WHAT IT DOES

What set_scripting_backend does on Godot

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

Parameter	Type	Required	Description
`backend`	string	—	Scripting language backend: gdscript or csharp (default: gdscript)

Parameters from the server's own tool schema.

RISK

Why set_scripting_backend is rated Medium

This tool modifies project settings (the scripting backend choice), which is a reversible configuration change. It does not execute arbitrary code, delete data, or move money. However, the severity is elevated to 'high' because changing the scripting backend could have significant downstream effects on project functionality—it affects how all scripts in the project are interpreted or compiled.

From the tool's definition Tool name 'set_scripting_backend' and description 'Set the scripting backend for the project' indicate modification of project configuration settings.

RECOMMENDED RULE

The rule that runs set_scripting_backend safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Godot, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For set_scripting_backend, this is the rule to start with:

set_scripting_backend Rate-limited

set_scripting_backend 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.

View as policy code

policy.json

{
  "version": "1",

    "set_scripting_backend": {
      "limits": [
        {
          "counter": "set_scripting_backend_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Godot, apply this rule, and every set_scripting_backend call is checked against it from then on.
