在AutoCAD中绘制圆 Args: center_x: 圆心X坐标 center_y: 圆心Y坐标 radius: 半径 layer: 可选的图层名称
AI agents use draw_circle to create or update resources in AutoCAD MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AutoCAD MCP Server environment.
This tool creates a new circle entity in an AutoCAD drawing. It is a Write operation because it adds/modifies drawing content in a reversible way (the circle can be deleted). It does not execute code, destroy data, or involve financial transactions. Severity is medium because misuse could corrupt or pollute a drawing, but effects are recoverable.
From the tool's definition 绘制圆 (draw circle) with parameters for center coordinates, radius, and optional layer — creates a new geometric entity in the AutoCAD drawing
Documented attack patterns abuse exactly the kind of access draw_circle gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and AutoCAD MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for draw_circle:
{
"version": "1",
"default": "deny",
"tools": {
"draw_circle": {
"limits": [
{
"counter": "draw_circle_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}draw_circle 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.

在AutoCAD中绘制圆 Args: center_x: 圆心X坐标 center_y: 圆心Y坐标 radius: 半径 layer: 可选的图层名称. It is categorised as a Write tool in the AutoCAD MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the AutoCAD MCP Server MCP server in PolicyLayer and add a rule for draw_circle: 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 Server. Nothing to install.
draw_circle 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 draw_circle 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 draw_circle. 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.
draw_circle is provided by the AutoCAD MCP Server MCP server (zh19980811/easy-mcp-autocad). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
