NestJS

About

This NestJS module introduces the Model Context Protocol (MCP), enabling developers to seamlessly integrate custom 'tools' and prompts into their applications for use with Large Language Models (LLMs) or via HTTP endpoints. It simplifies the process of creating callable functions and context-aware prompts through decorators, offering automatic detection, robust input validation, and native support for OpenAI Function Calls, streamlining the development of intelligent, interactive services.

Key Features

• Automatic detection and exposure of all registered tools and prompts.
• Seamless integration with OpenAI Function Calls and dedicated HTTP endpoints.
• Built-in input data validation for tools.
• Declarative prompt registration using `@McpPrompt()` decorators.
• 1 GitHub stars
• Declarative tool registration using `@McpTool()` decorators.

Use Cases

• Building AI agents that interact with specific application logic via predefined tools.
• Exposing internal NestJS services as callable functions for Large Language Models.
• Creating dynamic and context-aware prompts for LLM applications.
