WHAT IT DOES

What set_object_color does on FreeCAD Robust MCP Server

AI agents use set_object_color 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 set_object_color is rated Medium

This tool modifies object attributes in FreeCAD (setting color), which is a reversible write operation. It changes the state of a 3D model but does not delete data or execute arbitrary code. Severity is medium because color changes could affect model visualization and workflow, but the impact is non-destructive and localized to visual properties.

From the tool's definition Tool name 'set_object_color' indicates modification of an object's visual property (color). The description is empty, limiting direct evidence from documentation.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

set_object_color Rate-limited

set_object_color 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.

The button opens the PolicyLayer dashboard: create your workspace, connect FreeCAD Robust MCP Server, apply this rule, and every set_object_color call is checked against it from then on.
