WHAT IT DOES

What extrude_faces does on Blender Copilot MCP Server

AI agents use extrude_faces 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 extrude_faces is rated Medium

This tool modifies mesh geometry by extruding faces, which is a reversible write/modify operation on 3D model data. It does not delete data, execute arbitrary code, or involve financial transactions.

RECOMMENDED RULE

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

extrude_faces Rate-limited

extrude_faces 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.
