vector_mcp vs mcp-memory-libsql

vector_mcp: VectorMCP is a Ruby framework implementing the MCP server specification. It provides class-based tools, resources, prompts, and supports streamable HTTP transport with authentication, authorization, and middleware.; mcp-memory-libsql: mcp-memory-libsql is a high-performance, persistent memory system for the Model Context Protocol (MCP). It uses libSQL to store entities and relations, providing optimized text search with relevance ranking to enhance LLM context efficiency. It supports both local SQLite and remote libSQL databases with secure authentication.
