⚙️ Configuration

Environment Variables

Customize the behavior using environment variables:

# Set embedding model
set MCP_MODEL_NAME=all-mpnet-base-v2

# Set chunk size for text processing
set MCP_CHUNK_SIZE=200

# Set chunk overlap
set MCP_OVERLAP=50

# Set environment
set MCP_ENVIRONMENT=production

Configuration File

The system uses config.py for advanced configuration. You can modify:

• Embedding model settings
• Text chunking parameters
• File paths for index and metadata
• Server configuration

Fallback Systems

The CLI includes multiple fallback systems for maximum reliability:

• MCP Server Fallback: Falls back to simple implementation if full MCP unavailable
• Text Search Fallback: Uses basic text matching if semantic search fails
• Export Fallback: Falls back to text format if PDF/HTML generation fails
• Directory Creation: Automatically creates notes directory if missing

🔧 Troubleshooting

Common Issues

1. Import Errors:

# Check dependencies
pip install -r requirements.txt

# Verify Python path
python -c "import sys; print(sys.path)"

2. Search Not Working:

# Rebuild index
python mcp_cli_fixed.py rebuild-index

# Check if notes directory exists
dir notes\*.md

3. JSON Serialization Errors (FIXED!):

# This now works automatically
python mcp_cli_fixed.py list-notes --format json

4. Export Functionality (NEW!):

# Export search results
python mcp_cli_fixed.py search "query" --export results.json --format json

5. Server Not Starting:

# Check port availability
netstat -an | findstr :8181

# Try different port
python mcp_cli_fixed.py server --port 8080

6. Rebuild Index Issues (FIXED!):

# Now supports all arguments
python mcp_cli_fixed.py rebuild-index --chunk-size 300 --overlap 100

Debug Mode

Enable debug output for troubleshooting:

# Run with verbose output
python mcp_cli_fixed.py search "test" --limit 3

Recent Fixes

• ✅ JSON datetime serialization - Fixed datetime objects in JSON output
• ✅ Search export functionality - Added --export argument to search command
• ✅ Rebuild-index arguments - Fixed argument parsing and directory handling
• ✅ Server threading issues - Fixed import and threading problems
• ✅ Syntax errors - All f-string and compilation errors fixed
• ✅ Fallback systems - Multiple fallback implementations for reliability
