Automated test suite for document-processor-mcp MCP server
Generated by KEN-MCP

INSTRUCTIONS FOR CLAUDE:
1. Run this test file immediately: python test.py
2. Fix any failing tests in server.py
3. Add domain-specific test cases based on the requirements
4. Ensure all tests pass before considering the MCP complete

Original Requirements:
Build an MCP that processes documents in multiple formats (PDF with forms, 
        scanned images, Word with track changes, Excel with formulas, PowerPoint, emails with 
        attachments), performs OCR with multiple language support, extracts structured data using 
        transformer-based NLP models, classifies documents using fine-tuned BERT, manages complex 
        document workflows with parallel approval chains, integrates with S3, Google Drive, and 
        SharePoint, sends templ...
