Ctxo

Overview

Ctxo indexes codebases to create deterministic graphs of symbols, edges, git commits, and anti-patterns, exposing them through 14 semantic MCP tools. It transforms how AI agents interact with code by providing proactive insights instead of reactive file-by-file reading. The solution works across multiple languages with deep analysis for TypeScript, Go, and C#.
