NetForensicMCP v2.1

（Formerly WireMCP, Now Focused on Offline Forensic Analysis）

English | 中文

NetForensicMCP (formerly WireMCP) is a Model Context Protocol (MCP) server designed to empower Large Language Models (LLMs) with advanced offline network traffic analysis and threat intelligence capabilities. Built on top of Wireshark's tshark, NetForensicMCP provides comprehensive PCAP analysis tools for cybersecurity professionals, threat hunters, and network forensics investigators.

🚀 Key Features

Core Analysis Engine

• Smart Stream Analysis: Intelligent content chunking to handle large PCAP files without token overflow
• Threat Intelligence Integration: Built-in URLhaus blacklist checking with stream correlation
• Credential Extraction: Automated detection of plaintext credentials across multiple protocols
• High-Frequency IP Analysis: Proactive threat hunting through top communicator identification

Advanced Tools

• get_summary_stats: Protocol hierarchy statistics for traffic composition overview
• get_conversations: TCP/UDP conversation analysis with stream indexing
• extract_stream_content: Precise payload extraction with pagination support
• get_stream_info: Content size estimation to prevent token overflow
• extract_stream_chunks: Automated large stream segmentation
• get_top_ips: High-frequency communicator identification for proactive analysis
• check_threats: Batch IP threat scanning with stream correlation
• extract_credentials: Multi-protocol credential detection with context
• capture_packets: Legacy live traffic capture (preserved for compatibility)

🔍 How It Empowers LLMs

NetForensicMCP transforms complex network forensics into LLM-accessible intelligence by:

• 🎯 Threat-Driven Analysis: Prioritizes high-risk indicators over raw data processing
• 📊 Structured Intelligence: Converts PCAP data into actionable threat intelligence
• ⚡ Efficient Investigation: Optimized workflow prevents token exhaustion
• 🔗 Correlation Engine: Links disparate network events into coherent attack narratives
• 📝 Automated Reporting: Generates comprehensive security reports with IOCs and recommendations

🛡️ Cybersecurity Use Cases

• 🕵️ Threat Hunting: Proactive identification of APT activities and C2 communications
• 🔍 Incident Response: Rapid forensic analysis of network evidence
• 📋 Compliance Auditing: Credential leak detection and security gap identification
• 🚨 IOC Extraction: Automated indicator of compromise discovery
• 📖 Attack Reconstruction: Timeline analysis and attack path visualization

📋 Installation

Prerequisites

• Operating System: Windows, macOS, or Linux
• Wireshark: Download here (tshark must be in PATH)
• Node.js: v16+ recommended
• npm: For dependency management

Setup

1. Clone the repository:

   git clone https://github.com/kylecui/NetForensicMCP.git
   cd NetForensicMCP
   

2. Install dependencies:

   npm install
   

3. Launch the MCP server:

   node index.js
   

Note: NetForensicMCP auto-detects tshark or falls back to common installation paths on all platforms.

⚙️ MCP Client Configuration

Cursor IDE

Edit mcp.json in Cursor → Settings → MCP:

{
  "mcpServers": {
    "netforensicmcp": {
      "command": "node",
      "args": [
        "/ABSOLUTE_PATH_TO/NetForensicMCP/index.js"
      ]
    }
  }
}

Claude Desktop

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "wiremcp": {
      "command": "node",
      "args": ["C:\\path\\to\\NetForensicMCP\\index.js"]
    }
  }
}

🔬 Example Analysis Workflows

Threat Intelligence Analysis

# Batch threat scanning with stream correlation
check_threats → extract_credentials → get_top_ips
↓
ip_reputation (parallel) → ioc_detection → domain_analysis
↓
extract_stream_content (targeted) → comprehensive_report

Advanced Forensics

# Large PCAP investigation
get_summary_stats → get_conversations → get_stream_info
↓
extract_stream_chunks → extract_stream_content (paginated)
↓
correlation_analysis → timeline_reconstruction

📊 Sample Output

Threat Analysis Report

⚠️  THREATS DETECTED (2):
🚨 192.168.1.100 - Streams: [tcp:0, tcp:2, udp:1]
🚨 10.0.0.50 - Streams: [tcp:5]

📋 RECOMMENDED NEXT STEPS:
1. Use threat intelligence tools to analyze these IPs
2. Extract stream content for streams containing these IPs  
3. Focus investigation on: 192.168.1.100, 10.0.0.50

Stream Content Analysis

Content of tcp stream 0 (chars 0-15000 of 45230):
POST /api/upload HTTP/1.1
Host: suspicious-domain.com
Authorization: Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9...

[TRUNCATED - More content available. Use offset=15000 to get the next chunk.]

🎯 Advanced Features

Smart Token Management

• Intelligent Chunking: Automatic content segmentation prevents API limits
• Pagination Support: Seamless navigation through large datasets
• Size Estimation: Proactive content size assessment
• Parallel Processing: Efficient batch operations

Threat Intelligence Integration

• URLhaus Integration: Comprehensive malware URL database checking
• Stream Correlation: Links threats to specific communication flows
• IOC Extraction: Automated indicator discovery and validation
• Proactive Scanning: Top communicator threat assessment
