Rotate an object around an axis. Modifies the object's placement in-place. Args: object_name: Name of the object to rotate. axis: Rotation axis as [x, y, z] vector. angle: Rotation angle in degrees. center: Center point for rotation [x, y, z]. Uses object center if None. doc_name: Document contai...
AI agents use rotate_object to create or update resources in FreeCAD Robust MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your FreeCAD Robust MCP Server environment.
This tool modifies 3D model data reversibly by changing an object's rotation and placement properties. It is a Write operation because the modification can be undone (FreeCAD supports undo/redo), and it does not delete data or execute arbitrary code. Severity is medium because misuse could corrupt a user's 3D model file, but the damage is reversible and limited to geometric transformation of a single object.
From the tool's definition Tool description states it 'Modifies the object's placement in-place' and returns 'new placement' with position and rotation values. The tool transforms object geometry by rotating it around a specified axis by a given angle.
Documented attack patterns abuse exactly the kind of access rotate_object gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and FreeCAD Robust MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for rotate_object:
{
"version": "1",
"default": "deny",
"tools": {
"rotate_object": {
"limits": [
{
"counter": "rotate_object_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}rotate_object 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.

Rotate an object around an axis. Modifies the object's placement in-place. Args: object_name: Name of the object to rotate. axis: Rotation axis as [x, y, z] vector. angle: Rotation angle in degrees. center: Center point for rotation [x, y, z]. Uses object center if None. doc_name: Document containing the object. Uses active document if None. Returns: Dictionary with new placement: - position: New position [x, y, z] - rotation: New rotation angles. It is categorised as a Write tool in the FreeCAD Robust MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the FreeCAD Robust MCP Server MCP server in PolicyLayer and add a rule for rotate_object: 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 FreeCAD Robust MCP Server. Nothing to install.
rotate_object 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 rotate_object 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 rotate_object. 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.
rotate_object is provided by the FreeCAD Robust MCP Server MCP server (spkane/freecad-addon-robust-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
