CogniLayer vs MCP-Nest

CogniLayer: CogniLayer is an advanced tool that equips AI agents with persistent knowledge and deep code intelligence, preventing them from repeatedly learning your codebase. It significantly saves tokens by compressing context and providing immediate access to architectural understanding, past decisions, and bug fixes.; 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.
