hko_mcp

👋 This project is in active development, PRs are welcomed 🙏🙇‍♀️

hko_mcp is a personal ("pet") project developed by louis as a learning exercise and technical playground. It focuses on integrating with the Hong Kong Observatory (HKO) and potentially other MCP (possibly a custom or third-party service) APIs. The project serves as a hands-on exploration of modern TypeScript tooling and testing practices.

Technical Stack

tools included and configured:

• TypeScript 5.7
• ESM
• ESLint with some initial rules recommendation
• Vitest for fast unit testing and code coverage
• Type definitions for Node.js
• Prettier to enforce consistent code style
• NPM scripts for common operations
• EditorConfig for consistent coding style
• Reproducible environments thanks to Volta
• Example configuration for GitHub Actions
• Simple example of TypeScript code and unit test
