WHAT IT DOES

What godot_assign_resource does on Godot MCP Server

AI agents use godot_assign_resource 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 godot_assign_resource needs a policy

This tool modifies game object properties by assigning resources to nodes. While reversible (properties can be changed again), it can significantly alter game behavior, appearance, and functionality. The high severity reflects the potential blast radius if an agent mistakenly assigns incorrect resources across multiple critical nodes in a Godot project, causing rendering failures, broken audio, or broken game logic.

From the tool's definition The tool "assigns it to a property of a node" and is "useful for setting textures, materials, audio streams, etc." - these are direct modifications of node properties that change game state and asset bindings.
