AI agents call getObject 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 object properties from a 3D scene without creating, modifying, deleting, or executing any operations. It is a straightforward query operation with no blast radius if misused by an AI agent—at worst, it would return existing property data. This is clearly a Read operation.
From the tool's definition Tool name 'getObject' and description 'Get properties of a single scene object by id' indicate data retrieval with no modification or side effects.
Attacks that exploit this kind of access
Get properties of a single scene object by id. 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 getObject: 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.
getObject 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 getObject 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 getObject. 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.
getObject 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.
