## Facts

- Tool: `query_event_log`
- Server: Procmon (`0xhackerfren/procmon-mcp`) — https://policylayer.com/tools/0xhackerfren-procmon-mcp.md
- Homepage: https://github.com/0xhackerfren/ProcMon-MCP
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Allowed

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "query_event_log",
    "arguments": {}
  }
}
```

## Why query_event_log is rated Low

This tool retrieves and queries Windows event log entries using the Get-WinEvent cmdlet. No data is created, modified, deleted, or executed. However, event logs may contain sensitive security information (authentication failures, privilege escalation attempts, etc.), so unauthorized or excessive querying could expose confidential data or support reconnaissance for attacking a system.

From the tool's own definition: "Tool name 'query_event_log' and description 'Query a Windows event log via Get-WinEvent FilterHashtable' indicate a read-only operation that retrieves event log data without modification."

## Use case

AI agents call query_event_log to retrieve information from Procmon without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Procmon:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "query_event_log": {}
  }
}
```
