codebase-memory-mcp vs Charles-mcp
codebase-memory-mcp: codebase-memory-mcp is a structural analysis backend that indexes codebases into a persistent knowledge graph, drastically reducing token usage for code exploration by providing precise structural results. It integrates with AI assistants like Claude Code, offering advanced capabilities such as call graph tracing, architecture overviews, and dead code detection.; Charles-mcp: 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.
01
TL;DR
Choose codebase-memory-mcp if…Code exploration and understanding: Quickly understand codebase architecture, find functions, and trace call paths without high token costs.
Choose Charles-mcp if…Real-time traffic monitoring and debugging for AI agents.
