Search for security events by type: logon, failed_logon, process_creation, etc. Supports pagination with offset.
AI agents call evtx_security_search 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 queries and retrieves security event log data from EVTX files. The description explicitly uses 'Search' and lists read-only operations (logon event analysis, process creation review). No modification, deletion, code execution, or financial impact is possible. Pagination support confirms it is a retrieval mechanism.
From the tool's definition Tool name 'evtx_security_search' and description 'Search for security events by type: logon, failed_logon, process_creation, etc. Supports pagination with offset.' indicate query/search operation on Windows Event Logs without modification or execution.
Documented attack patterns abuse exactly the kind of access evtx_security_search 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 evtx_security_search:
{
"version": "1",
"default": "deny",
"tools": {
"evtx_security_search": {}
}
}evtx_security_search 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.
Search for security events by type: logon, failed_logon, process_creation, etc. Supports pagination with offset. 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 evtx_security_search: 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.
evtx_security_search 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 evtx_security_search 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 evtx_security_search. 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.
evtx_security_search 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.
Free to start. No card required.
