List all currently visible windows.
AI agents call window_list to retrieve information from PC-Control MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates data about current windows. It has no side effects, does not execute code or commands, and does not modify or delete any data. While the broader server enables Execute and Destructive operations, this specific tool is strictly informational.
From the tool's definition Tool name 'window_list' and description 'List all currently visible windows' indicate a query operation that retrieves window information without modifying system state.
Attacks that exploit this kind of access
List all currently visible windows. It is categorised as a Read tool in the PC-Control MCP Server MCP Server, which means it retrieves data without modifying state.
Register the PC-Control MCP Server MCP server in PolicyLayer and add a rule for window_list: 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 PC-Control MCP Server. Nothing to install.
window_list 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 window_list 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 window_list. 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.
window_list is provided by the PC-Control MCP Server MCP server (krsnmlna1/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
