What deleteMaterialLayer does on Spline MCP Server
AI agents call deleteMaterialLayer to permanently remove resources in Spline MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why deleteMaterialLayer is rated Critical
Any tool with 'delete' in its name that operates on design assets performs irreversible data removal. This ranks as Destructive rather than Write because deletion cannot be undone through normal operations. In a 3D design context, removing a material layer could destroy work that took time to create.
From the tool's definition Tool name 'deleteMaterialLayer' contains the verb 'delete', indicating irreversible removal of data. The tool description is empty, preventing confirmation of scope, but the function name strongly suggests permanent deletion of a material layer object in the…

The rule that runs deleteMaterialLayer safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Spline MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For deleteMaterialLayer, this is the rule to start with:
deleteMaterialLayer 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 Spline MCP Server, apply this rule, and every deleteMaterialLayer call is checked against it from then on.
