create_animation_tree · Godot MCP Unified MCP: Risk & Policy

WHAT IT DOES

What create_animation_tree does on Godot MCP Unified

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

WHY IT NEEDS A POLICY

Why create_animation_tree needs a policy

This tool creates (instantiates) a new node object in the scene hierarchy, which is a reversible write operation typical of game development tooling. It does not execute arbitrary code, delete data, or trigger financial transactions. The severity is medium because incorrect animation tree configurations could break game mechanics, but the operation is reversible through node deletion or undo operations.

From the tool's definition create_animation_tree explicitly creates a new AnimationTree node in the Godot scene graph, which is a persistent modification to the game project state.

create_animation_tree Rate-limited

create_animation_tree 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.

FAQ

Questions about create_animation_tree

What does the create_animation_tree tool do? +

Create an AnimationTree node for advanced animation control including state machines and blend spaces. It is categorised as a Write tool in the Godot MCP Unified MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_animation_tree? +

Register the Godot MCP Unified MCP server in PolicyLayer and add a rule for create_animation_tree: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Godot MCP Unified. Nothing to install.

What risk level is create_animation_tree? +

create_animation_tree is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_animation_tree? +

Yes. Add a rate_limit block to the create_animation_tree rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block create_animation_tree completely? +

Set action: deny in the PolicyLayer policy for create_animation_tree. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides create_animation_tree? +

create_animation_tree is provided by the Godot MCP Unified MCP server (pierrealexandreguillemin-a11y/godot-mcp-unified). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
