Turns your codebase into a queryable semantic graph across 38 languages and exposes it through 42 MCP tools. Ask for callers, callees, impact analysis, circular dependencies, or AI-curated context for a specific task (explain, modify, debug, test). It runs locally via tree-sitter, includes a persistent memory layer for cross-session notes, and ships with a VS Code extension plus GitHub Action for PR reviews. The `--graph-only` flag skips embeddings for fast CI runs. Includes agent rule files that teach Claude, Cursor, and Windsurf to query the graph before falling back to grep. Useful when you need structured code intelligence instead of full-text search, especially for refactoring, onboarding, or understanding call chains in large polyglot repos.
