WHAT IT DOES

What list_vm_skeletons does on Ludus FastMCP

AI agents call list_vm_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.

RISK

Why list_vm_skeletons is rated Low

The verb 'list' is a classic Read operation that retrieves and displays data without side effects. Although the description is empty (which reduces confidence slightly), the naming convention and the context of a cyber range management system where VM skeletons are template/configuration objects to be queried make it clear this is a data retrieval tool. No creation, modification, deletion, or execution is implied.

From the tool's definition Tool name 'list_vm_skeletons' indicates a listing/retrieval operation with no modification capability. The 'list_' prefix strongly suggests a query that retrieves existing VM skeleton data.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_vm_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_vm_skeletons, this is the rule to start with:

list_vm_skeletons Allowed

list_vm_skeletons is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Ludus FastMCP, apply this rule, and every list_vm_skeletons call is checked against it from then on.
