What list_range_skeletons does on Ludus FastMCP
AI agents call list_range_skeletons to retrieve information from Ludus FastMCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why list_range_skeletons is rated Low
The tool name strongly suggests it retrieves or enumerates range skeleton configurations without altering them. Despite the empty description, the semantic structure (list + noun) and context within a cyber range management system indicate this is a data retrieval operation with minimal blast radius. Low severity because it only exposes information about available templates or configurations.
From the tool's definition Tool name 'list_range_skeletons' indicates a listing/retrieval operation with no modification capability. The 'list_' prefix is a standard pattern for read-only queries.
Attacks that exploit this kind of access
The rule that runs list_range_skeletons safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Ludus FastMCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_range_skeletons, this is the rule to start with:
list_range_skeletons is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Ludus FastMCP, apply this rule, and every list_range_skeletons call is checked against it from then on.
