WHAT IT DOES

What vrc_rename_bones does on Blender Copilot MCP Server

AI agents use vrc_rename_bones 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 vrc_rename_bones is rated Medium

Renaming bones is a write operation—it modifies model structure reversibly. While not destructive, it could cause issues if an AI agent renames bones incorrectly, breaking rigging, animations, or VRChat avatar compatibility.

From the tool's definition The tool description states it 'Rename bones from common naming schemes', which modifies existing bone naming data in the 3D model without deleting them. This is a reversible change to model metadata.
