semble vs mcp-windbg
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.; mcp-windbg: This MCP server integrates with CDB to enable AI models to analyze Windows crash dumps and connect to remote debugging sessions using WinDbg/CDB. It allows users to execute debugger commands through natural language queries. The server supports crash dump analysis, live debugging, and directory analysis.
