MCP Weather Server Setup Guide
This guide walks you through setting up and running a weather server using the MCP SDK and uv, a Rust-based Python package manager.
✅ Prerequisites
Make sure you have the following installed before proceeding:
- Claude.ai account (any account type works — MCP is supported)
- Claude Desktop App (available for macOS and Windows)
- Code Editor (e.g., Visual Studio Code)
uv— A fast Python package manager written in Rust
Install uv:
macOS (via Homebrew):
brew install uv
Windows (via WinGet):
winget install --id=astral-sh.uv -e
⚙️ Project Setup
Follow these steps to create and configure the project environment:
-
Create the project folder: mkdir mcp-server-weather cd mcp-server-weather
-
Initialize a new
uvproject: uv init -
Create a virtual environment: uv venv
-
Activate the virtual environment:
macOS / Linux: source .venv/bin/activate
Windows (PowerShell): .venv\Scripts\Activate.ps1
To deactivate the virtual environment: deactivate
- Install required packages: uv add "mcp[cli]" httpx
🚀 Running and Testing the MCP Server
-
Start the MCP server in development mode: mcp dev server.py
-
Open http://localhost:5173 in your browser
-
In the MCP Inspector:
- Click Connect
- Go to the Tools tab
- Click List Tools
- Select get_current_weather
- Enter latitude and longitude (e.g.,
63.4463991, 10.8127596) - The Tool Result section will display the JSON weather data
-
To stop the server: Ctrl+C
📝 Notes
- Ensure your server script is named
server.pyand located in the root of your project. - The MCP Inspector is a helpful tool for interacting with and debugging tools during development.
