[WIP] Computers with Most Sessions [Required: sessions]
AI agents call computers_with_most_sessions to retrieve information from BloodHound MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about which computers have the most active sessions. It is a read-only query operation that gathers intelligence about system activity in an Active Directory environment.

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