WHAT IT DOES

What list_user_sessions does on CloudStack MCP Server

AI agents call list_user_sessions to retrieve information from CloudStack MCP Server 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_user_sessions is rated Low

While this is categorized as Read (no data modification), the severity is elevated to high because user session data is highly sensitive security information. Unauthorized enumeration of active sessions could enable targeted account takeover, privilege escalation, or session hijacking attacks.

From the tool's definition list_user_sessions retrieves active user session data, which is a read-only query operation without side effects. The description states it 'List active user sessions' — a retrieval function.

RECOMMENDED RULE

The rule that runs list_user_sessions safely

PolicyLayer is an MCP gateway: it sits between your AI agents and CloudStack MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_user_sessions, this is the rule to start with:

list_user_sessions Allowed

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

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_user_sessions": {}
  }
}

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

The button opens the PolicyLayer dashboard: create your workspace, connect CloudStack MCP Server, apply this rule, and every list_user_sessions call is checked against it from then on.
