THE RISK

Critical Risk

Why entity_delete_many needs a policy

Deletion operations fall under the Destructive category per the classification rules, as they irreversibly remove data without a built-in undo mechanism at the tool level. In a CAD context, deleting multiple entities could corrupt designs, remove critical architectural or engineering details, or destroy work products.

From the tool's definition Tool name 'entity_delete_many' explicitly performs deletion of multiple entities. Description states 'Delete multiple entities in one call' with no undo capability mentioned. This is an irreversible removal of CAD design elements from drawings.

POLICY

How to control entity_delete_many

PolicyLayer is an MCP gateway — it sits between your AI agents and AutoCAD MCP Pro, and nothing reaches the server without passing your rules. This is the rule we recommend for entity_delete_many:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "entity_delete_many"
  ]
}

entity_delete_many disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register AutoCAD MCP Pro — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about entity_delete_many

What does the entity_delete_many tool do? +

Delete multiple entities in one call. Returns count of deleted entities. It is categorised as a Destructive tool in the AutoCAD MCP Pro MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.

How do I enforce a policy on entity_delete_many? +

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

entity_delete_many is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit entity_delete_many? +

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

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

entity_delete_many 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.

Enforce policy on every AutoCAD MCP Pro tool call.

Start from AutoCAD MCP Pro, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
