AI agents use make_wire 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.
This tool creates new 3D modeling objects (wires/polylines) in FreeCAD, which is a reversible Write operation. It does not execute arbitrary code, delete data, or cause financial impact. The creation of geometric primitives is a standard modeling operation. Severity is low because misuse would only result in unwanted 3D objects that can be easily deleted or undone in FreeCAD.
From the tool's definition Tool description states it will "Create a wire (polyline) from a list of points" and returns created object information including name, label, type_id, and length.
Documented attack patterns abuse exactly the kind of access make_wire gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and FreeCAD Robust MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for make_wire:
{
"version": "1",
"default": "deny",
"tools": {
"make_wire": {
"limits": [
{
"counter": "make_wire_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}make_wire 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.

Create a wire (polyline) from a list of points. Args: points: List of points, each as [x, y, z]. closed: Whether to close the wire. Defaults to False. name: Object name. Auto-generated if None. doc_name: Target document. Uses active document if None. Returns: Dictionary with created object information: - name: Object name - label: Object label - type_id: Object type - length: Wire length. 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.
Register the FreeCAD Robust MCP Server MCP server in PolicyLayer and add a rule for make_wire: 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.
make_wire is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the make_wire 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 make_wire. 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.
make_wire 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.
