AI agents invoke entity_array_polar to trigger actions in AutoCAD MCP Pro. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
A polar array operation in CAD creates multiple copies of entities arranged in a circular pattern, which constitutes a write/execute operation modifying the drawing. Since the description is empty, confidence is reduced. The most likely behavior is creating new entities (Write), but array operations in CAD can also trigger complex operations.
From the tool's definition Tool name 'entity_array_polar' suggests creating a polar array of entities in AutoCAD; description is empty and uninformative.
Documented attack patterns abuse exactly the kind of access entity_array_polar gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and AutoCAD MCP Pro, and nothing reaches the server without passing your rules. This is the rule we recommend for entity_array_polar:
{
"version": "1",
"default": "deny",
"tools": {
"entity_array_polar": {
"limits": [
{
"counter": "entity_array_polar_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}entity_array_polar stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
Free to start. No card required.
entity_array_polar. It is categorised as a Execute tool in the AutoCAD MCP Pro MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the AutoCAD MCP Pro MCP server in PolicyLayer and add a rule for entity_array_polar: 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.
entity_array_polar is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the entity_array_polar 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 entity_array_polar. 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.
entity_array_polar is provided by the AutoCAD MCP Pro MCP server (u-c4n/autocad-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from AutoCAD MCP Pro, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
