AI agents call get_car_paint_shader to retrieve information from SceneView 3D & AR without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though get_car_paint_shader only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access get_car_paint_shader gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Returns a realistic Filament .mat car-paint material definition (clearcoat + optional metallic flakes) plus a Kotlin SceneView snippet showing how to compile it to .filamat and apply it to a loaded car model's material instances. Parameters are physically based: baseColor, metallic, roughness, clearcoat, clearcoatRoughness. Supports 4 finish presets (solid, metallic, pearlescent, matte) that override the PBR knobs with realistic defaults. Use this for car configurators where hand-writing a correct clearcoat material is otherwise tedious.. It is categorised as a Read tool in the SceneView 3D & AR MCP Server, which means it retrieves data without modifying state.
Register the SceneView 3D & AR MCP server in PolicyLayer and add a rule for get_car_paint_shader: 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.
get_car_paint_shader is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_car_paint_shader 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 get_car_paint_shader. 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.
get_car_paint_shader 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.
