WHAT IT DOES

What close_document does on FreeCAD Robust MCP Server

AI agents call close_document 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 close_document is rated Critical

Closing a document in a CAD application like FreeCAD typically discards unsaved changes and removes the document from the workspace, which can be irreversible if unsaved work is lost. The name suggests a destructive action (potential data loss), but the empty description lowers confidence.

From the tool's definition Tool name 'close_document' — description is empty and uninformative.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs close_document safely

close_document Hidden
