Build the project: ```bash npm run build ``` ### Claude Desktop Configuration 1. Create/Edit `%AppData%/Claude/claude_desktop_config.json`: ```json { "mcpServers": { "Gemini Data Analysis": { "command": "node", "args": ["path/to/gemini-data-analysis-email-generator/dist/index.js"], "cwd": "path/to/gemini-data-analysis-email-generator", "env": { "GEMINI_API_KEY": "your_api_key_here", "NODEMAILER_EMAIL": "your.email@gmail.com", "NODEMAILER_PASSWORD": "your_app_password_here" } } } } ``` 2. Restart Claude Desktop ## 📊 Using the Tools ### Data Analysis with EDA and AI ```json { "name": "analyze-data", "arguments": { "fileData": "base64_encoded_file_content", "fileName": "data.xlsx", "analysisType": "detailed", "outputDir": "./analysis_results" } } ``` ### Email Sending with AI Subject Generation ```json { "name": "send-email", "arguments": { "to": "recipient@example.com", "subjectPrompt": "Create a professional subject line for a business report", "text": "Hello! This is the plain text version of our email.", "html": "<h1>Hello!</h1><p>This is the <b>HTML</b> version of our email.</p>", "images": [ { "name": "chart.png", "data": "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAA..." } ] } } ``` ### Thinking Generation ```json { "name": "generate-thinking", "arguments": { "prompt": "Analyze the market trends for Q1 2024", "outputDir": "./thinking_output" } } ``` ## 📁 Output Structure ``` output/ ├── analysis/ │ ├── plots/ │ │ ├── column1_histogram_[timestamp].html │ │ └── column2_histogram_[timestamp].html │ ├── analysis_[timestamp].txt │ └── report_[timestamp].html ├── thinking/ │ └── gemini_thinking_[timestamp].txt └── emails/ └── email_log_[timestamp].txt ``` ## 🛠️ Development ### Available Scripts - `npm run build`: Compile TypeScript to JavaScript - `npm run start`: Start the MCP server - `npm run dev`: Run in development mode with ts-node ### Environment Variables - `GEMINI_API_KEY`: Your Google Gemini API key - `NODEMAILER_EMAIL`: Your email address for sending emails - `NODEMAILER_PASSWORD`: Your email app password (for Gmail, use an app password) ## 🔒 Security Notes - Store your API keys securely - Don't share your `.env` file - For Gmail, use app passwords instead of your main account password - Be careful with the content of emails sent through the system - Never include sensitive or personal information in email examples ## 🐛 Troubleshooting ### Common Issues 1. **API Key Error** - Verify `.env` file exists - Check API key validity - Ensure proper environment loading 2. **Claude Desktop Connection** - Verify config.json syntax - Check file paths in config - Restart Claude Desktop 3. **Email Sending Issues** - Check that NODEMAILER_EMAIL and NODEMAILER_PASSWORD are set correctly - For Gmail, ensure you've created an app password - Verify that less secure app access is enabled for non-Gmail providers - Check recipient email address format 4. **Data Analysis Issues** - Ensure file format is supported (.xlsx, .xls, .csv) - Check file encoding (UTF-8 recommended) - Verify file size is within limits - Ensure numeric columns are properly formatted ### Debug Mode Add `DEBUG=true` to your `.env` file for verbose logging: ```env GEMINI_API_KEY=your_key_here DEBUG=true ``` ## 📚 API Reference ### Data Analysis Tool ```typescript interface AnalyzeDataParams { fileData: string; // Base64 encoded file content fileName: string; // File name (must be .xlsx, .xls, or .csv) analysisType: 'basic' | 'detailed'; // Analysis type outputDir?: string; // Optional output directory } ``` ### Email Sending Tool ```typescript interface SendEmailParams { to: string; // Recipient email address subjectPrompt: string; // Prompt for Gemini to generate email subject text: string; // Plain text version of email html?: string; // HTML version of email (optional) images?: { // Optional images to attach name: string; // Image filename data: string; // Base64 encoded image data }[]; } ``` ### Thinking Generation Tool ```typescript interface GenerateThinkingParams { prompt: string; // Analysis prompt outputDir?: string; // Optional output directory } ``` ## 👨‍💻 Author **Falah G.
