## 📝 Notes & Decisions
### Technical Decisions
- **2025-07-18**: Chose FastMCP over manual MCP implementation for better OAuth support
- **2025-07-18**: Selected Google Cloud Run over Cloudflare Workers for consistency with team standards
- **2025-07-18**: Decided on Python 3.11+ for better type hinting and async support
- **2025-07-19**: Adopted uv for dependency management for faster installs and better lock files
- **2025-07-19**: Used httpx for async HTTP requests in OAuth implementation
- **2025-07-19**: Implemented Firestore-based token storage for multi-user support
- **2025-07-19**: Built comprehensive API client with Pydantic models for type safety
- **2025-07-19**: Implemented rate limiting (5 req/sec) and exponential backoff retry logic
- **2025-07-19**: Used editable package install to resolve PYTHONPATH issues
- **2025-07-19**: Implemented HTTP transport using FastMCP's native Streamable-HTTP support
- **2025-07-21**: Adopted Authlib for standard OAuth2 implementation with AsyncOAuth2Client
