engram-rs vs MCP-Nest

engram-rs: engram-rs is a memory engine for AI agents that organizes knowledge along two axes: time (three-layer decay & promotion) and space (self-organizing topic tree). It intelligently promotes important memories, fades noise, and automatically clusters related knowledge, providing a more effective alternative to flat memory stores.; 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.
