AiDex vs agent-shadow-brain

AiDex: AiDex is an MCP server that gives AI coding assistants instant access to your entire codebase through a persistent, pre-built index. It works with any MCP-compatible AI assistant and reduces context consumption for code navigation by 50-80%. Featuring Tree-sitter parsing, incremental updates, and time-based filtering.; agent-shadow-brain: Shadow Brain is the first open-source shared memory and context system for AI coding agents. It allows multiple agents and sub-agents to share a common brain, with features like causal memory chains, dream engine, reputation ledger, and more. It works with 10+ agents and is free and local-first.
