CI/CD Pipeline

The project includes a comprehensive GitHub Actions pipeline:

Lint and Format: Runs ruff for code formatting and linting
Test Suite: Runs tests across multiple Python versions and OS platforms
Security Scan: Performs security vulnerability scanning
Docker Build: Builds and tests Docker images
Auto-publish: Publishes to PyPI and Docker Hub on release

Required Secrets

For full CI/CD functionality, configure these GitHub secrets:

PYPI_API_TOKEN - PyPI authentication token
DOCKERHUB_USERNAME - Docker Hub username
DOCKERHUB_TOKEN - Docker Hub access token

Configuration

Environment Variables

LOG_LEVEL - Logging level (default: INFO)
PYTHONPATH - Python path for module resolution

Server Configuration

The server can be configured via the ServerConfig class in src/mcp_server/server.py:

config = ServerConfig()
config.max_connections = 200
config.timeout = 60

Docker Configuration

Multi-stage Build

The Dockerfile uses multi-stage builds for optimized image size:

Base stage: Sets up Python and system dependencies
Dependencies stage: Installs Python packages with uv
Runtime stage: Copies application code and runs the server

Health Checks

The container includes health checks to ensure the server is running correctly.
