AI-Based Windows Event Log Analysis

Question

Hi everyone,

I am exploring a solution for Windows Event Log analysis in an enterprise environment and looking for recommendations.

Requirement: I want to analyze Windows Event Logs using plain English queries. The idea is that an admin can ask questions like:

• “Is device XYZ successfully Entra ID joined?”

“Did user ABC complete Intune enrollment?”

“What issue caused the enrollment failure?”

“Which event log path contains the related logs?”

“Show the exact error event and explain it in simple English.”

Example: For Entra ID Join / Device Registration, logs are available under:

Applications and Services Logs → Microsoft → Windows → User Device Registration → Admin

I am looking for a system/tool that can:

Read and correlate Windows Event Logs automatically

Convert technical events/errors into plain English explanations

Identify relevant log sources and event IDs

Support troubleshooting scenarios across Entra ID, Intune, Windows enrollment, authentication, compliance, etc.

Possibly support natural language querying (AI-assisted)

Questions:

Are there any existing inbuilt Microsoft tools that already provide this capability?

Has anyone built a custom MCP server or AI-based solution for this kind of log analysis?

Would using an MCP server with LLM + Event Log ingestion be a good approach?

I am considering building a custom MCP server that can:

Read Windows Event Logs

Map known Event IDs to troubleshooting scenarios

Use AI/LLM to summarize findings

Return plain English explanations with exact log paths

Would love to hear suggestions, architectures, best practices, or existing tools that already solve this problem.

Microsoft provides several building blocks for log collection, correlation, and natural-language analysis, but not a single out-of-the-box tool that does everything described directly on raw Windows Event Logs. The closest native capabilities today are:

1. Microsoft Entra logs + Security Copilot for natural language For Entra ID, Intune-related identity events, and sign-ins, the recommended approach is to use Microsoft Entra logs rather than raw Windows Event Logs:
   • Microsoft Entra audit logs and sign-in logs capture device registration, authentication, and directory changes.
   • These logs can be queried and analyzed using Microsoft Security Copilot with natural language prompts.
   • Security Copilot supports scenarios such as:
     • Reviewing and troubleshooting sign-in activities.
     • Investigating audit activities (group, security, authentication changes).
     • Monitoring user activity and security posture.
   Security Copilot lets admins ask questions in plain English against Entra sign-in and audit logs, for example:
   • “Show failed sign-ins for user ABC and summarize the cause.”
   • “List risky sign-ins for the last 24 hours and explain the risk reasons.”
   For Entra ID monitoring and health, Security Copilot can quickly access and analyze:
   • Sign-in logs
   • Audit logs
   • Recommendations and health alerts
   • SLA performance data
   This aligns with the requirement for AI-assisted, natural-language troubleshooting across Entra ID and authentication scenarios.
2. Centralizing logs for correlation and automation For broader infrastructure and privileged account monitoring (including Windows devices), Microsoft recommends centralizing logs and then using SIEM/analytics tools:
   • Microsoft Entra audit logs and sign-in logs
   • Microsoft 365 audit logs
   • Azure Key Vault logs/insights
   These can be integrated with:
   • Microsoft Sentinel – SIEM with analytics and automation.
   • Azure Monitor – for automated monitoring, alerting, and workbooks.
   • Azure Event Hubs – to stream logs into other SIEMs (Splunk, QRadar, etc.).
   Once logs are in Sentinel or Azure Monitor (Log Analytics), Kusto queries can be used, and Security Copilot can be layered on top for natural-language analysis of those datasets.
3. Windows Event Forwarding (WEF) for device logs For raw Windows Event Logs (including device join, enrollment, and OS events), the recommended pattern is:
   • Use Windows Event Forwarding (WEF) to collect events from endpoints into a central Windows Event Collector (WEC) server.
   • Use two subscription types:
     • Baseline subscription – for all devices, lower-volume operational events.
     • Suspect subscription – for selected devices, higher-volume forensic events.
   • Forwarded events can then be sent to:
     • A Security Event Manager (SEM/SIEM) such as Microsoft Sentinel for real-time correlation and alerting.
     • A MapReduce system (HDInsight/Hadoop/Data Lake) for long-term storage and advanced analytics, including ML.
   This architecture is the standard way to:
   • Read and correlate Windows Event Logs at scale.
   • Feed them into analytics/AI layers.
4. MCP Server + Microsoft Graph activity logs For an MCP-based solution, Microsoft provides Microsoft MCP Server for Enterprise (preview) with logging via Microsoft Graph activity logs:
   • MCP Server uses Microsoft Graph APIs; every request is captured in Microsoft Graph activity logs.
   • Logs can be filtered by the MCP server appId in Log Analytics using Kusto queries.
   This pattern shows how to:
   • Instrument an MCP server.
   • Use Log Analytics for monitoring and querying MCP activity.
   Extending this pattern, an MCP server that:
   • Reads Windows Event Logs (or better, queries centralized logs in Log Analytics/Sentinel).
   • Maps known Event IDs to troubleshooting scenarios.
   • Uses an LLM to summarize and explain findings.
   would be a sound architecture. The MCP server would act as the broker between:
   • Natural-language queries from admins.
   • Kusto queries over centralized logs (Entra, Intune, Windows, etc.).
   • LLM-based summarization and explanation.
5. Existing Microsoft capabilities vs. custom solution Based on the provided information:
   • Inbuilt tools that partially meet requirements:
     • Microsoft Entra + Security Copilot for natural-language analysis of Entra sign-in and audit logs.
     • Microsoft Sentinel + Azure Monitor + Event Hubs + WEF for centralized log collection, correlation, and analytics.
   • These tools do not natively expose a single “ask anything about any Windows Event Log in plain English” interface, but they provide:
     • Centralized, queryable logs (Kusto/Log Analytics).
     • AI-assisted analysis for Entra scenarios via Security Copilot.
   • A custom MCP server that:
     • Uses Log Analytics/Sentinel as the data source (rather than reading local .evtx files directly).
     • Leverages Microsoft Graph activity logs for its own telemetry.
     • Integrates with an LLM for natural-language Q&A and summarization.
     is a recommended approach to meet the full set of requirements.

Summary of recommended architecture

• Collection:
  • Use Windows Event Forwarding to centralize Windows Event Logs.
  • Stream Entra audit logs, sign-in logs, Microsoft 365 audit logs, and Key Vault logs into Log Analytics/Sentinel via Azure Monitor/Event Hubs.
• Analytics and AI:
  • Use Microsoft Sentinel/Azure Monitor for correlation, alerting, and Kusto-based queries.
  • Use Microsoft Security Copilot for natural-language analysis of Entra sign-in and audit logs.
  • Optionally, build a custom MCP server that:
    • Executes Kusto queries over Log Analytics/Sentinel.
    • Maps Event IDs and patterns to troubleshooting playbooks.
    • Uses an LLM to produce plain-English explanations and surface exact log paths and events.

This combination provides the Microsoft-native foundation for the AI-based Windows Event Log analysis scenario described.
