Add soft body dynamics to the specified object. Args: object_name: Name of the object to convert to a soft body
AI agents use create_soft_body 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 modifies an existing 3D object in Cinema 4D by attaching soft body dynamics to it. This is a reversible modification (the dynamics tag can be removed), placing it in the Write category. Misuse could corrupt scene objects or cause unintended simulation behavior, warranting medium severity.
From the tool's definition 'Add soft body dynamics to the specified object' — modifies an existing object by applying a dynamics simulation tag/property to it
Documented attack patterns abuse exactly the kind of access create_soft_body 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_soft_body:
{
"version": "1",
"default": "deny",
"tools": {
"create_soft_body": {
"limits": [
{
"counter": "create_soft_body_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_soft_body 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 soft body dynamics to the specified object. Args: object_name: Name of the object to convert to a soft body. 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_soft_body: 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_soft_body 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_soft_body 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_soft_body. 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_soft_body 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.
