What list_files does on Kali
AI agents call list_files to retrieve information from Kali without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why list_files is rated Low
This tool only retrieves directory contents without side effects. It is a read operation that gathers information about the filesystem state. While the container runs security tools, this specific tool does not execute code or modify data; it merely queries the filesystem. Severity is low because filesystem enumeration has limited blast radius when used in isolation.
From the tool's definition Tool name is 'list_files' and description states it 'List files in a directory inside the Kali Linux container' — a pure read operation with no modification, deletion, or execution of code.
Attacks that exploit this kind of access
The rule that runs list_files safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Kali, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_files, this is the rule to start with:
list_files is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Kali, apply this rule, and every list_files call is checked against it from then on.
Questions about list_files
List files in a directory inside the Kali Linux container. It is categorised as a Read tool in the Kali MCP Server, which means it retrieves data without modifying state.
Register the Kali MCP server in PolicyLayer and add a rule for list_files: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Kali. Nothing to install.
list_files is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_files rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for list_files. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
list_files is provided by the Kali MCP server (hannes221/kali-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
