AI agents use create_layer 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 or modifies layers, which are reversible structural elements in AutoCAD drawings. Layers can be deleted or their properties changed, so the operation is not destructive. It does not execute arbitrary code, does not involve financial transactions, and does not irreversibly delete data.
From the tool's definition Tool name 'create_layer' and description '创建或修改图层' (create or modify layer) directly indicate creation and modification of drawing layers in AutoCAD. The parameters (name, color_index) are used to define layer properties.
Documented attack patterns abuse exactly the kind of access create_layer 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 create_layer:
{
"version": "1",
"default": "deny",
"tools": {
"create_layer": {
"limits": [
{
"counter": "create_layer_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_layer 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.

创建或修改图层 Args: name: 图层名称 color_index: 颜色索引 (1-255). 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 create_layer: 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.
create_layer 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 create_layer 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 create_layer. 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.
create_layer 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.
