List all objects in the current Cinema 4D scene. If this tool returns a validation error, use execute_python_script as a fallback to traverse the object hierarchy manually via the c4d API.
AI agents call list_objects to retrieve information from Cinema4D MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates existing scene data without creating, modifying, deleting, or executing any operations. It is a straightforward read-only query, making it low-risk. The mention of a fallback to execute_python_script is noted, but the tool itself performs only listing/enumeration.
From the tool's definition Tool name is 'list_objects' and description states 'List all objects in the current Cinema 4D scene' — a pure query operation with no modifications or side effects.
Documented attack patterns abuse exactly the kind of access list_objects 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 list_objects:
{
"version": "1",
"default": "deny",
"tools": {
"list_objects": {}
}
}list_objects is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all objects in the current Cinema 4D scene. If this tool returns a validation error, use execute_python_script as a fallback to traverse the object hierarchy manually via the c4d API. It is categorised as a Read tool in the Cinema4D MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Cinema4D MCP Server MCP server in PolicyLayer and add a rule for list_objects: 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.
list_objects is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_objects 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 list_objects. 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.
list_objects 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.
