WHAT IT DOES

What set_light_param does on Godot

AI agents use set_light_param 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
`param`	string	Yes	Light parameter (e.g. "energy", "color", "shadow_enabled")
`value`	string	Yes	New value
`light_name`	string	Yes	Name of the light node
`scene_path`	string	Yes	Path to .tscn scene file

Parameters from the server's own tool schema.

RISK

Why set_light_param is rated Medium

This tool modifies engine configuration state (light parameters) but does not execute arbitrary code, delete data, or produce financial effects. The change is reversible through subsequent set operations. Categorized as Write rather than Execute because it targets a specific, bounded parameter rather than arbitrary code execution.

From the tool's definition Tool name 'set_light_param' and description 'Set light parameter' indicate modification of light properties in the Godot Engine. This creates or modifies engine state (light parameters) reversibly.

RECOMMENDED RULE

The rule that runs set_light_param 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_light_param, this is the rule to start with:

set_light_param Rate-limited

set_light_param 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.

{
  "version": "1",
  "default": "deny",
  "tools": {
    "set_light_param": {
      "limits": [
        {
          "counter": "set_light_param_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_light_param call is checked against it from then on.

FAQ

Questions about set_light_param

What does the set_light_param tool do? +

What parameters does set_light_param accept? +

set_light_param accepts 4 parameters: param, value, light_name, scene_path. Required: param, value, light_name, scene_path. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on set_light_param? +

Register the Godot MCP server in PolicyLayer and add a rule for set_light_param: 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. Nothing to install.

What risk level is set_light_param? +

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

Can I rate-limit set_light_param? +

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

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

set_light_param is provided by the Godot MCP server (@yanhuifair/godot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
