WHAT IT DOES

What set_collection_visibility does on Blender Copilot MCP Server

AI agents use set_collection_visibility 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 set_collection_visibility is rated Medium

This tool changes visibility properties of collections and objects in Blender, which is a write operation that modifies scene state. The change is reversible (visibility can be toggled back), so it does not qualify as Destructive. The blast radius is medium because incorrect visibility changes could hide critical scene elements, affecting the user's workflow, but the change is easily undone.

From the tool's definition The tool description states it 'Set[s] viewport and render visibility of a collection and all its objects.' This modifies the visibility state of objects in a Blender scene, which is a reversible change to scene properties rather than permanent data deletion.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

set_collection_visibility Rate-limited

set_collection_visibility 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.
