The setup involves enabling the MCP server via environment variables, designing two Weaviate collections (code chunks and doc chunks) with appropriate tokenization, ingesting code using AST-aware chunking (Python's ast module or tree-sitter) and docs using heading-based chunking, then connecting Claude Code, Cursor, and VS Code to the same Weaviate endpoint. Hybrid search (BM25 + vector) is highlighted as key for code retrieval since it handles both exact identifier matching and semantic intent queries. The post also covers multi-tenancy for multi-repo organizations, RBAC auth, agent write-back for long-term memory, and embedding model choices. ## Full article daily.dev links to this article rather than hosting it.
