1. What CodeGraph Is CodeGraph is a local-first code intelligence tool. It parses a codebase with tree-sitter, stores symbols, relationships, and files in a local SQLite database, and exposes them as a queryable knowledge graph through MCP, a CLI, and a TypeScript API. Put simply, it turns “grep, glob, and Read all over the code” into an index built ahead of time, so an AI assistant can answer structural questions with just a few queries.
