Export range backup. Args: include_vms: Include VM disk images in backup include_config: Include configuration in backup user_id: Optional user ID (admin only) Returns: Backup export result with download link
AI agents call export_range_backup to retrieve information from Ludus FastMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool creates a backup export and returns a download link, which is primarily a read/export operation (retrieving a snapshot of data). However, it may involve creating a new file/archive on the server, which could be considered a Write. The most accurate classification is Read since it doesn't modify the range itself—it packages existing data for download.

PolicyLayer is an MCP gateway — it sits between your AI agents and Ludus FastMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for export_range_backup:
{
"version": "1",
"default": "deny",
"tools": {
"export_range_backup": {}
}
}export_range_backup is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
