Gearlynx vs Charles-mcp

Gearlynx: Gearlynx is a highly accurate cross-platform Atari Lynx emulator written in C++. It supports Windows, macOS, Linux, BSD, and RetroArch, and features an embedded MCP server for AI-assisted debugging and tooling.; 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.
