🎯 Phase 4 Completion Summary

Phase: MCP Server Updates for Mixed Agent Support
Status: ✅ COMPLETE
Date: July 10, 2025

📊 Phase 4 Achievements

✅ Enhanced MCP Tools

1. New CLI Agent Registration Tools

• hive_register_cli_agent - Register individual CLI agents with full configuration
• hive_get_cli_agents - List and manage CLI agents specifically
• hive_register_predefined_cli_agents - Quick setup for walnut-gemini and ironwood-gemini

2. Enhanced Agent Enumeration

• Updated all tool schemas to include CLI agent types:
  • cli_gemini - Direct Gemini CLI integration
  • general_ai - General-purpose AI capabilities
  • reasoning - Advanced reasoning and analysis
• Backward compatible with existing Ollama agent types

3. Improved Agent Visualization

• Enhanced hive_get_agents tool groups agents by type:
  • 🤖 Ollama Agents - API-based agents via HTTP
  • ⚡ CLI Agents - SSH-based CLI execution
• Visual distinction with icons and clear labeling
• Health status and capacity information for both agent types

✅ Updated HiveClient Interface

Enhanced Agent Interface

export interface Agent {
  id: string;
  endpoint: string;
  model: string;
  specialty: string;
  status: 'available' | 'busy' | 'offline';
  current_tasks: number;
  max_concurrent: number;
  agent_type?: 'ollama' | 'cli';        // NEW: Agent type distinction
  cli_config?: {                        // NEW: CLI-specific configuration
    host?: string;
    node_version?: string;
    model?: string;
    specialization?: string;
    max_concurrent?: number;
    command_timeout?: number;
    ssh_timeout?: number;
    agent_type?: string;
  };
}

New CLI Agent Methods

• getCliAgents() - Retrieve CLI agents specifically
• registerCliAgent() - Register new CLI agent with validation
• registerPredefinedCliAgents() - Bulk register walnut/ironwood agents
• healthCheckCliAgent() - CLI agent health monitoring
• getCliAgentStatistics() - Performance metrics collection
• unregisterCliAgent() - Clean agent removal

✅ Tool Integration

CLI Agent Registration Flow

        Available for Task Assignment ✅

Mixed Agent Coordination

• Task routing automatically selects appropriate agent type
• Unified task execution interface supports both CLI and Ollama agents
• Health monitoring works across all agent types
• Statistics collection covers mixed agent environments

✅ Enhanced Tool Descriptions

Registration Tool Example

{
  name: 'hive_register_cli_agent',
  description: 'Register a new CLI-based AI agent (e.g., Gemini CLI) in the Hive cluster',
  inputSchema: {
    properties: {
      id: { type: 'string', description: 'Unique CLI agent identifier' },
      host: { type: 'string', description: 'SSH hostname (e.g., walnut, ironwood)' },
      node_version: { type: 'string', description: 'Node.js version (e.g., v22.14.0)' },
      model: { type: 'string', description: 'Model name (e.g., gemini-2.5-pro)' },
      specialization: { 
        type: 'string', 
        enum: ['general_ai', 'reasoning', 'code_analysis', 'documentation', 'testing'],
        description: 'CLI agent specialization'
      }
    }
  }
}
