WHAT IT DOES

What layer_list does on AutoCAD MCP Pro

AI agents call layer_list to retrieve information from AutoCAD MCP Pro without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why layer_list is rated Low

This tool performs a passive query of CAD layer metadata. It retrieves information about existing layers and their properties but does not create, modify, delete, or execute any actions. The blast radius of misuse is minimal—an agent cannot cause harm by listing layers. This is a classic Read operation: search/list/fetch with no side effects.

From the tool's definition Tool name 'layer_list' and description explicitly state it 'List all layers with their properties (color, linetype, frozen, locked, visibility)' — a read-only query operation that retrieves and displays layer metadata without modification.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs layer_list 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 layer_list, this is the rule to start with:

layer_list Allowed

layer_list is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "layer_list": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect AutoCAD MCP Pro, apply this rule, and every layer_list call is checked against it from then on.

FAQ

Questions about layer_list

What does the layer_list tool do? +

List all layers with their properties (color, linetype, frozen, locked, visibility). It is categorised as a Read tool in the AutoCAD MCP Pro MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on layer_list? +

Register the AutoCAD MCP Pro MCP server in PolicyLayer and add a rule for layer_list: 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 layer_list? +

layer_list is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit layer_list? +

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

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

What MCP server provides layer_list? +

layer_list 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.
