+This file provides guidance to Claude Code (claude.ai/code) when working with the MCP Office Tools codebase.
+
+## Project Overview
+
+MCP Office Tools is a FastMCP server that provides comprehensive Microsoft Office document processing capabilities including text extraction, image extraction, metadata extraction, and format detection. The server supports Word (.docx, .doc), Excel (.xlsx, .xls), PowerPoint (.pptx, .ppt), and CSV files with intelligent method selection and automatic fallbacks.
+
+## Development Commands

+
+## Architecture
+
+### Core Components
+
+- **`src/mcp_office_tools/server.py`**: Main server implementation with all Office processing tools
+- **`src/mcp_office_tools/utils/`**: Utility modules for validation, caching, and file detection
+- **FastMCP Framework**: Uses FastMCP for MCP protocol implementation
+- **Multi-library approach**: Integrates python-docx, openpyxl, python-pptx, pandas, and legacy format handlers
+
+### Tool Categories
+
+1. **Universal Tools**: Work across all Office formats
+   - `extract_text` - Intelligent text extraction
+   - `extract_images` - Image extraction with filtering
+   - `extract_metadata` - Document metadata extraction
+   - `detect_office_format` - Format detection and analysis
+   - `analyze_document_health` - Document integrity checking
+
+2. **Format-Specific Processing**: Specialized handlers for Word, Excel, PowerPoint
+3. **Legacy Format Support**: OLE Compound Document processing for .doc, .xls, .ppt
+4. **URL Processing**: Direct URL document processing with caching
+
+### Intelligent Fallbacks
+
+The server implements smart fallback mechanisms:
+- Text extraction uses multiple libraries in order of preference
+- Automatic format detection determines best processing method
+- Legacy format support with graceful degradation
+- Comprehensive error handling with helpful diagnostics
+
+### Dependencies Management
+
+Core dependencies:
+- **python-docx**: Modern Word document processing
+- **openpyxl**: Excel XLSX file processing

+## Development Notes
+
+### Testing Strategy
+- Unit tests for each tool with mocked Office libraries
+- Test fixtures for consistent document simulation
+- Error handling tests for all major failure modes
+- Format detection and validation testing
+- URL processing and caching tests
+
+### Tool Implementation Pattern
+All tools follow this pattern:
+1. Validate and resolve file path (including URL downloads)
+2. Detect format and validate document integrity
+3. Try primary method with intelligent selection based on format
+4. Implement fallbacks where applicable
+5. Return structured results with metadata
+6. Include timing information and method used
+7. Provide helpful error messages with troubleshooting hints
+
+### Format Support Matrix
+- **Modern formats** (.docx, .xlsx, .pptx): Full feature support
+- **Legacy formats** (.doc, .xls, .ppt): Basic extraction with graceful degradation
+- **CSV files**: Specialized pandas-based processing

+
+### URL and Caching Support
+- HTTPS URL processing with validation
+- Intelligent caching system (1-hour default)
+- Temporary file management with automatic cleanup
+- Security headers and content validation
+
+### MCP Integration
+Tools are registered using FastMCP decorators and follow MCP protocol standards for:

+### **URL Processing**
+Process Office documents directly from URLs:
+
+```python
+# Direct URL processing
+url_doc = "https://example.com/document.docx"
+content = await extract_text(url_doc)
+
+# Automatic caching (1-hour default)
+cached_content = await extract_text(url_doc)  # Uses cache
+```
+
+### **Format Detection**
+Intelligent format detection and validation:
+
+```python
+# Comprehensive format analysis
+format_info = await detect_office_format("unknown_file.office")
+
+# Returns:
+# - Format name and category
+# - MIME type validation
+# - Legacy vs modern classification
+# - Processing recommendations
+```
+
+### **Document Health Analysis**
+Comprehensive document integrity checking:
+
+```python
+# Health assessment
+health = await analyze_document_health("suspicious_file.docx")
+
+# Returns:
+# - Health score (1-10)
+# - Validation results
+# - Corruption detection
+# - Processing recommendations
+```
+
+## 📈 Performance & Compatibility

+
+## 🤝 Integration with MCP PDF Tools
+
+MCP Office Tools is designed as a perfect companion to [MCP PDF Tools](https://github.com/mcp-pdf-tools/mcp-pdf-tools):
+
+```python
+# Unified document processing workflow
+pdf_content = await pdf_tools.extract_text("document.pdf")
+docx_content = await office_tools.extract_text("document.docx")
+
+# Cross-format analysis
+pdf_metadata = await pdf_tools.extract_metadata("document.pdf")
+docx_metadata = await office_tools.extract_metadata("document.docx")
+```
+
+## 📋 Supported Formats
+
+```python
+# Get all supported formats
+formats = await get_supported_formats()
+
+# Returns comprehensive format information:
+# - 15+ file extensions
+# - MIME type mappings
+# - Category classifications
+# - Processing capabilities
+```
+
+## 🔒 Security & Privacy
+
+- **No data collection**: Documents processed locally
+- **Temporary files**: Automatic cleanup after processing
+- **URL validation**: Secure HTTPS-only downloads
+- **Memory management**: Efficient processing of large files
+
+## 📝 License
+
+MIT License - see [LICENSE](LICENSE) file for details.
+
+## 🚀 Coming Soon
