Overview

SentinelMCP is a battle-tested MDR framework that brings enterprise-grade alert handling and investigation procedures to Microsoft Sentinel. It eliminates the chaos of manual alert triage through:

• Intelligent Tier Routing - Each alert finds the right handler first time
• Automated FP Detection - Reduce noise by 60-80% in Tier 1
• Smart Escalation - No more "should I escalate this?" decisions
• Forensic-Grade Documentation - Investigation-ready evidence packages
• Skill-Based Assignment - Right person, right skills, right alert

🛠️ Setup & Configuration

Prerequisites

• ✅ Microsoft Sentinel workspace (production or eval)
• ✅ Access to data sources (Defender XDR, Entra ID minimum)
• ✅ Git installed
• ✅ Python 3.8+ OR PowerShell 7+ (for customization)

Installation

# Clone the repository
git clone https://github.com/eshlomo1/SentinelMCP.git
cd SentinelMCP

# Review configuration
cat config.yaml

# Check your workspace ID
grep "workspace_id" config.yaml

Configuration

1. Update workspace details in config.yaml:

   workspace_id: <your-workspace-id>
   tenant_id: <your-tenant-id>
   organization: <your-organization>

2. Review SLAs (config.yaml):

   slas:
     critical: 5 minutes # Tier 1 response time
     high: 15 minutes
     medium: 1 hour
     low: 4 hours

3. Customize agents in agents/:

   • Modify SLAs based on your capacity
   • Add data sources specific to your environment
   • Adjust escalation criteria

🎓 Key Concepts

Tier Architecture at a Glance

Each tier has crystal-clear responsibilities, defined escalation triggers, and measurable outcomes:

Tier	Purpose	SLA	Agents	Key Output
🔴 Tier 1	Rapid Triage	5-15 min	4	Normalized alert + decision
🟠 Tier 2	Deep Analysis	30-60 min	4	Investigation report + escalation decision
🟡 Tier 3	Forensic Excellence	8 hours	4	Root cause + evidence package
🟢 Cloud Hunter	Proactive Hunt	4 hours	4	Threat intel + anomaly data

Smart Escalation Engine

Automatic escalation based on these signals:

• ⚠️ Tier 1→2: Confirmed compromise, lateral movement, data exfiltration attempts
• ⚠️ Tier 2→3: Multi-system compromise, APT indicators, legal hold requirements
• ⚠️ Tier 3→Closure: Investigation complete, remediation plan in place

See DOCS/OPERATIONS/TIER_INTEGRATION.md → Detailed decision criteria + playbooks

🔗 Data Integration

SentinelMCP ingest from 8 major sources with intelligent enrichment at every tier:

• ✅ Microsoft Defender XDR — Endpoint, email, cloud app threats
• ✅ Entra ID — Authentication, identity risk events
• ✅ Azure Security Center — Infrastructure + vulnerability data
• ✅ AWS CloudTrail — Cloud infrastructure activity
• ✅ GCP Audit Logs — Google Cloud operations
• ✅ Third-Party SIEM — Integrate additional tools
• ✅ Threat Intelligence Feeds — External threat context
• ✅ Custom Logs — Application-specific security events

Alert Lifecycle

Every alert follows this intelligent, efficient path:

Raw Alert → Normalize → Enrich → Route → Investigate → Escalate → Close
   (T1)      (T1)       (T1)    (T1)      (T2)        (T3)      (T3)
