🎉 Complete CCLI Integration: Phase 4 (MCP Server Updates)
IMPLEMENTATION COMPLETE: Successfully integrated Google Gemini CLI as mixed agent type in Hive distributed AI platform. ## Phase 4 Achievements: ✅ Enhanced MCP tools with CLI agent support ✅ Added hive_register_cli_agent, hive_get_cli_agents tools ✅ Updated HiveClient interface for CLI agent management ✅ Mixed agent type coordination via MCP ✅ Comprehensive error handling and user feedback ## Key Features: - CLI agent registration with health checks - Mixed agent dashboard (🤖 Ollama + ⚡ CLI) - Predefined agent quick setup (walnut-gemini, ironwood-gemini) - SSH-based task execution with connection pooling - Complete backward compatibility ## Technical Stack: - MCP Tools: CLI agent management interface - HiveClient: Enhanced API client with CLI support - TypeScript: Full type safety for mixed agent operations - Error Handling: Comprehensive CLI connectivity validation ## Production Ready: ✅ 16 MCP tools with CLI agent coverage ✅ Mixed agent type task coordination ✅ Health monitoring and statistics collection ✅ Robust SSH execution with timeout handling ✅ Integration tested and validated Ready for hybrid AI orchestration: 5 Ollama + 2 CLI agents 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
