Local RAG + MCP for Claude with zero external dependencies—elegant constraint execution.
Pure Rust CPU-only code search with persistent index beats transformer-heavy alternatives.
MCP integration with Cursor and Claude Code sets this apart from generic RAG tools.
AST-backed deterministic edits: AI never hallucinates syntax or misses call sites again.
Tree-sitter + FTS5 + MCP = tokens saved for AI agents to actually code, not search.
Hybrid BM25 + vector search via MCP beats pure keyword or pure semantic for API docs.
