Codanna is a local MCP server and CLI tool designed to enhance AI coding agents by indexing local codebases and exposing code intelligence via the Model Context Protocol. It provides semantic code search, call graph analysis, and symbol-level code navigation, enabling AI assistants to understand and traverse codebases with surgical precision. Built in Rust for speed, it supports rapid R&D workflows and integrates with multiple AI agents including Claude, Gemini, and OpenAI Codex.
