The Weather MCP Server retrieves real-time weather information for specified cities using the OpenWeatherMap API.
Fetch Weather Data: Get detailed weather reports including temperature, humidity, wind speed, sunrise/sunset times, and weather descriptions
Metric Units: Weather data is provided in metric units (e.g., Celsius for temperature)
Integration: Can be configured to work with Claude Desktop for weather data retrieval
Developer-Friendly: Supports manual installation and configuration for development environments
Uses .env files for configuration management, particularly for storing the OpenWeatherMap API key
Includes instructions for cloning the repository as part of the setup process
Offers specific setup instructions for Linux environments
Includes macOS-specific setup instructions for the virtual environment
Requires Python 3.12 or higher for running the server
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Weather MCP Server what's the weather like in London today?"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.

Scored across 1 tool
With only one tool, there is no possibility of ambiguity or overlap between tools. The single tool has a clear, distinct purpose of fetching weather reports for a city.
The single tool name 'weather' is straightforward and descriptive. Since there is only one tool, naming consistency is inherently perfect with no deviations or mixed conventions to evaluate.
A single tool for a weather server is too few for the apparent scope, as it lacks essential operations like forecasts, historical data, or multi-location queries. This minimal set limits functionality and may cause agent failures in broader weather-related tasks.
The tool surface is severely incomplete for a weather domain, missing obvious gaps such as forecasts, alerts, or location-based searches. While it covers basic current weather, agents will struggle with common weather-related workflows due to these significant omissions.
