What clean_empty_directories does on Mcp Windows
AI agents call clean_empty_directories to permanently remove resources in Mcp Windows, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why clean_empty_directories is rated Critical
The tool performs permanent deletion of filesystem objects (empty directories). While the scope is limited to empty directories, deletion is inherently destructive and non-reversible. On a Windows system with broad automation capabilities, this poses a high blast radius if an AI agent misconfigures the target path and recursively deletes unintended directory structures.
From the tool's definition Tool description states 'Remove empty directories recursively' — this is an irreversible deletion operation that cannot be undone once executed.
Attacks that exploit this kind of access
The rule that runs clean_empty_directories safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Windows, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For clean_empty_directories, this is the rule to start with:
clean_empty_directories is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Windows, apply this rule, and every clean_empty_directories call is checked against it from then on.
Questions about clean_empty_directories
Remove empty directories recursively. It is categorised as a Destructive tool in the Mcp Windows MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Mcp Windows MCP server in PolicyLayer and add a rule for clean_empty_directories: 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 Mcp Windows. Nothing to install.
clean_empty_directories is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the clean_empty_directories 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 clean_empty_directories. 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.
clean_empty_directories is provided by the Mcp Windows MCP server (mukul975/mcp-windows-automation). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
