AI agents call get_window_geometry to retrieve information from PyMCPAutoGUI without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves geometric information (likely width, height, x/y coordinates) about a window without modifying any state. It has no side effects and serves only to query existing data. The absence of a description is offset by the clear naming convention and the server context where similar 'get_' operations are read-only.
From the tool's definition Tool name 'get_window_geometry' indicates it retrieves window dimensions/position data. No description provided, but the sibling tools and server context show this is a GUI automation server where 'get_*' and similar query operations are non-mutating.
Documented attack patterns abuse exactly the kind of access get_window_geometry gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and PyMCPAutoGUI, and nothing reaches the server without passing your rules. This is the rule we recommend for get_window_geometry:
{
"version": "1",
"default": "deny",
"tools": {
"get_window_geometry": {}
}
}get_window_geometry is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_window_geometry. It is categorised as a Read tool in the PyMCPAutoGUI MCP Server, which means it retrieves data without modifying state.
Register the PyMCPAutoGUI MCP server in PolicyLayer and add a rule for get_window_geometry: 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 PyMCPAutoGUI. Nothing to install.
get_window_geometry 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 get_window_geometry 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 get_window_geometry. 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.
get_window_geometry is provided by the PyMCPAutoGUI MCP server (kitfactory/pymcpautogui). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from PyMCPAutoGUI, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
