AI coding tools rely on grep or vector RAG they don't understand your code's call graph or types, so asking about charge() surfaces every unrelated match. Travsr builds a deterministic code graph (tree-sitter + semantic resolution, local SQLite) exposed to AI agents via MCP for precise, ranked answers instead of guesses. 26 first-party tools, 16 languages, VS Code graph view.
