[WIP] List all principal(s) used for syncing AD and AAD
How to control list_all_principals_used_for_syncing_ad_and_aad ↓
AI agents call list_all_principals_used_for_syncing_ad_and_aad 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 data about AD/AAD sync principals without modifying or deleting anything. It is a discovery query, placing it in the Read category. Severity is high (not critical) because knowledge of sync principals is operationally sensitive for attackers planning lateral movement, privilege escalation, or domain takeover, but does not directly move money or destroy data.
From the tool's definition Tool name and description indicate it 'List all principal(s) used for syncing AD and AAD' — a query operation that retrieves information about security principals.
Documented attack patterns abuse exactly the kind of access list_all_principals_used_for_syncing_ad_and_aad gives an agent:
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 list_all_principals_used_for_syncing_ad_and_aad:
{
"version": "1",
"default": "deny",
"tools": {
"list_all_principals_used_for_syncing_ad_and_aad": {}
}
}list_all_principals_used_for_syncing_ad_and_aad is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
