Exemplo de Servidor MCP

What is Exemplo de Servidor MCP?

Exemplo de Servidor MCP is a sample implementation of a Model Context Protocol (MCP) server built with Node.js/TypeScript. It provides two tools for retrieving weather information from the US National Weather Service (NWS) API: get-alerts for active weather alerts by state code, and get-forecast for weather forecasts by geographic coordinates. This project is intended for educational purposes and demonstrates how to build an MCP server with external API integration and data validation.

How to use Exemplo de Servidor MCP?

Install by cloning the repository, running npm install and npm run build. After building, start the server with node build/main.js or, if linked as a binary, with weather. The server listens on stdio and accepts MCP requests.

What are the dependencies and runtime requirements?

Node.js and npm are required. After installing dependencies with npm install, the server is built with npm run build and runs on Node.js.

How does the server communicate?

It uses stdio transport as defined by the MCP SDK (@modelcontextprotocol/sdk). The server reads requests from standard input and writes responses to standard output.

Does it require authentication?

No authentication is mentioned. The NWS API used does not require an API key for these endpoints.

Where does the weather data come from?

All weather data is fetched live from the public National Weather Service (NWS) API. No local data is stored or cached by the server.
