Why freecad_boolean_cut needs a policy

A boolean cut is a geometric operation that modifies 3D objects by computing the difference between two shapes. It is a destructive modeling operation within FreeCAD, but since it operates on CAD objects in a design environment (not system files or data), it is best classified as Execute — it triggers an external operation (FreeCAD geometry computation) whose effects depend on the arguments provided.

From the tool's definition Perform a boolean cut (difference) between two objects (object1 - object2)

POLICY

How to control freecad_boolean_cut

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Freecad, and nothing reaches the server without passing your rules. This is the rule we recommend for freecad_boolean_cut:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "freecad_boolean_cut": {
      "limits": [
        {
          "counter": "freecad_boolean_cut_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

freecad_boolean_cut 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.

Create a free account and register Mcp Freecad — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about freecad_boolean_cut

What does the freecad_boolean_cut tool do? +

Perform a boolean cut (difference) between two objects (object1 - object2). It is categorised as a Execute tool in the Mcp Freecad MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on freecad_boolean_cut? +

Register the Mcp Freecad MCP server in PolicyLayer and add a rule for freecad_boolean_cut: 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 Mcp Freecad. Nothing to install.

What risk level is freecad_boolean_cut? +

freecad_boolean_cut is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit freecad_boolean_cut? +

Yes. Add a rate_limit block to the freecad_boolean_cut 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 freecad_boolean_cut completely? +

Set action: deny in the PolicyLayer policy for freecad_boolean_cut. 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 freecad_boolean_cut? +

freecad_boolean_cut is provided by the Mcp Freecad MCP server (jango-blockchained/mcp-freecad). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Mcp Freecad tool call.

Start from Mcp Freecad, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
