WHAT IT DOES

What find_window does on macOS Simulator MCP Server

AI agents call find_window to retrieve information from macOS Simulator MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why find_window needs a policy

find_window performs window discovery and inspection only. It captures metadata about running windows but does not modify, execute, or control applications. This is equivalent to a search or list operation. The tool has minimal security risk as it only returns information about window state without taking actions.

From the tool's definition Tool description states 'Search for and locate a specific window' and 'returning detailed window information' — retrieval and query operations with no side effects.

Documented attack patterns abuse exactly the kind of access find_window gives an agent:

POLICY

How to control find_window

PolicyLayer is an MCP gateway — it sits between your AI agents and macOS Simulator MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for find_window:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "find_window": {}
  }
}

find_window is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register macOS Simulator MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
