AI agents call delete_entities_by_type to permanently remove resources in AutoCAD MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

While the blast radius is scoped to a single drawing file (not system-wide or financial), the destructive nature and inability to undo makes this the most severe category.

From the tool's definition Tool name 'delete_entities_by_type' combined with sibling tool 'delete_all_entities' and the verb 'Delete all entities' in the description. The tool irreversibly removes data from AutoCAD drawings.

Documented attack patterns abuse exactly the kind of access delete_entities_by_type gives an agent:

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_entities_by_type:

policy.json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_entities_by_type"
  ]
}

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

  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
