✨ MCP Weather Server

A lightweight MCP server built with Python and FastMCP, providing
weather alerts and forecasts via the National Weather Service API.

🛠️ 1. Project Setup

✔️ Step 1 — Install uv

powershell -ExecutionPolicy Bypass -Command "irm https://astral.sh/uv/install.ps1 | iex"

✔️ Step 2 — Create and Set Up the Project

Copy code
uv init weather
cd weather
uv venv
.\.venv\Scripts\Activate.ps1
uv add "mcp[cli]" httpx

✔️ Step 3 — Add the MCP Server Code Create a file named weather.py (or main.py if you prefer) and paste your MCP weather server implementation.

✔️ Step 4 — Run the Server bash Copy code uv run weather.py If the server stays active without errors, it is running correctly ✅.

💬 2. Configure Claude for Desktop Open the Claude config file:

text Copy code %APPDATA%\Claude\claude_desktop_config.json Add (or merge) the following configuration:

json Copy code { "mcpServers": { "weather": { "command": "uv", "args": [ "--directory", "D:/Build-mcp/weather", "run", "weather.py" ] } } } 🔁 After saving, restart Claude Desktop so it picks up the new MCP server.

🔍 3. Testing the Server When everything is wired correctly, Claude should show these tools:

get_alerts

get_forecast

Example Queries You can ask Claude things like:

What are the active weather alerts in Texas?

Give the forecast for 38.5816, -121.4944

If Claude responds using the tools (you’ll see tool calls in the UI), your MCP server is working as expected 🎉.
