AI agents call listScenes to retrieve information from Maige 3d without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays metadata about saved 3D scenes without modifying, deleting, or executing any operations. It is a straightforward read operation that returns a list of available resources, making it the lowest-risk category.
From the tool's definition The tool name 'listScenes' and description 'List all saved scene JSON files in the scenes/ folder' indicate a query/retrieval operation with no side effects.
Attacks that exploit this kind of access
List all saved scene JSON files in the scenes/ folder. It is categorised as a Read tool in the Maige 3d MCP Server, which means it retrieves data without modifying state.
Register the Maige 3d MCP server in PolicyLayer and add a rule for listScenes: 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 Maige 3d. Nothing to install.
listScenes 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 listScenes 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 listScenes. 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.
listScenes is provided by the Maige 3d MCP server (m-ai-gexr/mcp-webgpu). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
