📝 Update README: 40 tools, v2.0.7 table features, token management

PROBLEM:
Table extraction from large PDFs was exceeding MCP's 25,000 token limit,
causing "response too large" errors. A 5-page PDF with large tables
generated 59,005 tokens, more than double the allowed limit.

SOLUTION:
Added flexible table data limiting with two new parameters:
- max_rows_per_table: Limit rows returned per table (prevents overflow)
- summary_only: Return only metadata without table data

IMPLEMENTATION:
1. Added new parameters to extract_tables() method signature
2. Created _process_table_data() helper for consistent limiting logic
3. Updated all 3 extraction methods (Camelot, pdfplumber, Tabula)
4. Enhanced table metadata with truncation tracking:
   - total_rows: Full row count from PDF
   - rows_returned: Actual rows in response (after limiting)
   - rows_truncated: Number of rows omitted (if limited)

USAGE EXAMPLES:
# Summary mode - metadata only (smallest response)
extract_tables(pdf_path, pages="1-5", summary_only=True)

# Limited data - first 100 rows per table
extract_tables(pdf_path, pages="1-5", max_rows_per_table=100)

# Full data (default behavior, may overflow on large tables)
extract_tables(pdf_path, pages="1-5")

BENEFITS:
- Prevents MCP token overflow errors
- Maintains backward compatibility (new params are optional)
- Clear guidance through metadata (shows when truncation occurred)
- Flexible - users choose between summary/limited/full modes

FILES MODIFIED:
- src/mcp_pdf/mixins_official/table_extraction.py (all changes)
- src/mcp_pdf/server.py (version bump to 2.0.7)

+# 🔧 Local Development Guide for MCP PDF
+
+This guide shows how to test MCP PDF locally during development before publishing to PyPI.
+
+## 📋 Prerequisites
+
+- Python 3.10+
+- uv package manager
+- Claude Desktop app
+- Git repository cloned locally
+
+## 🚀 Quick Start for Local Testing
+
+### 1. Clone and Setup
+
+```bash
+# Clone the repository
+git clone https://github.com/rsp2k/mcp-pdf.git
+cd mcp-pdf
+
+# Install dependencies
+uv sync --dev
+
+# Verify installation
+uv run python -c "from mcp_pdf.server import create_server; print('✅ MCP PDF loads successfully')"
+```
+
+### 2. Add MCP Server to Claude Desktop
+
+#### For Production Use (PyPI Installation)
+
+Install the published version from PyPI:
+
+```bash
+# For personal use across all projects
+claude mcp add -s local pdf-tools uvx mcp-pdf
+
+# For project-specific use (isolated to current directory)
+claude mcp add -s project pdf-tools uvx mcp-pdf
+```
+
+#### For Local Development (Source Installation)
+
+When developing MCP PDF itself, use the local source:
+
+```bash
+# For development from local source
+claude mcp add -s project pdf-tools-dev uv -- --directory /path/to/mcp-pdf-tools run mcp-pdf
+```
+
+Or if you're in the mcp-pdf directory:
+
+```bash
+# Development server from current directory
+claude mcp add -s project pdf-tools-dev uv -- --directory . run mcp-pdf
+```
+
+### 3. Alternative: Manual Server Testing
+
+You can also run the server manually for debugging:
+
+```bash
+# Run the MCP server directly
+uv run mcp-pdf
+
+# Or run with specific FastMCP options
+uv run python -m mcp_pdf.server
+```
+
+### 4. Test Core Functionality
+
+Once connected to Claude Code, test these key features:
+
+#### Basic PDF Processing
+```
+"Extract text from this PDF file: /path/to/test.pdf"
+"Get metadata from this PDF: /path/to/document.pdf"
+"Check if this PDF is scanned: /path/to/scan.pdf"
+```
+
+#### Security Features
+```
+"Try to extract text from a very large PDF"
+"Process a PDF with 2000 pages" (should be limited to 1000)
+```
+
+#### Advanced Features
+```
+"Extract tables from this PDF: /path/to/tables.pdf"
+"Convert this PDF to markdown: /path/to/document.pdf"
+"Add annotations to this PDF: /path/to/target.pdf"
+```
+
+## 🔒 Security Testing
+
+Verify the security hardening works:
+
+### File Size Limits
+- Try processing a PDF larger than 100MB
+- Should see: "PDF file too large: X bytes > 104857600"
+
+### Page Count Limits  
+- Try processing a PDF with >1000 pages
+- Should see: "PDF too large for processing: X pages > 1000"
+
+### Path Traversal Protection
+- Test with malicious paths like `../../../etc/passwd`
+- Should be blocked with security error
+
+### JSON Input Validation
+- Large JSON inputs (>10KB) should be rejected
+- Malformed JSON should return clean error messages
+
+## 🐛 Debugging
+
+### Enable Debug Logging
+```bash
+export DEBUG=true
+uv run mcp-pdf
+```
+
+### Check Security Functions
+```bash
+# Test security validation functions
+uv run python test_security_features.py
+
+# Run integration tests
+uv run python test_integration.py
+```
+
+### Verify Package Structure
+```bash
+# Check package builds correctly
+uv build
+
+# Verify package metadata
+uv run twine check dist/*
+```
+
+## 📊 Testing Checklist
+
+Before publishing, verify:
+
+- [ ] All 23 PDF tools work correctly
+- [ ] Security limits are enforced (file size, page count)
+- [ ] Error messages are clean and helpful  
+- [ ] No sensitive information leaked in errors
+- [ ] Path traversal protection works
+- [ ] JSON input validation works
+- [ ] Memory limits prevent crashes
+- [ ] CLI command `mcp-pdf` works
+- [ ] Package imports correctly: `from mcp_pdf.server import create_server`
+
+## 🚀 Publishing Pipeline
+
+Once local testing passes:
+
+1. **Version Bump**: Update version in `pyproject.toml`
+2. **Build**: `uv build`  
+3. **Test Upload**: `uv run twine upload --repository testpypi dist/*`
+4. **Test Install**: `pip install -i https://test.pypi.org/simple/ mcp-pdf`
+5. **Production Upload**: `uv run twine upload dist/*`
+
+## 🔧 Development Commands
+
+```bash
+# Format code
+uv run black src/ tests/
+
+# Lint code  
+uv run ruff check src/ tests/
+
+# Run tests
+uv run pytest
+
+# Security scan
+uv run pip-audit
+
+# Build package
+uv build
+
+# Install editable for development
+pip install -e .  # (in a venv)
+```
+
+## 🆘 Troubleshooting
+
+### "Module not found" errors
+- Ensure you're in the right directory
+- Run `uv sync` to install dependencies
+- Check Python path with `uv run python -c "import sys; print(sys.path)"`
+
+### MCP server won't start
+- Check that all system dependencies are installed (tesseract, java, ghostscript)
+- Verify with: `uv run python examples/verify_installation.py`
+
+### Security tests fail
+- Run `uv run python test_security_features.py -v` for detailed output
+- Check that security constants are properly set
+
+This setup allows for rapid development and testing without polluting your system Python or needing to publish to PyPI for every change.

+
+## MCPMixin Base Class Features
+
+### Auto-Registration
+```python
+class TextExtractionMixin(MCPMixin):
+    @mcp_tool(name="extract_text", description="Extract text from PDF")
+    async def extract_text(self, pdf_path: str) -> Dict[str, Any]:
+        # Implementation automatically registered as MCP tool
+        pass
+```
+
+### Permission System
+```python
+def get_required_permissions(self) -> List[str]:
+    return ["read_files", "ocr_processing"]
+```
+
+### Component Discovery
+```python
+def get_registered_components(self) -> Dict[str, Any]:
+    return {
+        "mixin": "TextExtraction",
+        "tools": ["extract_text", "ocr_pdf", "is_scanned_pdf"],
+        "resources": [],
+        "prompts": [],
+        "permissions_required": ["read_files", "ocr_processing"]
+    }
+```
+
+## Implementation Examples
+
+### Text Extraction Mixin
+```python
+from .base import MCPMixin, mcp_tool
+from ..security import validate_pdf_path, sanitize_error_message
+
+class TextExtractionMixin(MCPMixin):
+    def get_mixin_name(self) -> str:
+        return "TextExtraction"
+
+    def get_required_permissions(self) -> List[str]:
+        return ["read_files", "ocr_processing"]
+
+    @mcp_tool(name="extract_text", description="Extract text with intelligent method selection")
+    async def extract_text(self, pdf_path: str, method: str = "auto") -> Dict[str, Any]:
+        try:
+            validated_path = await validate_pdf_path(pdf_path)
+            # Implementation here...
+            return {"success": True, "text": extracted_text}
+        except Exception as e:
+            return {"success": False, "error": sanitize_error_message(str(e))}
+```
+
+### Server Composition
+```python
+class PDFToolsServer:
+    def __init__(self):
+        self.mcp = FastMCP("pdf-tools")
+        self.mixins = []
+
+        # Initialize mixins
+        mixin_classes = [
+            TextExtractionMixin,
+            TableExtractionMixin,
+            DocumentAnalysisMixin,
+            # ... other mixins
+        ]
+
+        for mixin_class in mixin_classes:
+            mixin = mixin_class(self.mcp, **self.config)
+            self.mixins.append(mixin)
+```
+
+## Migration Strategy
+
+### Phase 1: Setup Infrastructure
+1. Create `mixins/` directory structure
+2. Implement `MCPMixin` base class
+3. Extract security utilities to `security.py`
+4. Set up testing framework
+
+### Phase 2: Extract First Mixin
+1. Start with `TextExtractionMixin`
+2. Move text extraction tools from server.py
+3. Update imports and dependencies
+4. Test thoroughly
+
+### Phase 3: Iterative Migration
+1. Extract one mixin at a time
+2. Test each migration independently
+3. Update server.py to use new mixins
+4. Maintain backward compatibility
+
+### Phase 4: Cleanup and Optimization
+1. Remove original server.py code
+2. Optimize mixin interactions
+3. Add advanced features (progressive disclosure, etc.)
+4. Final testing and documentation
+
+## Testing Strategy
+
+### Unit Testing Per Mixin
+```python
+class TestTextExtractionMixin:
+    def setup_method(self):
+        self.mcp = FastMCP("test")
+        self.mixin = TextExtractionMixin(self.mcp)
+
+    @pytest.mark.asyncio
+    async def test_extract_text_validation(self):
+        result = await self.mixin.extract_text("")
+        assert not result["success"]
+```
+
+### Integration Testing
+```python
+class TestMixinComposition:
+    def test_no_tool_name_conflicts(self):
+        # Ensure no tools have conflicting names
+        pass
+
+    def test_comprehensive_coverage(self):
+        # Ensure all original tools are covered
+        pass
+```
+
+### Auto-Discovery Testing
+```python
+def test_mixin_auto_registration(self):
+    mixin = TextExtractionMixin(mcp)
+    components = mixin.get_registered_components()
+    assert "extract_text" in components["tools"]
+```
+
+## Advanced Patterns
+
+### Progressive Tool Disclosure
+```python
+class SecureTextExtractionMixin(TextExtractionMixin):
+    def __init__(self, mcp_server, permissions=None, **kwargs):
+        self.user_permissions = permissions or []
+        super().__init__(mcp_server, **kwargs)
+
+    def _should_auto_register_tool(self, name: str, method: Callable) -> bool:
+        # Only register tools user has permission for
+        required_perms = self._get_tool_permissions(name)
+        return all(perm in self.user_permissions for perm in required_perms)
+```
+
+### Dynamic Tool Visibility
+```python
+@mcp_tool(name="advanced_ocr", description="Advanced OCR with ML")
+async def advanced_ocr(self, pdf_path: str) -> Dict[str, Any]:
+    if not self._check_premium_features():
+        return {"error": "Premium feature not available"}
+    # Implementation...
+```
+
+### Bulk Operations
+```python
+class BulkProcessingMixin(MCPMixin):
+    @mcp_tool(name="bulk_extract_text", description="Process multiple PDFs")
+    async def bulk_extract_text(self, pdf_paths: List[str]) -> Dict[str, Any]:
+        # Leverage other mixins for bulk operations
+        pass
+```
+
+## Performance Considerations
+
+### Lazy Loading
+- Mixins only initialize when first used
+- Heavy dependencies loaded on-demand
+- Configurable mixin selection
+
+### Memory Management
+- Clear separation prevents memory leaks
+- Each mixin manages its own resources
+- Proper cleanup in error cases
+
+### Startup Time
+- Fast initialization with auto-registration
+- Parallel mixin initialization possible
+- Tool registration is cached
+
+## Security Enhancements
+
+### Centralized Validation
+```python
+# security.py
+async def validate_pdf_path(pdf_path: str) -> Path:
+    # Single source of truth for PDF validation
+    pass
+
+def sanitize_error_message(error_msg: str) -> str:
+    # Consistent error sanitization
+    pass
+```
+
+### Permission-Based Access
+```python
+class SecureMixin(MCPMixin):
+    def get_required_permissions(self) -> List[str]:
+        return ["read_files", "specific_operation"]
+
+    def _check_permissions(self, required: List[str]) -> bool:
+        return all(perm in self.user_permissions for perm in required)
+```
+
+## Deployment Configurations
+
+### Development Server
+```python
+# All mixins enabled, debug logging
+server = PDFToolsServer(
+    mixins="all",
+    debug=True,
+    security_mode="relaxed"
+)
+```
+
+### Production Server
+```python
+# Selected mixins, strict security
+server = PDFToolsServer(
+    mixins=["TextExtraction", "TableExtraction"],
+    security_mode="strict",
+    rate_limiting=True
+)
+```
+
+### Specialized Deployment
+```python
+# OCR-only server
+server = PDFToolsServer(
+    mixins=["TextExtraction"],
+    tools=["ocr_pdf", "is_scanned_pdf"],
+    gpu_acceleration=True
+)
+```
+
+## Comparison with Current Approach
+
+| Aspect | Current FastMCP | MCPMixin Pattern |
+|--------|----------------|------------------|
+| **Organization** | Single 6500+ line file | Modular mixins (~200-500 lines each) |
+| **Testability** | Hard to test individual tools | Easy isolated testing |
+| **Maintainability** | Difficult to navigate/modify | Clear separation of concerns |
+| **Extensibility** | Add to monolithic file | Create new mixin |
+| **Security** | Scattered validation | Centralized security utilities |
+| **Performance** | All tools loaded always | Lazy loading possible |
+| **Reusability** | Monolithic server only | Mixins reusable across projects |
+| **Debugging** | Hard to isolate issues | Clear component boundaries |
+
+## Conclusion
+
+The MCPMixin pattern transforms large, monolithic FastMCP servers into maintainable, testable, and scalable architectures. While it requires initial refactoring effort, the long-term benefits in maintainability, testability, and extensibility make it worthwhile for any server with 10+ tools.
+
+The pattern is particularly valuable for:
+- **Complex servers** with multiple tool categories
+- **Team development** where different developers work on different domains
+- **Production deployments** requiring security and reliability
+- **Long-term maintenance** and feature evolution
+
+For your MCP PDF server with 24+ tools, the MCPMixin pattern would provide significant improvements in code organization, testing capabilities, and future extensibility.

+    validate_pdf_path,
+    validate_output_path,
+    sanitize_error_message,
+    validate_pages_parameter
+)
+```
+
+Benefits:
+- ✅ **Consistent security**: All mixins use same validation
+- ✅ **Easier auditing**: Single file to review
+- ✅ **Better maintenance**: Fix security issues in one place

+- **📦 Auto-Registration**: Perfect tool discovery and routing
+- **🔧 FastMCP Integration**: Seamless compatibility
+- **⚡ ImageProcessingMixin**: COMPLETED! (`extract_images`, `pdf_to_markdown`)
+- **📝 TextExtractionMixin**: COMPLETED! All 3 tools working (`extract_text`, `ocr_pdf`, `is_scanned_pdf`)
+- **📊 TableExtractionMixin**: COMPLETED! Table extraction with intelligent fallbacks (`extract_tables`)
+- **🔍 DocumentAnalysisMixin**: COMPLETED! All 3 tools working (`extract_metadata`, `get_document_structure`, `analyze_pdf_health`)

+- **🔧 DocumentAssemblyMixin**: COMPLETED! All 3 tools working (`merge_pdfs`, `split_pdf`, `reorder_pdf_pages`)
+- **🎨 AnnotationsMixin**: COMPLETED! All 4 tools working (`add_sticky_notes`, `add_highlights`, `add_video_notes`, `extract_all_annotations`)
+
+### 📋 **SCOPE DISCOVERY: Original Server Has 41 Tools (Not 24!)**
+**Major Discovery**: The original monolithic server contains 41 tools, significantly more than the 24 originally estimated. Our current modular implementation covers the core 20 tools representing the most commonly used PDF operations.
+
+## 🎯 Migration Strategy
+
+### **Phase 1: Template Pattern Established** ✅
+- [x] Create working ImageProcessingMixin as template
+- [x] Establish correct async/await pattern
+- [x] Publish v1.2.0 with working architecture
+- [x] Validate stub implementations work perfectly
+
+### **Phase 2: Fix Existing Mixins**
+**Priority**: High (these have partial implementations)
+
+#### **TextExtractionMixin**
+- **Issue**: Helper methods incorrectly marked as async
+- **Fix Strategy**: Copy working implementation from original server
+- **Tools**: `extract_text`, `ocr_pdf`, `is_scanned_pdf`
+- **Effort**: Medium (complex text processing logic)
+
+#### **TableExtractionMixin**
+- **Issue**: Helper methods incorrectly marked as async
+- **Fix Strategy**: Copy working implementation from original server
+- **Tools**: `extract_tables`
+- **Effort**: Medium (multiple library fallbacks)
+
+### **Phase 3: Implement Remaining Mixins**
+**Priority**: Medium (these have working stubs)
+
+#### **DocumentAnalysisMixin**
+- **Tools**: `extract_metadata`, `get_document_structure`, `analyze_pdf_health`
+- **Template**: Use ImageProcessingMixin pattern
+- **Effort**: Low (mostly metadata extraction)
+
+#### **FormManagementMixin**
+- **Tools**: `create_form_pdf`, `extract_form_data`, `fill_form_pdf`
+- **Template**: Use ImageProcessingMixin pattern
+- **Effort**: Medium (complex form handling)
+
+#### **DocumentAssemblyMixin**
+- **Tools**: `merge_pdfs`, `split_pdf`, `reorder_pdf_pages`
+- **Template**: Use ImageProcessingMixin pattern
+- **Effort**: Low (straightforward PDF manipulation)
+
+#### **AnnotationsMixin**
+- **Tools**: `add_sticky_notes`, `add_highlights`, `add_video_notes`, `extract_all_annotations`
+- **Template**: Use ImageProcessingMixin pattern
+- **Effort**: Medium (annotation positioning logic)
+
+## 📋 **Correct Implementation Pattern**
+
+Based on the successful ImageProcessingMixin, all implementations should follow this pattern:
+
+```python
+class MyMixin(MCPMixin):
+    @mcp_tool(name="my_tool", description="My tool description")
+    async def my_tool(self, pdf_path: str, **kwargs) -> Dict[str, Any]:
+        """Main tool function - MUST be async for MCP compatibility"""
+        try:
+            # 1. Validate inputs (await security functions)
+            path = await validate_pdf_path(pdf_path)
+            parsed_pages = parse_pages_parameter(pages)  # No await - sync function
+
+            # 2. All PDF processing is synchronous
+            doc = fitz.open(str(path))
+            result = self._process_pdf(doc, parsed_pages)  # No await - sync helper
+            doc.close()
+
+            # 3. Return structured response
+            return {"success": True, "result": result}
+
+        except Exception as e:
+            error_msg = sanitize_error_message(str(e))
+            return {"success": False, "error": error_msg}
+
+    def _process_pdf(self, doc, pages):
+        """Helper methods MUST be synchronous - no async keyword"""
+        # All PDF processing happens here synchronously
+        return processed_data
+```
+
+## 🚀 **Implementation Steps**
+
+### **Step 1: Copy Working Code**
+For each mixin, copy the corresponding working function from `src/mcp_pdf/server.py`:
+
+```bash
+# Example: Extract working extract_text function
+grep -A 100 "async def extract_text" src/mcp_pdf/server.py
+```
+
+### **Step 2: Adapt to Mixin Pattern**
+1. Add `@mcp_tool` decorator
+2. Ensure main function is `async def`
+3. Make all helper methods `def` (synchronous)
+4. Use centralized security functions from `security.py`
+
+### **Step 3: Update Imports**
+1. Remove from `stubs.py`
+2. Add to respective mixin file
+3. Update `mixins/__init__.py`
+
+### **Step 4: Test and Validate**
+1. Test with MCP server
+2. Verify all tool functionality
+3. Ensure no regressions
+
+## 🎯 **Success Metrics**
