editor_select_node

THE RISK

High Risk

This tool triggers an action in the live Godot editor via an editor bridge, changing the editor's selection state. It's not a pure read (it modifies editor UI state) and not a write to data, but rather an external operation that controls the editor environment. Misuse could interfere with an active editing session, hence medium severity.

From the tool's definition Select a node in the live Godot editor when an editor bridge is available

HOW TO CONTROL EDITOR_SELECT_NODE

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 editor_select_node:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "editor_select_node": {
      "limits": [
        {
          "counter": "editor_select_node_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

editor_select_node stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Godot Devtool — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

What does the editor_select_node tool do? +

Select a node in the live Godot editor when an editor bridge is available. It is categorised as a Execute tool in the Godot Devtool MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on editor_select_node? +

Register the Godot Devtool MCP server in PolicyLayer and add a rule for editor_select_node: 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.

What risk level is editor_select_node? +

editor_select_node is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit editor_select_node? +

Yes. Add a rate_limit block to the editor_select_node 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 editor_select_node completely? +

Set action: deny in the PolicyLayer policy for editor_select_node. 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 editor_select_node? +

editor_select_node 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.

Enforce policy on every Godot Devtool tool call.
