AI agents use create_document 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.
Creating a document is a reversible write operation. It generates new data but does not execute arbitrary code, delete existing data, or cause financial transactions. The tool modifies the FreeCAD workspace state by adding a new document artifact. Severity is low because the operation is isolated to document creation with no cascade effects on existing data or external systems.
From the tool's definition Tool description states 'Create a new FreeCAD document' and returns 'created document information' including name, label, and path. This creates new data (a document) reversibly within FreeCAD's in-memory state or file system.
Documented attack patterns abuse exactly the kind of access create_document 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 create_document:
{
"version": "1",
"default": "deny",
"tools": {
"create_document": {
"limits": [
{
"counter": "create_document_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_document 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 new FreeCAD document. Args: name: Internal document name (no spaces allowed, will be sanitized). label: Display label (can contain spaces). Defaults to name. Returns: Dictionary with created document information: - name: Internal document name - label: Display label - path: File path (None for new document). 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 create_document: 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.
create_document 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 create_document 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 create_document. 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.
create_document 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.
