simulate_mouse_move · Godot MCP Server MCP: Risk & Policy

WHAT IT DOES

What simulate_mouse_move does on Godot MCP Server

AI agents invoke simulate_mouse_move to trigger actions in Godot MCP Server. 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.

WHY IT NEEDS A POLICY

Why simulate_mouse_move needs a policy

This tool triggers an external operation (mouse movement simulation) within the running Godot game environment. It executes a simulated input event that can affect game state depending on what the game does with mouse input. This is an Execute-category action as it drives runtime behavior in an external application.

simulate_mouse_move Rate-limited

simulate_mouse_move 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.

What risk level is simulate_mouse_move? +

simulate_mouse_move is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit simulate_mouse_move? +

Yes. Add a rate_limit block to the simulate_mouse_move 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.

How do I block simulate_mouse_move completely? +

Set action: deny in the PolicyLayer policy for simulate_mouse_move. 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.

What MCP server provides simulate_mouse_move? +
