"A Java-based MCP server" matching MCP servers:

Official aviation data MCP by Flight Master DAST (航班管家 DAST), providing flight status, route search, onboard comfort, delay and cancellation risk, airport weather forecasts, and real-time or historical flight trajectories.

A Model Context Protocol server that provides tools to fetch weather alerts for US states and forecasts based on latitude/longitude coordinates using the US National Weather Service API.

Provides real-time weather data and current conditions for major Chinese cities and global locations using the wttr.in API. This HelloAgents-based server enables querying of temperature, humidity, and weather status without requiring an external API key.

A minimal Python-based server that provides real-time weather data and a safe mathematical expression evaluator. It enables users to fetch current weather conditions and perform complex calculations using the Model Context Protocol.

Enables real-time weather queries for 400+ cities in China through the Seniverse Weather API. Provides secure weather data access with HMAC-SHA1 authentication and full MCP protocol compatibility.

A Python-based MCP server that provides real-time weather information using the National Weather Service API, supporting both synchronous and asynchronous HTTP requests.

A weather query MCP server based on FastMCP, supporting Chinese city names and fetching real-time weather data from wttr.in.

A Python MCP server with JWT authentication and sample tools (weather + Bitcoin price), plus an AI agent that uses OpenAI to reason about and call those tools.

MCP server that provides current weather and forecasts via Open-Meteo API, with an optional ML-based next-day max temperature prediction.

Fetches precipitation forecasts for any location using Buienradar, providing real-time rain predictions for the next two hours based on latitude and longitude coordinates.

MCP server for SMHI weather data, providing current conditions, hourly and daily forecasts, and daily summaries for northern Europe.

MCP server for worldwide weather data, using high-resolution GeoSphere Austria data for the Alpine region and Open-Meteo elsewhere. Provides current conditions, hourly forecasts, and daily outlooks with compact emoji-markdown output.

One-call Australian weather plumbing for current and historical data — cited responses for practical analysis, not a data broker.

MCP server providing weather forecast and geocoding tools using Open-Meteo API, with examples of basic and agent-based clients.

Provides climate data for 3,833 destinations including sunshine scores, temperatures, rainfall, and sea temperature, enabling users to find sunny destinations and compare climates via three tools.

Enables AI assistants to retrieve current weather conditions and forecasts for specified locations by geocoding places and pulling data from Open-Meteo, with optional natural-language summaries via Groq.

An unofficial MCP server that provides access to Indonesia's BMKG data, including real-time earthquake reports, village-level weather forecasts, and extreme weather alerts. It enables users to search for location codes and retrieve detailed meteorological and geophysical information through natural language.

AI assistants can size heat pumps, estimate energy costs, and verify cold-climate performance using bundled data and no API keys.

Enables AI assistants to retrieve current weather conditions and forecasts for any location via natural language, with optional AI-generated summaries.

Enables LLMs to retrieve weather forecasts for Israeli cities via browser automation and USA weather via API, maintaining state across tool calls for sequential operations.
