create_scene · Godot MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_scene does on Godot MCP Server

AI agents use create_scene 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 create_scene needs a policy

Creating a scene in Godot is a write operation that generates new data structures (scene files) within a project. This is reversible (scenes can be deleted) and has no irreversible effects. Severity is medium because misuse could create unwanted project artifacts, but the impact is contained to the local project and easily corrected.

From the tool's definition Tool name is 'create_scene' and server context shows it 'managing scenes and nodes' within Godot projects. Scene creation is a reversible write operation.

create_scene Rate-limited

create_scene 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.
