WHAT IT DOES

What construction_clear does on AutoCAD MCP Pro

AI agents call construction_clear 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.

RISK

Why construction_clear is rated Critical

This tool irreversibly removes all entities from a specified layer, destroying data that cannot be recovered without undo. While scoped to the CONSTRUCTION layer, the operation is permanent and affects all objects on that layer simultaneously. This is a destructive action (delete operation) rather than merely a write or execute operation, placing it in the Destructive category.

From the tool's definition Delete every entity on the CONSTRUCTION layer.

RECOMMENDED RULE

The rule that runs construction_clear 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 construction_clear, this is the rule to start with:

construction_clear Hidden

construction_clear is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
