WHAT IT DOES

What delete_object does on Freecad mcp

AI agents call delete_object to permanently remove resources in Freecad mcp — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

THE RISK

Critical Risk

Why delete_object needs a policy

This tool performs an irreversible deletion operation on FreeCAD objects. Once deleted, the object cannot be recovered unless the document is reverted or undo is used. The action destroys data and fits the Destructive category definition of 'irreversibly deletes or overwrites data, or actions that cannot be undone.' High severity is assigned because unintended deletion of CAD objects in an engineering document could…

From the tool's definition Tool name is 'delete_object' and description explicitly states 'Delete an object in FreeCAD.' The function removes objects irreversibly from FreeCAD documents.

POLICY

How to control delete_object

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

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_object"
  ]
}

delete_object disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Freecad mcp — 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 delete_object

What does the delete_object tool do? +

Delete an object in FreeCAD. Args: doc_name: The name of the document to delete the object from. obj_name: The name of the object to delete. Returns: A message indicating the success or failure of the object deletion and a screenshot of the object. It is categorised as a Destructive tool in the Freecad mcp MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.

How do I enforce a policy on delete_object? +

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

What risk level is delete_object? +

delete_object is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit delete_object? +

Yes. Add a rate_limit block to the delete_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 delete_object completely? +

Set action: deny in the PolicyLayer policy for delete_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 delete_object? +

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

Enforce policy on every Freecad mcp tool call.

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