Ctxo vs AiDex

Ctxo: Ctxo indexes your codebase into a deterministic graph of symbols, edges, and git history, exposed through 14 semantic MCP tools. It enables AI agents to proactively understand code context, blast radius, and git intent, preventing common mistakes like missing inheritance or reintroducing bugs.; 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.
