WHAT IT DOES

What create_line does on Aos

AI agents use create_line 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.

RISK

Why create_line is rated Medium

The tool creates new geometry in the Rhino 8 CAD environment, which is a reversible write operation. While CAD models can be important, individual geometry creation is not inherently destructive (can be undone via undo), not financial, and not code execution—it is a standard modeling operation.

From the tool's definition Tool description states 'Create a straight line curve.' The verb 'create' indicates data creation. The broader server context mentions 'create geometry' and 'execute arbitrary Python scripts', confirming this tool modifies the Rhino 3D model by adding new…

RECOMMENDED RULE

The rule that runs create_line 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 create_line, this is the rule to start with:

create_line Rate-limited

create_line 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.

FAQ

Questions about create_line

What does the create_line tool do? +

Create a straight line curve. 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.

How do I enforce a policy on create_line? +

Register the Aos MCP server in PolicyLayer and add a rule for create_line: 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.

What risk level is create_line? +

create_line is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_line? +

Yes. Add a rate_limit block to the create_line 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.

How do I block create_line completely? +

Set action: deny in the PolicyLayer policy for create_line. 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.

What MCP server provides create_line? +

create_line 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.
