AI agents call list_directory to retrieve information from PSKit without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs only information retrieval about directory contents. It has no side effects, does not create, modify, delete, or execute anything. Even in the context of a PowerShell automation server, listing directory contents is a foundational read-only operation. The 'neural-safe' design and safety pipeline further suggest this is a low-risk information access tool.
From the tool's definition Tool description states 'List directory contents with name, type, size, and modified time' - a pure query operation that retrieves and displays filesystem metadata without modification or execution.
Attacks that exploit this kind of access
List directory contents with name, type, size, and modified time. It is categorised as a Read tool in the PSKit MCP Server, which means it retrieves data without modifying state.
Register the PSKit MCP server in PolicyLayer and add a rule for list_directory: 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 PSKit. Nothing to install.
list_directory 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_directory 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_directory. 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_directory is provided by the PSKit MCP server (nickalus12/pskit). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
