What scale_object does on FreeCAD Robust MCP Server
AI agents invoke scale_object to trigger actions in FreeCAD Robust MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why scale_object is rated High
Although the description is empty (lowering confidence slightly), the tool name and context indicate it performs a geometric transformation operation on FreeCAD objects. This is an Execute rather than Write because scaling effects compound in design workflows and cannot be trivially undone without explicit undo actions—the operation triggers external FreeCAD state changes.
From the tool's definition Tool name 'scale_object' is in a FreeCAD 3D modeling context alongside geometry modification tools (add_sketch_arc, add_sketch_line, add_sketch_circle, etc.).
Attacks that exploit this kind of access
The rule that runs scale_object 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 scale_object, this is the rule to start with:
scale_object stays usable, but rate-capped: a runaway agent can't fire it dozens of times 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 scale_object call is checked against it from then on.
Questions about scale_object
scale_object is a execute tool on the FreeCAD Robust MCP Server MCP server. It is categorised as a Execute tool in the FreeCAD Robust MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the FreeCAD Robust MCP Server MCP server in PolicyLayer and add a rule for scale_object: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches FreeCAD Robust MCP Server. Nothing to install.
scale_object is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the scale_object rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for scale_object. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
scale_object is provided by the FreeCAD Robust MCP Server MCP server (spkane/freecad-addon-robust-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
