Charles-mcp vs semble
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.; semble: Semble is a high-performance code search library designed for AI agents, providing instant access to precise code snippets. It offers significantly faster indexing and querying compared to transformer models, achieving 99% of their retrieval quality while running entirely on CPU without external dependencies.
