AI agents call get_viewport_camera to retrieve information from Unreal without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves camera metadata (location and rotation) from the Unreal Engine editor viewport. It is a read-only operation with no side effects, no code execution, and no data modification. The severity is low because camera position information poses minimal security risk if disclosed.
From the tool's definition Tool name and description indicate 'Get the current editor viewport camera location and rotation' — a pure query operation that retrieves state without modifying or executing anything.
Attacks that exploit this kind of access
Get the current editor viewport camera location and rotation. It is categorised as a Read tool in the Unreal MCP Server, which means it retrieves data without modifying state.
Register the Unreal MCP server in PolicyLayer and add a rule for get_viewport_camera: 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 Unreal. Nothing to install.
get_viewport_camera 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_viewport_camera 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_viewport_camera. 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_viewport_camera is provided by the Unreal MCP server (sam-david/unreal-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
