WHAT IT DOES

What modifier_remove does on Blender Copilot MCP Server

AI agents call modifier_remove to permanently remove resources in Blender Copilot MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why modifier_remove is rated Critical

Removing a modifier without applying it is irreversible destruction of that modifier's configuration and effects — it cannot be undone once removed (outside of Blender's undo stack, which an AI agent may not reliably use). The modifier settings and stack position are permanently lost.

RECOMMENDED RULE

The rule that runs modifier_remove safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Blender Copilot MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For modifier_remove, this is the rule to start with:

modifier_remove Hidden

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