Comprehensive user activity investigation. Correlates Browser History, ShellBags, LNK files, and RecentDocs to build a complete picture of user activity. Answers: What did the user browse? What files did they access? What folders did they navigate?
AI agents call investigate_user_activity 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 reads and correlates forensic artifacts (browser history, shell bags, LNK files, recent documents) to reconstruct user activity. It is purely investigative/read-only with no write or destructive side effects. Severity is medium because it accesses potentially sensitive personal data including browsing history and file access patterns, which could expose private user information if misused.
From the tool's definition Correlates Browser History, ShellBags, LNK files, and RecentDocs to build a complete picture of user activity
Documented attack patterns abuse exactly the kind of access investigate_user_activity 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 investigate_user_activity:
{
"version": "1",
"default": "deny",
"tools": {
"investigate_user_activity": {}
}
} investigate_user_activity is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Comprehensive user activity investigation. Correlates Browser History, ShellBags, LNK files, and RecentDocs to build a complete picture of user activity. Answers: What did the user browse? What files did they access? What folders did they navigate?. 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 investigate_user_activity: 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.
investigate_user_activity 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 investigate_user_activity 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 investigate_user_activity. 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.
investigate_user_activity 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.
