🏗️ Architecture

The project follows a modular architecture with separate managers for each GCP service:

• BigQuery (src/big_query.py): Data warehouse operations including query execution, data loading/exporting, job management, and cost estimation
• Cloud Logging (src/cloud_logging.py): Log management operations including reading/writing logs, managing buckets, sinks, exclusions, and metrics
• Cloud Storage (src/cloud_storage.py): Bucket and object management including CRUD operations, lifecycle management, and batch operations
• Compute Engine (src/compute_engine.py): Virtual machine management including instance lifecycle operations and zone management

Each manager class follows a consistent pattern:

• Constructor takes project_id and optional service_account_path
• Methods return dictionaries with operation results
• Comprehensive error handling and logging
• Support for both service account and default credential authentication

🧪 Testing

Run the test server:

python test_server.py

This will test all available MCP tools and verify their functionality.
