Look up IP address reputation on VirusTotal.
AI agents call vt_lookup_ip to retrieve information from Windows Forensics MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries data (IP reputation information) from VirusTotal without any side effects, code execution, data modification, or destructive operations. It is purely informational and read-only. The blast radius is minimal—incorrect use might retrieve misleading threat intelligence but cannot modify systems, execute code, or cause data loss.
From the tool's definition Tool name 'vt_lookup_ip' and description 'Look up IP address reputation on VirusTotal' indicate a query/lookup operation against an external threat intelligence service with no modification or execution of code.
Documented attack patterns abuse exactly the kind of access vt_lookup_ip gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Windows Forensics MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for vt_lookup_ip:
{
"version": "1",
"default": "deny",
"tools": {
"vt_lookup_ip": {}
}
}vt_lookup_ip is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Look up IP address reputation on VirusTotal. It is categorised as a Read tool in the Windows Forensics MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Windows Forensics MCP Server MCP server in PolicyLayer and add a rule for vt_lookup_ip: 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 Windows Forensics MCP Server. Nothing to install.
vt_lookup_ip 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 vt_lookup_ip 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 vt_lookup_ip. 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.
vt_lookup_ip is provided by the Windows Forensics MCP Server MCP server (x746b/winforensics-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Windows Forensics MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
