timezone.utc which is available in Python 3.10+.
Fixed ImportError: cannot import name 'UTC' from 'datetime'

- Added comprehensive logging showing exact URLs to access the MCP server
- Display localhost instead of 0.0.0.0 for better usability
- Show MCP endpoint, transport type, and status endpoint information
- Added visual separators to make server info stand out in logs
This helps users understand exactly how to connect to the MCP server
and troubleshoot connection issues.

- Changed hardcoded default in schema.py from gpt-4o to gpt-4.1
- Fixed default config path to look in config/config.yaml relative to mcp_server directory
- This ensures the server uses gpt-4.1 as the default model everywhere

- Fix API key detection: Remove hardcoded OpenAI checks, let factories handle provider-specific validation
- Fix .env file loading: Search for .env in mcp_server directory first
- Change default transport to SSE for broader compatibility (was stdio)
- Add proper error handling with warnings for failed client initialization
- Model already defaults to gpt-4o as requested
These changes ensure the MCP server properly loads API keys from .env files
and creates the appropriate LLM/embedder clients based on configuration.

This is a major refactoring of the MCP Server to support multiple providers
through a YAML-based configuration system with factory pattern implementation.
## Key Changes
### Architecture Improvements
- Modular configuration system with YAML-based settings
- Factory pattern for LLM, Embedder, and Database providers
- Support for multiple database backends (Neo4j, FalkorDB, KuzuDB)
- Clean separation of concerns with dedicated service modules
### Provider Support
- **LLM**: OpenAI, Anthropic, Gemini, Groq
- **Embedders**: OpenAI, Voyage, Gemini, Anthropic, Sentence Transformers
- **Databases**: Neo4j, FalkorDB, KuzuDB (new default)
- Azure OpenAI support with AD authentication
### Configuration
- YAML configuration with environment variable expansion
- CLI argument overrides for runtime configuration
- Multiple pre-configured Docker Compose setups
- Proper boolean handling in environment variables
### Testing & CI
- Comprehensive test suite with unit and integration tests
- GitHub Actions workflows for linting and testing
- Multi-database testing support
### Docker Support
- Updated Docker images with multi-stage builds
- Database-specific docker-compose configurations
- Persistent volume support for all databases
### Bug Fixes
- Fixed KuzuDB connectivity checks
- Corrected Docker command paths
- Improved error handling and logging
