WHAT IT DOES

What entity_create_ellipse does on AutoCAD MCP Pro

AI agents use entity_create_ellipse to create or update resources in AutoCAD MCP Pro, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AutoCAD MCP Pro environment.

RISK

Why entity_create_ellipse is rated Medium

Creating a CAD entity is a reversible write operation that modifies the drawing state. Severity is medium because an agent could be misled into creating incorrect geometry affecting engineering designs, but changes can be undone via undo/revision. Confidence is 0.75 due to missing description, but the 'create' prefix in the name and server context (drawing creation capability) strongly indicate Write classification.

From the tool's definition Tool name 'entity_create_ellipse' indicates creation of a new ellipse entity in AutoCAD; no description provided.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs entity_create_ellipse safely

PolicyLayer is an MCP gateway: it sits between your AI agents and AutoCAD MCP Pro, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For entity_create_ellipse, this is the rule to start with:

entity_create_ellipse Rate-limited

entity_create_ellipse 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.

How do I enforce a policy on entity_create_ellipse? +

Register the AutoCAD MCP Pro MCP server in PolicyLayer and add a rule for entity_create_ellipse: 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 AutoCAD MCP Pro. Nothing to install.

What risk level is entity_create_ellipse? +

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

Can I rate-limit entity_create_ellipse? +

Yes. Add a rate_limit block to the entity_create_ellipse 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 entity_create_ellipse completely? +

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