AI agents call list_high_value_targets 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 queries and retrieves information about high-value targets in an Active Directory environment. While it performs no write, destructive, execute, or financial operations, the severity is elevated to 'high' because misuse could expose critical security intelligence about valuable attack targets (domain controllers, administrative accounts, sensitive resources) that an adversarial AI agent could exploit for…
From the tool's definition Tool name 'list_high_value_targets' and description 'List high value target(s)' indicate data retrieval without modification.
Documented attack patterns abuse exactly the kind of access list_high_value_targets 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_high_value_targets:
{
"version": "1",
"default": "deny",
"tools": {
"list_high_value_targets": {}
}
}list_high_value_targets is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the BloodHound MCP server in PolicyLayer and add a rule for list_high_value_targets: 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_high_value_targets 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_high_value_targets 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_high_value_targets. 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_high_value_targets 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.
