## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "create_partdesign_body",
    "arguments": {}
  }
}
```

## Why create_partdesign_body is rated Medium

Creating a PartDesign Body is a Write operation—it adds a new modeling container to the FreeCAD document. While reversible (can be deleted/undone), it modifies the document state. Severity is medium because misuse could create unwanted geometry or consume resources, but effects are contained within the design file and easily undoable.

From the tool's own definition: "Tool named 'create_partdesign_body' in FreeCAD context; creates a new PartDesign Body object. This is a reversible data creation operation within a 3D modeling document."

## Use case

AI agents use create_partdesign_body 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.

## Recommended policy (PolicyLayer)
