AI agents invoke send_key_to_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.
The tool name suggests it sends keyboard input to a window/process, which is an external operation triggering effects in another process. On a game hacking/reverse engineering server with capabilities like code injection and function hooking, sending keys to windows could trigger arbitrary actions in target processes.

PolicyLayer is an MCP gateway — it sits between your AI agents and Frida Game Hacking MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for send_key_to_window:
{
"version": "1",
"default": "deny",
"tools": {
"send_key_to_window": {
"limits": [
{
"counter": "send_key_to_window_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}send_key_to_window stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

send_key_to_window. It is categorised as a Execute tool in the Frida Game Hacking MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Frida Game Hacking MCP server in PolicyLayer and add a rule for send_key_to_window: 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 Frida Game Hacking MCP. Nothing to install.
send_key_to_window is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

send_key_to_window is provided by the Frida Game Hacking MCP server (0xhackerfren/frida-game-hacking-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
