run_project · Godot MCP Server MCP: Risk & Policy

WHAT IT DOES

What run_project does on Godot MCP Server

AI agents invoke run_project 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 run_project needs a policy

Running a project executes code and scripts defined within the Godot project, triggering external operations whose effects depend on project contents and arguments. This falls under Execute rather than Write because it initiates a running process rather than merely modifying data.

From the tool's definition Tool named 'run_project' with context indicating it launches/executes a Godot game engine project. Sibling tools include 'launch_editor' and 'stop_project', confirming this tool triggers execution of external operations.
