WHAT IT DOES

What copy_object does on FreeCAD Robust MCP Server

AI agents use copy_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.

RISK

Why copy_object is rated Medium

Copying an object in FreeCAD creates new data (a duplicate) reversibly; the operation can be undone and does not permanently destroy information. This qualifies as Write rather than Read (which merely retrieves) or Destructive (which irreversibly deletes). Severity is medium because misuse could clutter the model or consume resources, but effects are non-destructive and localized to the project file.

From the tool's definition Tool name 'copy_object' indicates creation of a duplicate of an existing 3D model object in FreeCAD. The description is empty, which lowers confidence, but the naming convention and context of a modeling server (alongside sibling tools like add_sketch_line,…

RECOMMENDED RULE

The rule that runs copy_object safely

PolicyLayer is an MCP gateway: it sits between your AI agents and FreeCAD Robust MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For copy_object, this is the rule to start with:

copy_object Rate-limited

copy_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.
