Create PBR material with Principled BSDF shader. Creates material with standard PBR properties. Use Principled BSDF workflow. Args: - material_name: Material name - base_color (optional): RGBA [r, g, b, a] with 0-1 values - metallic (optional): 0-1, default 0 - roughness (optional): 0-1, default ...
AI agents use blender_create_material to create or update resources in ClaudeKit Blender MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ClaudeKit Blender MCP environment.
This tool creates and modifies material data within Blender, which is a reversible operation. It does not execute arbitrary code (that would be blender_execute_code), does not delete anything (that would be blender_delete_object), and does not retrieve data. Material creation is a write operation that can be undone in Blender.
From the tool's definition The tool creates PBR material with Principled BSDF shader and accepts parameters like material_name, base_color, metallic, roughness, and emission properties. It returns a success message indicating material creation/modification in the Blender scene.

Create PBR material with Principled BSDF shader. Creates material with standard PBR properties. Use Principled BSDF workflow. Args: - material_name: Material name - base_color (optional): RGBA [r, g, b, a] with 0-1 values - metallic (optional): 0-1, default 0 - roughness (optional): 0-1, default 0.5 - emission_color (optional): RGBA for emission - emission_strength (optional): Emission intensity Returns: Success message Example: { material_name:. It is categorised as a Write tool in the ClaudeKit Blender MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the ClaudeKit Blender MCP server in PolicyLayer and add a rule for blender_create_material: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches ClaudeKit Blender MCP. Nothing to install.
blender_create_material is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the blender_create_material rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for blender_create_material. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
blender_create_material is provided by the ClaudeKit Blender MCP server (olbboy/claudekit-blender-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
