely informational.
From the tool's definition Tool name 'browser_list_sessions' and description '列出所有活跃的浏览器会话' (list all active browser sessions) indicates a query/retrieval operation.
Documented attack patterns abuse exactly the kind of access browser_list_sessions gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Kali Security MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for browser_list_sessions:
{
"version": "1",
"default": "deny",
"tools": {
"browser_list_sessions": {}
}
}browser_list_sessions is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
