# focus_window Bring a window to the foreground. Agent View of the PolicyLayer registry record for `focus_window`. HTML page: https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/focus-window ## Facts - Tool: `focus_window` - Server: Frida Game Hacking MCP (`0xhackerfren/frida-game-hacking-mcp`) — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp.md - Homepage: https://github.com/0xhackerfren/frida-game-hacking-mcp - Risk category: Execute (High risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "focus_window", "arguments": {} } } ``` ## Why focus_window is rated High This tool triggers an external OS-level operation (window focus/activation) that affects the user's desktop environment. It is an action with side effects on the system UI state, placing it in Execute. The blast radius is low since it only changes window focus. From the tool's own definition: "Bring a window to the foreground" ## Use case AI agents invoke focus_window to trigger actions in Frida Game Hacking MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
