THE RISK

Medium Risk

Why desktop_add_scale_animation needs a policy

The tool's name implies a Write operation (adding an animation to a scene). The description is truncated and warns the tool is broken, which lowers confidence. Since it 'adds unregistered attributes,' it modifies scene state, placing it in Write. Severity is medium because misuse could corrupt AR scene configuration, but it's reversible. Confidence is reduced due to the broken/incomplete description.

From the tool's definition Tool name 'desktop_add_scale_animation' suggests adding/modifying animation attributes to a scene, but the description says '⚠️ BROKEN - DO NOT USE! Adds unregistered attributes causing' (truncated).

POLICY

How to control desktop_add_scale_animation

PolicyLayer is an MCP gateway — it sits between your AI agents and 8th Wall MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for desktop_add_scale_animation:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "desktop_add_scale_animation": {
      "limits": [
        {
          "counter": "desktop_add_scale_animation_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

desktop_add_scale_animation 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.
