AI agents use edit_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.
The tool creates or modifies data reversibly by editing object properties in FreeCAD. While it changes existing objects, the changes are not permanent or irreversible—properties can be edited again or undone.
From the tool's definition edit_object modifies properties of existing FreeCAD objects by accepting 'properties: Dictionary of property names and new values' and returning 'updated object information'.
Documented attack patterns abuse exactly the kind of access edit_object 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 edit_object:
{
"version": "1",
"default": "deny",
"tools": {
"edit_object": {
"limits": [
{
"counter": "edit_object_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}edit_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.

Edit properties of an existing FreeCAD object. Args: object_name: Name of the object to edit. properties: Dictionary of property names and new values. doc_name: Document containing the object. Uses active document if None. Returns: Dictionary with updated object information: - name: Object name - label: Object label - type_id: Object type. 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 edit_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.
edit_object 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 edit_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.
Set action: deny in the PolicyLayer policy for edit_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.
edit_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.
