WHAT IT DOES

What mirror_object does on FreeCAD Robust MCP Server

AI agents use mirror_object 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 mirror_object is rated Medium

Mirroring is a reversible geometric transformation that modifies the 3D model state. It does not execute arbitrary code, delete data, or cause financial impact. The empty description reduces confidence slightly, but the context of FreeCAD modeling tools and the 'mirror_object' name clearly indicate a Write-class operation that transforms geometry without permanent destruction.

From the tool's definition Tool named 'mirror_object' in a FreeCAD 3D modeling context. Sibling tools (add_sketch_*, add_external_geometry) show this server manipulates 3D model geometry. Mirroring creates new or modifies existing objects in the model.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

mirror_object Rate-limited

mirror_object 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 mirror_object call is checked against it from then on.

FAQ

Questions about mirror_object

What does the mirror_object tool do? +

mirror_object is a write tool on the FreeCAD Robust MCP Server MCP server. It is categorised as a Write tool in the FreeCAD Robust MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on mirror_object? +

Register the FreeCAD Robust MCP Server MCP server in PolicyLayer and add a rule for mirror_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.

What risk level is mirror_object? +

mirror_object is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit mirror_object? +

Yes. Add a rate_limit block to the mirror_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.

How do I block mirror_object completely? +

Set action: deny in the PolicyLayer policy for mirror_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.

What MCP server provides mirror_object? +

mirror_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.
