✅ MCP PROTOCOL COMPATIBILITY:
   • Server starts successfully
   • Handles JSON-RPC requests  
   • MCP initialization works
   • Protocol version 2024-11-05 supported

🔧 SERVER CAPABILITIES:
   • STDIO transport (most compatible)
   • HTTP transport (basic endpoints)
   • FastMCP 2.0 framework
   • Tool registration system
   • Resource system
   • Error handling

📊 POWERPOINT TOOLS READY:
   • extract_powerpoint_metadata
   • analyze_powerpoint_content
   • get_powerpoint_summary 
   • validate_powerpoint_file

🤖 AGENT INTEGRATION METHODS:
   1. STDIO Protocol (Recommended)
      - Works with any MCP client
      - Standard JSON-RPC over stdin/stdout
      - Compatible with most AI frameworks

   2. Direct Integration
      - Import your tools as Python modules
      - Call functions directly in Python agents
      - Full access to all capabilities

   3. HTTP Integration  
      - Basic REST endpoints available
      - Health and info endpoints working
      - Can be extended for custom agents

🎯 TESTING WITH REAL AGENTS:
   • Use MCP client libraries
   • Send JSON-RPC requests via STDIO
   • Tools are ready to analyze .pptx files
   • Error handling works correctly
