semble vs IDAssistMCP
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.; IDAssistMCP: IDAssistMCP is a standalone MCP server plugin for IDA Pro 9.x that exposes IDA's analysis capabilities to LLM clients. It provides 38 MCP tools, 8 resources, and 7 guided prompts for reverse engineering tasks. The server supports SSE and Streamable HTTP transports and includes features like thread-safe IDB modifications, LRU cache, and async task management.
