WHAT IT DOES

What material_list_presets does on Blender Copilot MCP Server

AI agents call material_list_presets to retrieve information from Blender Copilot MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why material_list_presets is rated Low

The tool only lists/reads existing material presets and their descriptions. It performs no modifications, deletions, or executions. Blast radius if misused is negligible.

From the tool's definition 'List all material presets with descriptions' — pure retrieval, no side effects

RECOMMENDED RULE

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

material_list_presets Allowed

material_list_presets 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": {
    "material_list_presets": {}
  }
}

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

The button opens the PolicyLayer dashboard: create your workspace, connect Blender Copilot MCP Server, apply this rule, and every material_list_presets call is checked against it from then on.
