💡 Usage Examples

System Information

# Check system capabilities wireshark_system_info(info_type="all") # → Returns interfaces, capabilities, server status

Live Packet Capture

# Capture HTTP traffic for 30 seconds wireshark_live_capture( interface="eth0", duration=30, filter="tcp port 80", max_packets=1000 ) # → Returns captured packets with analysis

PCAP Analysis

# Comprehensive PCAP analysis wireshark_analyze_pcap( filepath="/path/to/capture.pcap", analysis_type="comprehensive" ) # → File info, protocols, security analysis

Filter Generation

# Generate filter from natural language wireshark_generate_filter( description="Show all HTTP traffic from 192.168.1.0/24", complexity="intermediate" ) # → Returns optimized Wireshark filter

PCAP Operations

# Split large PCAP by time wireshark_pcap_time_slice( input_file="/path/to/large.pcap", start_time="2025-01-01T10:00:00", end_time="2025-01-01T11:00:00" ) # → Creates time-sliced PCAP file # Merge multiple PCAPs wireshark_pcap_merger( input_files=["file1.pcap", "file2.pcap"], output_file="merged.pcap", sort_chronologically=true ) # → Creates chronologically sorted merged file

Security Analysis

# Threat detection wireshark_threat_detector( input_file="/path/to/suspicious.pcap", detection_mode="comprehensive", sensitivity="high" ) # → Threat scores, anomalies, behavioral analysis # DNS tunneling detection wireshark_dns_analyzer( input_file="/path/to/capture.pcap", analysis_type="comprehensive", detect_tunneling=true ) # → DNS patterns, suspicious domains, entropy analysis

🔧 Expected Outputs

Structured JSON Results

All tools return well-structured JSON with:

Status indicators (✅ Success, ❌ Error)
Rich metadata (file sizes, timestamps, statistics)
Analysis results (protocols, conversations, threats)
Recommendations (filter suggestions, security insights)

File Operations

PCAP manipulation tools create properly formatted files:

Time-sliced captures with precise timestamps
Split files with organized naming conventions
Merged files with chronological packet ordering
Converted files maintaining packet integrity

Security Intelligence

Advanced analysis provides:

Threat scores (0-100 risk assessment)
Anomaly detection (statistical analysis)
Pattern recognition (attack signatures)
Behavioral analysis (network health indicators)

🚨 Troubleshooting

Permission Issues (Common)

# Linux: Set capabilities sudo setcap cap_net_raw,cap_net_admin=eip /usr/bin/dumpcap sudo usermod -a -G wireshark $USER # macOS: Run Wireshark as admin once sudo /Applications/Wireshark.app/Contents/MacOS/Wireshark # Windows: Run as Administrator

Tool Not Found

Ensure Wireshark is installed and in PATH
Check wireshark_validate_setup tool for missing dependencies
Verify configuration paths in Claude Desktop config

No Packets Captured

Check interface permissions with wireshark_system_info
Verify network traffic exists on selected interface
Try different interface (eth0, wlan0, any)
