[WIP] Route from principal(s) to Azure VM (Required: azurehound)
AI agents call route_principals_to_azure_vm 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.
Although this tool queries sensitive security data (privilege escalation paths in Azure environments), it performs reconnaissance and analysis only—no modifications, executions, or destructive actions. The 'route' terminology means pathfinding/querying, not network routing or command execution.
From the tool's definition Tool name 'route_principals_to_azure_vm' and description state it routes/queries paths from principals to Azure VMs.
Documented attack patterns abuse exactly the kind of access route_principals_to_azure_vm 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 route_principals_to_azure_vm:
{
"version": "1",
"default": "deny",
"tools": {
"route_principals_to_azure_vm": {}
}
}route_principals_to_azure_vm is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

[WIP] Route from principal(s) to Azure VM (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 route_principals_to_azure_vm: 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.
route_principals_to_azure_vm 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 route_principals_to_azure_vm 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 route_principals_to_azure_vm. 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.
route_principals_to_azure_vm 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.
