Charles-mcp

Active·★ 327·MIT·Updated 2026-06-23

Charles MCP Server bridges Charles Proxy with MCP clients, enabling AI agents to read live traffic incrementally, analyze recorded sessions with structured summary-first output, and drill down into details. It supports real-time capture, history analysis, and a reverse engineering toolchain for decoding, replay, and signature discovery, all with token-budget optimized responses.

Charles-mcp sits in the Dev Tooling category, so it is usually better judged by workflow fit, deployment style, and team needs than by isolated features alone. Based on the available metadata, it leans most clearly toward Real-time live capture with incremental reading (cursor-based, no data loss).. A representative use case is Real-time traffic monitoring and debugging for AI agents.. The listed license is MIT. GitHub stars are currently 327. Relevant tags include ai-agent, charles-proxy.

This write-up is based on the project's README and public repository data. We have not hand-tested the tool.
