[WIP] List all principal(s) with privileged access to Azure Tenancy (Required: azurehound)
AI agents call list_principals_with_azure_tenancy_access 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 performs a read-only query against Active Directory/Azure environments to enumerate principals with Azure tenancy access. While the information retrieved is highly sensitive (privileged access paths that could be exploited for lateral movement or privilege escalation), the tool itself performs no side effects, modifications, or code execution.
From the tool's definition Tool name contains 'list' and description states 'List all principal(s)' — a retrieval operation with no modification, deletion, or execution semantics. The tool queries and enumerates principals with specific permission characteristics in Azure.

Documented attack patterns abuse exactly the kind of access list_principals_with_azure_tenancy_access 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_principals_with_azure_tenancy_access:
{
"version": "1",
"default": "deny",
"tools": {
"list_principals_with_azure_tenancy_access": {}
}
}list_principals_with_azure_tenancy_access is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

[WIP] List all principal(s) with privileged access to Azure Tenancy (Required: azurehound). It is categorised as a Read tool in the BloodHound MCP MCP Server, which means it retrieves data without modifying state.
Register the BloodHound MCP server in PolicyLayer and add a rule for list_principals_with_azure_tenancy_access: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches BloodHound MCP. Nothing to install.
list_principals_with_azure_tenancy_access is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_principals_with_azure_tenancy_access rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for list_principals_with_azure_tenancy_access. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
list_principals_with_azure_tenancy_access is provided by the BloodHound MCP server (stevenyu113228/bloodhound-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
