hko-mcp - MCP Servers Directory

👋 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
