WHAT IT DOES

What export_obj does on FreeCAD Robust MCP Server

AI agents use export_obj 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 export_obj is rated Medium

Export functions create new files or data artifacts on the user's system, which is a Write operation (reversible data creation). Severity is medium because exported files can be saved to disk, potentially overwriting existing files or consuming storage, but the action is reversible (files can be deleted).

From the tool's definition Tool name 'export_obj' indicates exporting 3D model data to OBJ format. FreeCAD context shows tools for creating and modifying 3D geometry. Export operations create output files.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

export_obj Rate-limited

export_obj 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.
