Example: Creating a Weather MCP Server

Create a weather API that Claude can use to get current weather conditions:

mcpgen
> Project name: weather-mcp
> Description: Weather information MCP server
> Data source: External API
> Tools: getWeather
> Deploy to: Vercel

This creates a complete MCP server with:

• TypeScript code for the weather API
• Environment configuration for API keys
• Ready-to-use integration with Claude
• One-click cloud deployment
• Automated test suite

Integration with Claude Desktop

Add to your Claude Desktop configuration:

// macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
// Windows: %APPDATA%\Claude\claude_desktop_config.json
{
  "mcpServers": {
    "your-mcp-name": {
      "command": "node",
      "args": ["/path/to/your-project/dist/main.js"],
      "env": {}
    }
  }
