delete_last_entities

THE RISK

Critical Risk

This tool permanently removes data (AutoCAD entities) without the ability to undo via the MCP interface. While severity is not critical (limited to recent entities rather than arbitrary selection), the irreversible nature of deletion and potential for significant work loss in a design context justifies the Destructive category and high severity rating.

From the tool's definition Tool name includes "delete" and description states "Delete the last N entities created". The action is irreversible—deleted entities in AutoCAD cannot be recovered programmatically through this tool.

HOW TO CONTROL DELETE_LAST_ENTITIES

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 delete_last_entities:

policy.json

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

delete_last_entities 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 Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I enforce a policy on delete_last_entities? +

Register the AutoCAD MCP Server MCP server in PolicyLayer and add a rule for delete_last_entities: 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.

What risk level is delete_last_entities? +

delete_last_entities 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 delete_last_entities? +

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

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