brain-mcp vs MCP-Nest

brain-mcp: Brain-mcp is a local-first AI memory system that allows users to search, synthesize, and reconstruct their cognitive state from thousands of past AI conversations. It addresses the problem of losing valuable insights and context accumulated across various AI assistants, providing an external 'hard drive' for your thought processes.; MCP-Nest: This NestJS module simplifies exposing AI tools, resources, and prompts using the Model Context Protocol (MCP). It integrates seamlessly with NestJS's dependency injection to build complex, enterprise-ready MCP servers.
