Overview

What is Weather MCP Server?

Weather MCP Server is a simple MCP server that provides weather information using the National Weather Service API. It exposes two tools: get_alerts for weather alerts in a US state and get_forecast for weather forecasts at a specific location. It is designed for developers integrating weather data into MCP-compatible clients like Claude for Desktop.

How to use Weather MCP Server?

Clone the repository and set up a Python environment (Python 3.10+). Install dependencies with uv add "mcp[cli]" httpx or pip install "mcp[cli]" httpx. Run the server using mcp dev main.py. Configure Claude for Desktop by adding a JSON entry to its config file with the absolute path to the project and the uv run main.py command. Restart Claude for Desktop, then ask questions like "What's the weather in NY?" to test.

FAQ from Weather MCP Server

What are the prerequisites for using Weather MCP Server?

Python 3.10 or higher is required, along with either the uv package manager (recommended) or pip to install dependencies.

How do I configure Weather MCP Server for Claude for Desktop?

Add a JSON block to the Claude for Desktop config file (claude_desktop_config.json) with the command set to uv and args pointing to your project directory and the main script. Replace the absolute path with your actual project path.

What tools does Weather MCP Server provide?

Two tools are available: get_alerts (requires a US state code) and get_forecast (requires latitude and longitude). Both return weather data from the National Weather Service.

What are common troubleshooting steps?

Verify the configuration file path and absolute path are correct, ensure all dependencies are installed, restart Claude for Desktop, and check your internet connection. The API only works for US locations, so confirm state codes or coordinates are valid.

Does Weather MCP Server require any authentication or API keys?

No; the National Weather Service API is free and does not require an API key. The server connects directly without authentication.
