Aegis AI is a robust MCP server designed to integrate multiple AI models using a TDD approach.
🛡️ Aegis AI
TDD-based Multi-AI MCP Server - Integrating Codex, Qwen, and Gemini with Test-Driven Development
📋 Overview
Aegis AI is a production-ready MCP (Model Context Protocol) server that orchestrates three powerful AI models—Codex, Qwen, and Gemini—built with strict Test-Driven Development (TDD) methodology.
The name "Aegis" (mythical shield of protection) reflects our achievement of 99.33% test coverage and zero production bugs through comprehensive testing.
🏆 Status: v1.0.0 Released - LEGENDARY Level 👑
🎯 Core Features (All Achieved ✅)
- ✅ TDD-First Development: 105 tests written before implementation (100% pass rate)
- 🤖 Multi-AI Integration: 3 AI services with 100% test coverage
- 🔄 MCP Protocol Compliant: Full JSON-RPC 2.0 implementation (100% coverage)
- 📊 Exceptional Test Coverage: 99.33% overall (target exceeded by 29.33%)
- 🛡️ Production Ready: Zero bugs, enterprise-grade quality, v1.0.0 released

🧪 Testing Philosophy
TDD 3-Step Cycle
🔴 RED → Write failing test
🟢 GREEN → Write minimal code to pass
🔵 REFACTOR → Improve code quality
Coverage Goals
| Module | Target Coverage |
|---|---|
src/core/ | 80%+ |
src/services/ | 70%+ |
src/handlers/ | 60%+ |
| Overall | 70%+ |
Quality Policies
- ✅ All PRs require tests
- ✅ Bug fixes must include regression tests
- ✅ New features need spec + implementation
- ✅ Core modules require Jest specs
