duplicate_node · Godot MCP Server MCP: Risk & Policy

WHAT IT DOES

What duplicate_node does on Godot MCP Server

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

WHY IT NEEDS A POLICY

Why duplicate_node needs a policy

Duplicating a node is a write operation that modifies the scene by creating additional data (a copy of an existing node). This is reversible—the duplicated node can be deleted. It is not destructive (no irreversible deletion), not financial, and not execute (no arbitrary code execution, though it does modify game state).

From the tool's definition Tool name 'duplicate_node' and description 'Duplicate a node in the scene' indicate it creates a new copy of an existing node, which is a reversible modification to the scene structure.

Verdict

duplicate_node Rate-limited

duplicate_node stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
