What entity_delete_many does on AutoCAD MCP Pro
AI agents call entity_delete_many to permanently remove resources in AutoCAD MCP Pro, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why entity_delete_many is rated Critical
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.
Attacks that exploit this kind of access
The rule that runs entity_delete_many 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 entity_delete_many, this is the rule to start with:
entity_delete_many is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect AutoCAD MCP Pro, apply this rule, and every entity_delete_many call is checked against it from then on.
Questions about entity_delete_many
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.
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.
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.
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.
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.
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.
