DWD MCP Server

A simple Model Context Protocol (MCP) server that connects Claude Desktop to the Deutsche Wetterdienst (DWD) API for German weather data.

Features

Simple, lightweight Node.js implementation
No dependencies beyond the MCP SDK
Easy to set up and use
Access to DWD weather station data and warnings

Quick Start

Make the setup script executable:
```
chmod +x setup.sh
```
Run the setup script:
```
./setup.sh
```
Restart Claude Desktop
Start using the DWD data in your conversations with Claude!

Available Tools

`get_station_data`

Get current weather data for specific DWD weather stations.

Example usage in Claude:

Can you check the current weather for station 10865 (Berlin-Tegel)?

`get_nowcast_warnings`

Get current nowcast weather warnings in Germany.

Example usage in Claude:

Are there any current weather warnings in Germany? Can you check using the DWD API?

Finding Station IDs

The DWD API requires specific station IDs. You can find these at:

Official DWD station list

Common station IDs:

10381: Berlin-Brandenburg
10865: Berlin-Tegel
10147: Hamburg
10637: Köln-Bonn
10870: Munich

Manual Setup

If the setup script doesn't work for you, you can manually configure Claude Desktop:

Install dependencies:
```
npm install
```

Create or edit ~/.config/claude/claude_desktop_config.json:

{
  "mcpServers": {
    "dwd": {
      "command": "node",
      "args": [
        "/full/path/to/dwd-server.js"
      ]
    }
  }
}

Restart Claude Desktop

Troubleshooting

Make sure Node.js 18+ is installed
Check if the MCP server is running properly: node dwd-server.js
Verify the path in claude_desktop_config.json is correct
Restart Claude Desktop after configuration changes
