WHAT IT DOES

What layer_unlock does on AutoCAD MCP Pro

AI agents use layer_unlock to create or update resources in AutoCAD MCP Pro, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AutoCAD MCP Pro environment.

RISK

Why layer_unlock is rated Medium

Unlocking a layer changes its state to permit entity selection and modification, which is a reversible Write operation. While it enables further changes, the unlock itself is not destructive (the layer can be re-locked) and doesn't directly delete or execute arbitrary code.

From the tool's definition Tool name 'layer_unlock' and description 'Unlock a layer to allow entity selection and modification' indicate the tool modifies layer properties (lock status) to enable subsequent modifications.

RECOMMENDED RULE

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

layer_unlock Rate-limited

layer_unlock stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
