AI agents use generate_scene to create or modify resources in Sceneview. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

Without a policy, an AI agent could call generate_scene repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Sceneview.

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access generate_scene gives an agent. Each links to the full case and the policy that stops it:

Every attack above starts with a tool call. PolicyLayer checks each one against your policy first, so generate_scene only ever does what you allow.

What does the generate_scene tool do? +

[PRO] Generates a complete, compilable SceneView{} or ARSceneView{} Kotlin composable from a natural language description. Parses 40+ object types (furniture, vehicles, animals, food, buildings, nature), quantities ("two chairs", "3 spheres"), environment (indoor/outdoor/dark), and mode (3D or AR). Returns working Kotlin code with proper engine setup, model loading, lighting, and ground plane. Use this when a user says "build me a scene with..." or describes a 3D scene they want to create.. It is categorised as a Write tool in the Sceneview MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on generate_scene? +

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

What risk level is generate_scene? +

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

Can I rate-limit generate_scene? +

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

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

generate_scene is provided by the Sceneview MCP server (SceneView/sceneview). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Sceneview tool call.
