WHAT IT DOES

What blender_modifiers does on Blender

AI agents use blender_modifiers 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_modifiers is rated Medium

Blender modifiers are non-destructive operations applied to 3D objects (e.g., Subdivision Surface, Boolean, Array). Based on the tool name and server context, this tool likely adds, configures, or manages modifiers on Blender objects. Modifiers in Blender are generally reversible/non-destructive, placing this in the Write category. Confidence is low due to the empty description.

From the tool's definition Tool name 'blender_modifiers' combined with server description mentioning 'create, manipulate, and automate 3D scenes, objects, materials'

RECOMMENDED RULE

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

blender_modifiers Rate-limited

blender_modifiers 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_modifiers call is checked against it from then on.
