NestJS Protocol Backend FAQs

Question 1

What is the NestJS Protocol Backend?

Accepted Answer

The NestJS Protocol Backend is a NestJS-based server designed to implement the Model Context Protocol (MCP). It provides standardized API endpoints for MCP metadata, JSON-RPC tool invocation, prompts, and resources.

Question 2

How does it simplify API tool development and integration?

Accepted Answer

It simplifies development by automatically registering tools from a designated directory, ensuring type-safe input validation with DTOs, and generating comprehensive Swagger UI documentation for easy testing and API exploration.

Question 3

What kind of tools can I integrate, and how are they called?

Accepted Answer

You can integrate custom tools defined as simple JavaScript/TypeScript objects or classes. These tools are automatically discovered and can be invoked using the standardized JSON-RPC 2.0 `POST /rpc` endpoint.

Question 4

What is the Model Context Protocol (MCP) and how does this backend support it?
