WHAT IT DOES

What armature_add_bone does on Blender Copilot MCP Server

AI agents use armature_add_bone 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 armature_add_bone is rated Medium

The tool creates a new bone in a Blender armature structure, which is a reversible modification to the scene (bones can be deleted or modified). This is Write-class behavior. Severity is medium because misuse could corrupt a complex rigged character model, but the effect is confined to a single armature and remains fully reversible.

From the tool's definition Tool name 'armature_add_bone' indicates creation of a bone in a Blender armature. No description provided.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

armature_add_bone Rate-limited

armature_add_bone 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.
