WHAT IT DOES

What modifier_add does on Blender Copilot MCP Server

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

RISK

Why modifier_add is rated Medium

Based on the name alone, 'modifier_add' likely creates/adds a modifier to a Blender object, which is a reversible Write operation. Confidence is lowered due to the empty description. Severity is medium as misuse could alter 3D objects but is generally reversible.

From the tool's definition Tool name 'modifier_add' suggests adding a modifier to an object in Blender; description is empty and uninformative.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

modifier_add Rate-limited

modifier_add 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.
