AI agents call ad_smb_enum to retrieve information from Zebbern Kali MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs enumeration (read/discovery) of SMB shares and related information on a target system — a passive reconnaissance action with no direct data modification. However, the severity is high because SMB enumeration against systems without authorization is an offensive security action that reveals sensitive network topology, share names, and potentially accessible resources.

Documented attack patterns abuse exactly the kind of access ad_smb_enum gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Zebbern Kali MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for ad_smb_enum:
{
"version": "1",
"default": "deny",
"tools": {
"ad_smb_enum": {}
}
}ad_smb_enum is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Enumerate SMB shares and information on a target. It is categorised as a Read tool in the Zebbern Kali MCP MCP Server, which means it retrieves data without modifying state.
Register the Zebbern Kali MCP server in PolicyLayer and add a rule for ad_smb_enum: 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 Zebbern Kali MCP. Nothing to install.
ad_smb_enum 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 ad_smb_enum 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 ad_smb_enum. 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.
ad_smb_enum is provided by the Zebbern Kali MCP server (zebbern/zebbern-kali-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
