dat vs MCP-Nest

dat: DAT (Data Ask Tool) is an enterprise-grade AI framework that enables business users to interact with databases using natural language, eliminating the need for complex SQL queries. It ensures high-quality and deterministic results through a pre-modeled semantic layer and an Askdata Agent workflow.; 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.
