WHAT IT DOES

What linetype_list does on AutoCAD MCP Pro

AI agents call linetype_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 linetype_list is rated Low

linetype_list performs a read-only operation to enumerate linetype names from the current AutoCAD drawing. It retrieves information about existing drawing properties without creating, modifying, deleting, or executing any operations. No external effects or state changes result from calling this tool. This clearly fits the Read category as a data retrieval operation with minimal blast radius if misused by an AI agent.

From the tool's definition Tool description states 'Return the names of all linetypes currently loaded in the active drawing.' This is a query operation that retrieves and lists existing data without modification or side effects.

RECOMMENDED RULE

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

linetype_list Allowed

linetype_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": {
    "linetype_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 linetype_list call is checked against it from then on.
