WHAT IT DOES

What blender_mesh does on Blender

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

RISK

Why blender_mesh is rated Medium

From the tool's definition Tool name 'blender_mesh' on a server for controlling Blender to create, manipulate, and automate 3D scenes and objects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs blender_mesh safely

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

blender_mesh Rate-limited

blender_mesh 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 Blender, apply this rule, and every blender_mesh call is checked against it from then on.
