WHAT IT DOES

What add_bone does on Blend Ai

AI agents use add_bone to create or update resources in Blend Ai, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Blend Ai environment.

RISK

Why add_bone is rated Medium

Adding a bone to an armature in Blender creates new skeletal structure data that modifies the project but does not irreversibly delete data or execute arbitrary code. This is a reversible write operation typical of 3D modeling creation tools. Severity is medium because misuse could corrupt model rigging and require rework, but damage is contained to the current project and reversible.

From the tool's definition Tool name 'add_bone' indicates creation of skeletal structure elements in Blender. Sibling tools like 'add_constraint', 'add_modifier', 'add_particle_system' all perform creation/modification operations.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs add_bone safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Blend Ai, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For add_bone, this is the rule to start with:

add_bone Rate-limited

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.

The button opens the PolicyLayer dashboard: create your workspace, connect Blend Ai, apply this rule, and every add_bone call is checked against it from then on.
