mcp-duckdb-memory-server and mcp-database-server
The two tools are competitors within the "sql-database-mcp" category, as both provide a Model Context Protocol (MCP) server for querying SQL databases, with tool A specifically utilizing DuckDB for in-memory operations, and tool B offering broader support for SQLite, PostgreSQL, and MySQL.

MCP Memory Server with DuckDB backend
This tool helps large language models (LLMs) remember past conversations and learned facts more effectively. It takes in user interactions, facts, and relationships, and stores them in a structured way that the LLM can easily query. This is for developers building AI agents or applications that need an LLM to maintain a persistent, searchable memory of its interactions.
