WHAT IT DOES

What delete_sketch_geometry does on FreeCAD Robust MCP Server

AI agents call delete_sketch_geometry to permanently remove resources in FreeCAD Robust MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why delete_sketch_geometry is rated Critical

The 'delete_' prefix indicates this tool performs irreversible data destruction. In the context of FreeCAD 3D modeling, deleting sketch geometry cannot be undone programmatically through this tool and represents a destructive operation on the model. While the description is empty, the name itself provides sufficient evidence for this classification.

From the tool's definition Tool name 'delete_sketch_geometry' explicitly contains 'delete', indicating irreversible removal of sketch geometry objects in FreeCAD.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs delete_sketch_geometry 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 delete_sketch_geometry, this is the rule to start with:

delete_sketch_geometry Hidden

delete_sketch_geometry is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
