add_script_function · Godot Mcp Pilot MCP: Risk & Policy

WHAT IT DOES

What add_script_function does on Godot Mcp Pilot

AI agents use add_script_function to create or update resources in Godot Mcp Pilot — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Godot Mcp Pilot environment.

WHY IT NEEDS A POLICY

Why add_script_function needs a policy

This is a Write action because it creates/modifies code reversibly (functions can be removed or edited later). It is categorized as 'high' severity rather than 'Execute' because while GDScript is executable, the tool itself only writes the function definition—actual execution depends on separate invocation.

From the tool's definition Appends a new function to a GDScript file; modifies code reversibly. The description explicitly states the tool adds functionality to scripts, and GDScript is executable code in Godot projects.
