What copy_objects does on Aos
AI agents use copy_objects to create or update resources in Aos, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Aos environment.
Why copy_objects is rated Medium
Copying and translating objects creates new data in the design model but does not destroy or permanently alter existing geometry. The action is reversible (copies can be deleted). While the broader server context includes destructive booleans and arbitrary Python execution (more severe), this specific tool performs a Write operation that modifies the model state by adding new objects.
From the tool's definition Tool description states 'Copy objects and translate the copies' — this creates new geometry objects in the Rhino model, a reversible modification.
Attacks that exploit this kind of access
The rule that runs copy_objects safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Aos, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For copy_objects, this is the rule to start with:
copy_objects stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Aos, apply this rule, and every copy_objects call is checked against it from then on.
Questions about copy_objects
Copy objects and translate the copies by a displacement vector. It is categorised as a Write tool in the Aos MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Aos MCP server in PolicyLayer and add a rule for copy_objects: 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 Aos. Nothing to install.
copy_objects 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 copy_objects 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 copy_objects. 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.
copy_objects is provided by the Aos MCP server (@hybridlabor-api/aos). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
