THE RISK

Medium Risk

Why freecad_move_object needs a policy

This tool modifies the position of an existing object in FreeCAD by updating its coordinates. It's a reversible modification (the object can be moved back), so it falls under Write rather than Destructive. Misuse could displace design elements in a CAD model, potentially corrupting designs if positions are set incorrectly.

From the tool's definition Move an object to a new absolute position. Specify at least one coordinate.

POLICY

How to control freecad_move_object

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_move_object:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "freecad_move_object": {
      "limits": [
        {
          "counter": "freecad_move_object_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

freecad_move_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.

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_move_object

What does the freecad_move_object tool do? +

Move an object to a new absolute position. Specify at least one coordinate. It is categorised as a Write tool in the Mcp Freecad MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on freecad_move_object? +

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

What risk level is freecad_move_object? +

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

Can I rate-limit freecad_move_object? +

Yes. Add a rate_limit block to the freecad_move_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 freecad_move_object completely? +

Set action: deny in the PolicyLayer policy for freecad_move_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 freecad_move_object? +

freecad_move_object 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.
