Ctxo vs CodeMCP

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.; CodeMCP: CKB transforms your codebase into a queryable knowledge base, enabling semantic search, impact analysis, dead code detection, ownership lookup, and more through CLI, API, or AI assistants. It reduces AI tool calls by 60-70% with compound operations and integrates seamlessly with MCP-compatible tools.
