Security

• Certificate files are excluded from version control via .gitignore
• Never commit .env files or certificates to repositories
• Use environment variables for sensitive configuration
• Certificates should be properly secured with appropriate file permissions

Troubleshooting

Connection Issues

1. Certificate errors: Verify certificates are in PEM format and readable
2. Authentication fails: Check QLIK_USER_DIRECTORY and QLIK_USER_ID settings
3. Timeout errors: Increase WEBSOCKET_TIMEOUT in .env
4. App not found: Verify app ID and user permissions in QMC

MCP Issues

1. Server won't start: Check Python version (3.10+ required)
2. Tool not found: Restart Claude Desktop after configuration changes
3. No response: Check server logs for errors

Development

Running Tests

The project uses pytest exclusively for professional-grade testing with clear separation between unit and integration tests.

Setup Test Environment

# Install test dependencies (automatically handled by UV)
uv sync  # Installs both main and dev dependencies including pytest

# Configure test environment for integration tests
cp .env.test.example .env.test
# Edit .env.test with your Qlik server details (when available)

Pytest Testing Commands

# Run all tests
uv run pytest

# Run with verbose output
uv run pytest -v

# Run only unit tests (no Qlik server required - perfect for development)
uv run pytest -m unit

# Run integration tests (requires Qlik server connection)
uv run pytest -m integration

# Run with coverage report
uv run pytest --cov=src --cov-report=html

# Run specific test file
uv run pytest tests/test_mcp_tool.py

# Run specific test function
uv run pytest tests/test_mcp_tool.py::test_get_app_measures_mock

Test Categories

The test suite uses pytest markers for clear organization:

• @pytest.mark.unit: Fast tests that don't require external dependencies
• @pytest.mark.integration: Tests requiring live Qlik Sense server connection
• @pytest.mark.slow: Long-running tests (can be excluded with -m "not slow")

Pro Tip: Use uv run pytest -m unit during development for fast feedback loops, then run integration tests when you have Qlik server access.

uv run pytest tests/test_fields.py -v             # Field and table information
uv run pytest tests/test_sheets.py -v             # Sheet metadata
uv run pytest tests/test_dimensions.py -v         # Dimension analysis
uv run pytest tests/test_script.py -v             # Script retrieval and analysis
uv run pytest tests/test_data_sources.py -v       # Data source lineage
uv run pytest tests/test_binary_extraction.py -v  # BINARY LOAD extraction
uv run pytest tests/test_vizlib_container.py -v   # VizlibContainer functionality
uv run pytest tests/test_both_tools.py -v         # Multiple tools together

# Debug Qlik client directly
uv run python -m src.qlik_client

See tests/README.md for comprehensive testing documentation.

Code Quality & Formatting

The project maintains high code quality standards with automated tooling:

# Run Ruff linting and formatting
uv run ruff check                    # Check for style and quality issues
uv run ruff check --fix              # Auto-fix issues where possible
uv run ruff format                   # Format code according to standards

# The project is configured with:
# - pyproject.toml: Ruff configuration for consistent code style
# - Automatic import sorting and code formatting
# - Integration with development workflow

Continuous Integration (CI/CD)

The project includes a comprehensive GitHub Actions workflow (.github/workflows/test.yml) that automatically:

🔄 Automated Testing:

• Runs on every push to main and develop branches
• Executes on all pull requests
• Matrix testing across multiple Python versions (3.10, 3.11, 3.12, 3.13)
• Separate unit test and integration test execution

🛠️ Quality Assurance:

• UV dependency management and caching
• Ruff linting and formatting verification
• Pytest execution with coverage reporting
• Test result reporting and failure notifications

🚀 Manual Triggers:

• Workflow can be manually triggered via GitHub Actions UI
• Optional integration test execution (when Qlik server access is available)

The CI/CD pipeline ensures code quality and prevents regressions, making the project reliable for production use.

Adding New Tools

To add more Qlik tools:

1. Define a Pydantic model in tools.py for parameter validation with Field annotations
2. Implement the tool function in tools.py
3. Register the tool in server.py using @mcp.tool() accepting the Pydantic model
4. FastMCP automatically generates schemas from Pydantic models

Tool Definitions

The server provides 9 comprehensive tools for complete Qlik Sense analysis. See the main tools table above for complete details and parameters.

Limitations

Current implementation considerations:

• Single app connection at a time
• No retry logic for failed connections
• Basic error handling
• No caching of results
• Sequential processing only
• Minimal logging

Future Enhancements

The project has achieved a modern, production-ready foundation. Potential enhancements:

📈 Scalability & Performance:

• Connection pooling for multiple concurrent app connections
• Intelligent caching of frequently accessed data
• WebSocket reconnection handling with retry logic

🔧 Additional Functionality:

• Tools for additional Qlik objects (bookmarks, stories, etc.)
• Advanced filtering and pagination for large datasets
• Bulk operations for enterprise-scale deployments

🔍 Observability & Monitoring:

• Structured logging with configurable levels
• Performance metrics and monitoring endpoints
• Distributed tracing for complex operations

Note: The core development infrastructure (UV, Ruff, Pytest, GitHub Actions) is already enterprise-ready, providing a solid foundation for these future enhancements.
