# PCAP Network Analysis

> Use this tool when you need to analyze network packet captures to investigate security threats, troubleshoot connectivity issues, or conduct digital forensics. It takes PCAP files as input from local directories or remote HTTP sources and outputs structured analysis of DNS and DHCP traffic, providing valuable insights for cybersecurity analysts, network engineers, and digital forensics investigators. With support for .pcap and .pcapng formats, it enables AI-assisted interpretation of packet-level data for informed decision-making.

## Description

A modular Python MCP server for analyzing network packet captures (PCAP files) that enables LLMs to perform structured analysis of DNS and DHCP traffic from local directories or remote HTTP sources. Built with scapy for packet parsing and FastMCP for server integration, it features protocol-specific modules with extensible architecture, specialized analysis prompts for security investigation and network troubleshooting, and support for both .pcap and .pcapng formats with configurable packet limits. The implementation includes robust error handling, temporary file management for remote sources, and comprehensive statistics generation, making it valuable for cybersecurity analysts conducting threat detection, network engineers troubleshooting connectivity issues, and digital forensics investigators requiring detailed packet-level analysis with AI-assisted interpretation.
