mcp-duckdb-memory-server vs crg

Q: Which is better, mcp-duckdb-memory-server or crg?

By GitHub stars, crg has more community adoption, but the best choice depends on your specific use case.

mcp-duckdb-memory-server: This project is an enhanced version of the MCP Knowledge Graph Memory Server, replacing its original JSON file backend with DuckDB. This upgrade significantly improves performance, scalability, and query flexibility by leveraging DuckDB's fast query processing and SQL interface.; crg: `crg` (formerly `better-code-review-graph`) is a local-first knowledge graph tool for codebases, enabling token-efficient code reviews through semantic search, call-graph resolution, and structural analysis. It integrates with AI agents via MCP for precise context provision, leveraging local ONNX embeddings or cloud models for enhanced code understanding and security scanning.
