🚨 Quick Note: If the install buttons below open in your browser instead of VS Code, use Method 1 below for manual configuration - it's more reliable!

🚀 Easy Installation Methods

🎯 Method 1: NPM Package (Recommended)

Install directly from npm with automated setup:

npm install -g mohaimen-weather-mcp

Then in your settings just add

"<name of your server>": 
{
   "command": "npx",
   "args": [
      "mohaimen-weather-mcp"
   ],
   "env": {
      "OPENWEATHER_API_KEY": "<YOUR_KEY>"
   }
}

This will:

• Install the package globally
• Run an interactive setup that asks for your API key
• Automatically configure VS Code settings with correct paths
• No manual configuration needed!

🎯 Method 2: Manual Configuration (Most Reliable)

1. Clone and build:

   git clone https://github.com/mohaimenhasan/mcp-weather-server.git
   cd mcp-weather-server
   npm run setup
   

2. Get your API key:

   • Visit OpenWeatherMap (free account)
   • Copy your API key

3. Add to VS Code:

   • Open VS Code
   • Press Ctrl+Shift+P (or Cmd+Shift+P on Mac)
   • Type "Preferences: Open User Settings (JSON)"
   • Add this to your settings:

   {
     "mcpServers": {
       "weather": {
         "command": "node",
         "args": ["/absolute/path/to/mcp-weather-server/dist/index.js"],
         "env": {
           "OPENWEATHER_API_KEY": "your_api_key_here"
         }
       }
     }

Error Handling

The server handles various error conditions:

• 404 Errors: City not found - suggests checking spelling
• 401 Errors: Invalid API key - prompts key configuration check
• Network Errors: Timeout or connection issues - suggests retrying
• API Limitations: Some features require premium OpenWeatherMap subscription

🆘 Troubleshooting

Common Issues

1. "Undefined input variable 'openweatherApiKey'" error:

   • This happens when VS Code can't resolve the input variable
   • Solution: Copy .vscode/settings.template.json to .vscode/settings.json and replace YOUR_API_KEY_HERE with your actual API key
   • Or create a .env file with OPENWEATHER_API_KEY=your_api_key_here

2. "API key is required" error:

   • Make sure you've set your API key in the environment variables or .env file
   • Check that your API key is valid and active at OpenWeatherMap

3. "Module not found" error:

   • Run npm run build to compile TypeScript
   • Ensure all dependencies are installed with npm install

4. MCP server not appearing in VS Code:

   • Check that the path in your MCP configuration is correct
   • Ensure the dist/index.js file exists after building
   • Restart VS Code after adding the server configuration

5. One-click install buttons not working:

   • If buttons open in browser instead of VS Code:
     • The MCP extension might not be installed or URL handler not registered
     • Use Method 1 (Manual Configuration) instead - it's more reliable
     • Run npm run config to get the exact configuration to copy
   • Make sure you have VS Code or VS Code Insiders installed
   • Ensure your project is built before attempting installation
