What loft_curves does on Aos
AI agents use loft_curves 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 loft_curves is rated Medium
Lofting curves is a geometry creation operation in CAD software — it generates a surface through a series of curves. This creates/modifies data in the Rhino scene, making it a Write operation. Confidence is reduced because the description is empty; classification is based on the tool name and server context alone.
From the tool's definition Tool name 'loft_curves' combined with server context: creates geometry in Rhino 8 by lofting curves into surfaces
Attacks that exploit this kind of access
The rule that runs loft_curves 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 loft_curves, this is the rule to start with:
loft_curves 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 loft_curves call is checked against it from then on.
Questions about loft_curves
loft_curves is a write tool on the Aos MCP server. 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 loft_curves: 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.
loft_curves 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 loft_curves 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 loft_curves. 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.
loft_curves 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.
