AI agents use migrate_code to create or modify resources in SceneView 3D & AR. 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 migrate_code 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 3D & AR.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access migrate_code gives an agent. Each links to the full case and the policy that stops it:
Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Automatically migrates SceneView 2.x Kotlin code to 3.x. Applies known renames (SceneView→Scene, ArSceneView→ARScene), replaces deprecated APIs (loadModelAsync→rememberModelInstance, Engine.create→rememberEngine), fixes LightNode trailing-lambda bug, removes Sceneform imports, and more. Returns the migrated code with a detailed changelog. Use this when a user has 2.x code that needs updating, or when you detect 2.x patterns in their code.. It is categorised as a Write tool in the SceneView 3D & AR MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the SceneView 3D & AR MCP server in PolicyLayer and add a rule for migrate_code: 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 3D & AR. Nothing to install.
migrate_code is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the migrate_code 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.
Set action: deny in the PolicyLayer policy for migrate_code. 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.
migrate_code is provided by the SceneView 3D & AR MCP server (sceneview/gateway). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
