MCP-Nest vs spring-ai-playground

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.; spring-ai-playground: Spring AI Playground is a cross-platform desktop app for building, testing, validating, and executing MCP tools in a controlled local environment. It enforces a 'No Pass, No Run' workflow where tools must pass local tests before being exposed to agents. It provides a built-in MCP server, secure secret management, and supports multiple platforms.
