AI agents use copy_entity 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.
Copying an entity in AutoCAD creates new drawing objects but does not irreversibly delete or overwrite existing data. The operation is reversible (the copy can be deleted). This is a Write operation that modifies the drawing by adding new entities.
From the tool's definition Tool name 'copy_entity' and description indicating it copies an entity from a source handle to a target location (start_point to end_point). This creates a duplicate of existing drawing data.
Documented attack patterns abuse exactly the kind of access copy_entity 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 copy_entity:
{
"version": "1",
"default": "deny",
"tools": {
"copy_entity": {
"limits": [
{
"counter": "copy_entity_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}copy_entity 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.

复制实体 Args: handle: 源实体句柄 start_point: 基干点 [x, y, z] end_point: 目标点 [x, y, z]. 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 copy_entity: 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.
copy_entity 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 copy_entity 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 copy_entity. 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.
copy_entity 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.
