# Mcpcap (MCP server)

> Mcpcap is an MCP server that adds tools to AI assistants such as Claude Desktop, Claude Code and Cursor. An MCP server for analyzing PCAP files. It has 51 GitHub stars, is released under the MIT license and runs locally with uvx mcpcap.

A modular Python MCP (Model Context Protocol) server for analyzing PCAP files. mcpcap exposes protocol-specific analysis tools that accept a local file path or remote HTTP URL at call time, so the server stays stateless and works cleanly with MCP clients.
