Overview

powhttp-mcp is a comprehensive Model Context Protocol server that bridges AI assistants with HTTP traffic analysis. It provides 17 tools for examining HTTP requests/responses, comparing browser vs program traffic, generating TLS/HTTP fingerprints, clustering API endpoints, analyzing GraphQL operations, and even generating Go scrapers from captured traffic. The server integrates specifically with powhttp, a HTTP traffic capture tool, allowing AI assistants to gain deep insights into web communication patterns.
