What delete_layer does on Pypi:best Cad
AI agents call delete_layer to permanently remove resources in Pypi:best Cad, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why delete_layer is rated Critical
This tool permanently removes layers from AutoCAD drawings. While the description notes restrictions (cannot delete current layer, layer 0, or layers with entities), the core function is destructive data removal. Layer deletion in CAD systems irreversibly alters the document structure.
From the tool's definition Tool name: delete_layer. Description indicates it deletes layers (删除图层 = 'delete layer'). The operation is irreversible—deleted layers and their associated data cannot be recovered in AutoCAD without undo, and once a drawing is saved, the deletion is…
Attacks that exploit this kind of access
The rule that runs delete_layer safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Pypi:best Cad, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For delete_layer, this is the rule to start with:
delete_layer 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 Pypi:best Cad, apply this rule, and every delete_layer call is checked against it from then on.
Questions about delete_layer

Register the Pypi:best Cad MCP server in PolicyLayer and add a rule for delete_layer: 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 Pypi:best Cad. Nothing to install.
delete_layer 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 delete_layer 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 delete_layer. 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.
delete_layer is provided by the Pypi:best Cad MCP server (pypi:best-cad-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
