take_screenshot · Godot MCP Unified MCP: Risk & Policy

WHAT IT DOES

What take_screenshot does on Godot MCP Unified

AI agents invoke take_screenshot to trigger actions in Godot MCP Unified. 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 take_screenshot needs a policy

This tool executes the Godot project process to capture a screenshot. While the primary intent is to read/capture visual output, it achieves this by running/launching the game, which is an Execute-category action. Misuse could trigger unintended game logic or side effects from running the project.

From the tool's definition 'Take a screenshot of a Godot project by running it briefly' — the tool runs the Godot project (executes it) to capture a screenshot
