WHAT IT DOES

What blender.capture_viewport does on CoWork OS

AI agents call blender.capture_viewport to retrieve information from CoWork OS without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why blender.capture_viewport is rated Low

Capturing a viewport is a read-only operation: it takes a screenshot/snapshot of the current 3D view. No data is created, modified, or deleted. The blast radius if misused is minimal — at most it exposes visual information about the current Blender scene.

From the tool's definition "Capture the current Blender viewport" — reads/snapshots the current visual state of the Blender viewport without modifying any data

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs blender.capture_viewport safely

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

blender.capture_viewport Allowed

blender.capture_viewport is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "blender.capture_viewport": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect CoWork OS, apply this rule, and every blender.capture_viewport call is checked against it from then on.
