An MCP server plus a CLI tool that indexes local code into a graph database to provide context to AI assistants.

Unique: Uses Tree-sitter's incremental parsing with language-specific grammars for 14 languages, enabling structural awareness of code relationships rather than text-based pattern matching. Normalizes heterogeneous syntax into a unified graph schema through a language-agnostic entity extraction layer.

vs others: Faster and more accurate than regex-based indexing (Sourcegraph, Ctags) because it understands code structure; broader language support than LSP-only solutions while remaining lightweight and offline-capable.

via “structural codebase indexing with language-aware parsing”

MCP server for Claude Code: 97% token savings on code navigation + persistent memory engine that remembers context across sessions. 106 tools, zero external deps.

Unique: Uses language-specific annotators with AST-based parsing for 5 high-fidelity languages and graceful fallback to generic annotators, creating a unified structural index that persists across sessions. This avoids re-parsing on every query and enables transitive dependency traversal without re-scanning the codebase.

vs others: Outperforms naive full-file-read approaches (like cat or grep) by 97-99% token reduction through surgical symbol-level queries; differs from Copilot/LSP-based tools by maintaining a persistent, queryable index rather than relying on real-time language server state.
