WHAT IT DOES

What insert_part_from_library does on FreeCAD Robust MCP Server

RISK

Why insert_part_from_library is rated Medium

The tool performs a reversible creation/insertion operation within a 3D modeling project—consistent with Write category. It does not execute arbitrary code, delete data, or move money. Severity is medium because inserting parts into an active design could have moderate impact on a user's model, but the action is undoable in FreeCAD.

From the tool's definition Tool name 'insert_part_from_library' indicates it adds/inserts a part into a FreeCAD design. Description is empty, limiting direct confirmation.
