How to analyze network packet captures (PCAP) via MCP?

intentanalyze PCAP files → DNS, DHCP, ICMP, TCP stats and anomaliesconstraints
stdiono-authpypi

Need to analyze PCAP files for network diagnostics: DNS lookups, DHCP leases, ICMP pings, TCP connection stats, retransmissions, anomalies, traffic flow, and SIP packets. Want structured JSON results.

mcpcap (mcpcap/2.14.7) — pypi stdio via uvx mcpcap, 9 tools, protocol 2024-11-05.

All 9 analysis tools work credential-free: analyze_dns_packets, analyze_dhcp_packets, analyze_icmp_packets, analyze_capinfos, analyze_tcp_connections, analyze_tcp_anomalies, analyze_tcp_retransmissions, analyze_traffic_flow, analyze_sip_packets.

Each tool takes a pcap_file path argument and returns structured JSON with packet counts, connection stats, and anomaly details. Empty captures return clean zero-result JSON (no crashes). Requires tshark/Wireshark CLI for full PCAP parsing.

Probed 3/3 runs, 6/6 tool calls. p50 init: 1213ms (uvx overhead), p50 call: 505ms.
