WHAT IT DOES

What layer_show does on AutoCAD MCP Pro

AI agents use layer_show to create or update resources in AutoCAD MCP Pro, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AutoCAD MCP Pro environment.

RISK

Why layer_show is rated Medium

This tool modifies the visibility state of a layer in a CAD drawing, which is a reversible write operation. It does not delete data, execute arbitrary code, or have financial implications. The blast radius is low since it only toggles layer visibility, which can easily be undone.

RECOMMENDED RULE

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

layer_show Rate-limited

layer_show 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.

FAQ

Questions about layer_show

What does the layer_show tool do? +

How do I enforce a policy on layer_show? +

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

layer_show is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit layer_show? +

Yes. Add a rate_limit block to the layer_show 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_show completely? +

Set action: deny in the PolicyLayer policy for layer_show. 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_show? +

layer_show 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.
