AI agents call get_scene_tree to retrieve information from Godot Devtool without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns structural information about a scene's node hierarchy. It performs no writes, deletions, code execution, or external operations. The action is entirely read-only inspection of project metadata. Severity is low because unauthorized access to scene structure poses minimal direct risk to a running project or data integrity.
From the tool's definition Tool name 'get_scene_tree' and description 'Return the node tree for a Godot scene' indicate pure data retrieval with no modification or side effects.
Documented attack patterns abuse exactly the kind of access get_scene_tree gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Godot Devtool, and nothing reaches the server without passing your rules. This is the rule we recommend for get_scene_tree:
{
"version": "1",
"default": "deny",
"tools": {
"get_scene_tree": {}
}
}get_scene_tree is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Return the node tree for a Godot scene. It is categorised as a Read tool in the Godot Devtool MCP Server, which means it retrieves data without modifying state.
Register the Godot Devtool MCP server in PolicyLayer and add a rule for get_scene_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 Devtool. Nothing to install.
get_scene_tree is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_scene_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.
Set action: deny in the PolicyLayer policy for get_scene_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.
get_scene_tree is provided by the Godot Devtool MCP server (wangdiandao/godot-devtool). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
