Add a MoGraph Effector to the scene. Args: effector_type: Type of effector (random, shader, field) name: Optional name for the effector target: Optional target object (e.g., cloner) to apply the effector to
AI agents use add_effector 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 MoGraph Effector objects in a Cinema 4D scene, modifying the scene structure. This is a Write-category action because it adds new data/objects to the scene. Severity is medium because misuse could clutter a scene with unwanted effectors, but the effects are fully reversible by deleting the added objects.
From the tool's definition Tool description states 'Add a MoGraph Effector to the scene' with parameters for effector_type, name, and target object. The verb 'Add' indicates creation of new scene elements, which is reversible through deletion.
Documented attack patterns abuse exactly the kind of access add_effector 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 add_effector:
{
"version": "1",
"default": "deny",
"tools": {
"add_effector": {
"limits": [
{
"counter": "add_effector_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}add_effector 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.

Add a MoGraph Effector to the scene. Args: effector_type: Type of effector (random, shader, field) name: Optional name for the effector target: Optional target object (e.g., cloner) to apply the effector to. 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 add_effector: 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.
add_effector 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 add_effector 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 add_effector. 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.
add_effector 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.
