Create a new material in Cinema 4D. Args: name: Name for the new material color: Optional [R, G, B] color (values 0-1) properties: Optional additional material properties
AI agents use create_material to create or update resources in Cinema4D MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Cinema4D MCP Server environment.
This tool creates new scene data (materials) that persists in the project file. It is reversible (materials can be deleted), so it qualifies as Write rather than Destructive. The impact is medium severity because while it modifies project state, material creation alone does not directly cause rendering, financial loss, or execute arbitrary commands.
From the tool's definition Tool description states 'Create a new material in Cinema 4D' with parameters for name, color, and properties. The verb 'create' and the function signature indicate this adds a new material asset to a Cinema 4D project.
Documented attack patterns abuse exactly the kind of access create_material gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Cinema4D MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_material:
{
"version": "1",
"default": "deny",
"tools": {
"create_material": {
"limits": [
{
"counter": "create_material_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_material 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.

Create a new material in Cinema 4D. Args: name: Name for the new material color: Optional [R, G, B] color (values 0-1) properties: Optional additional material properties. It is categorised as a Write tool in the Cinema4D MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Cinema4D MCP Server MCP server in PolicyLayer and add a rule for 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 Cinema4D MCP Server. Nothing to install.
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 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 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.
create_material is provided by the Cinema4D MCP Server MCP server (ttiimmaacc/cinema4d-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
