NestJS Protocol Backend

关于

This NestJS-based server provides a robust and standardized implementation of the Model Context Protocol (MCP), acting as a central hub for AI model interactions. It offers well-defined API endpoints for discovering MCP metadata, invoking external tools via JSON-RPC, managing prompts, and serving various resources. Developers can easily extend its capabilities by adding new tools, which are automatically registered, fostering a flexible and scalable environment for integrating diverse functionalities into AI-driven applications.

主要功能

• Flexible tool definition with static `toolName` or filename-based naming conventions.
• Type-safe input validation for tool parameters using DTOs and global `ValidationPipe`.
• Standardized endpoints for MCP metadata, JSON-RPC tool invocation, prompts, and resources.
• Automatic tool registration by scanning `src/tools` directory for object or class-style definitions.
• Auto-generated Swagger UI for comprehensive API documentation and testing.
• 0 GitHub stars

使用案例

• Developing backend services for AI applications that adhere to the Model Context Protocol.
• Creating a centralized gateway for orchestrating and invoking various external tools via JSON-RPC.
