AI agents call notepad_close to permanently remove resources in WinScript — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Closing Notepad without saving could irreversibly discard unsaved data. Based on sibling tools like 'excel_close' (which likely closes without saving) and the pattern in this automation server, 'notepad_close' likely closes the application, potentially losing unsaved work. However, the empty description lowers confidence.
From the tool's definition Tool name is 'notepad_close'; description is empty and uninformative.
Documented attack patterns abuse exactly the kind of access notepad_close gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and WinScript, and nothing reaches the server without passing your rules. This is the rule we recommend for notepad_close:
{
"version": "1",
"default": "deny",
"hide": [
"notepad_close"
]
}notepad_close disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Register the WinScript MCP server in PolicyLayer and add a rule for notepad_close: 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 WinScript. Nothing to install.
notepad_close 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 notepad_close 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 notepad_close. 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.
notepad_close is provided by the WinScript MCP server (ravaniroshan/winscript-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from WinScript, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
