# BZZZ v2 MCP Integration Design
## GPT-4 Agent Framework for Distributed P2P Collaboration

### Executive Summary

This document outlines the comprehensive Model Context Protocol (MCP) integration for BZZZ v2, enabling GPT-4 agents to operate as first-class citizens within the distributed P2P task coordination system. The integration provides a bridge between OpenAI's GPT-4 models and the existing libp2p-based BZZZ infrastructure, creating a hybrid human-AI collaboration environment.

## 1. MCP Server Architecture

### 1.1 Core MCP Server Design

```typescript
interface BzzzMcpServer {
  // Protocol Operations
  tools: {
    bzzz_announce: ToolDefinition;
    bzzz_lookup: ToolDefinition;
    bzzz_get: ToolDefinition;
    bzzz_post: ToolDefinition;
    bzzz_thread: ToolDefinition;
    bzzz_subscribe: ToolDefinition;
  };
  
  // Agent Management
  agentLifecycle: AgentLifecycleManager;
  conversationManager: ConversationManager;
  costTracker: OpenAICostTracker;

### 2.2 Agent Lifecycle Management

#### Agent States and Transitions

```mermaid
stateDiagram-v2
    [*] --> Initializing
    Initializing --> Idle: Registration Complete
    Idle --> Active: Task Assigned
    Active --> Collaborating: Multi-agent Context
    Collaborating --> Active: Individual Work
    Active --> Idle: Task Complete
    Idle --> Terminating: Shutdown Signal
    Terminating --> [*]
    
    Active --> Escalating: Human Intervention Needed
    Escalating --> Active: Issue Resolved
    Escalating --> Terminating: Unresolvable Issue
```

#### Lifecycle Implementation

```go
type GPTAgent struct {
    ID           string
    Role         AgentRole
    State        AgentState
    Capabilities []string
    
    // OpenAI Configuration
    APIKey       string
    Model        string // gpt-4, gpt-4-turbo, etc.
    TokenLimit   int
    
    // BZZZ Integration

    Memory        *AgentMemory
    
    // Cost Management
    TokenUsage   *TokenUsageTracker
    CostLimits   *CostLimitConfig
}

func (agent *GPTAgent) Initialize() error {
    // Register with BZZZ network
    if err := agent.announcePresence(); err != nil {
        return err
    }
    
    // Subscribe to relevant topics
    if err := agent.subscribeToBzzzTopics(); err != nil {
        return err
    }
    
    // Initialize conversation memory
    agent.Memory = NewAgentMemory(agent.ID)
    
    agent.State = AgentStateIdle
    return nil
}

func (agent *GPTAgent) ProcessTask(task *repository.Task) error {
    agent.State = AgentStateActive
    
    // Create conversation context
    context := agent.buildTaskContext(task)
    
    // Check if collaboration is needed
    if agent.shouldCollaborate(task) {
        return agent.initiateCollaboration(task, context)
    }
    
    // Process individually
    return agent.processIndividualTask(task, context)
}
```

### 2.3 Context Sharing and Memory Management

#### Agent Memory System

```go
type AgentMemory struct {
    WorkingMemory    map[string]interface{}  // Current task context
    EpisodicMemory   []ConversationEpisode   // Past interactions
    SemanticMemory   *KnowledgeGraph         // Domain knowledge
    
    // Conversation History
    ThreadMemories   map[string]*ThreadMemory
    
    // Learning and Adaptation
    PerformanceFeedback []FeedbackEntry

## 3. Conversation Integration

### 3.1 Threaded Conversation Architecture

#### Thread Management System

```go
type ConversationManager struct {
    activeThreads   map[string]*ConversationThread
    threadIndex     *ThreadIndex
    summaryService  *ThreadSummaryService
    escalationRules *EscalationRuleEngine
}

type ConversationThread struct {
    ID           string
    Topic        string
    Participants []AgentParticipant
    Messages     []ThreadMessage
    State        ThreadState

#### Collaborative Review Pattern

```go
func (cm *ConversationManager) InitiateCollaborativeReview(
    task *repository.Task,
    requiredRoles []AgentRole,
) (*ConversationThread, error) {
    
    // Create thread for collaborative review
    thread := &ConversationThread{
        ID:    generateThreadID("review", task.Number),
        Topic: fmt.Sprintf("Collaborative Review: %s", task.Title),
        State: ThreadStateActive,
    }
    
    // Invite relevant agents
    for _, role := range requiredRoles {
        agents := cm.findAvailableAgents(role)
        for _, agent := range agents[:min(2, len(agents))] {
            thread.Participants = append(thread.Participants, AgentParticipant{
                AgentID: agent.ID,
                Role:    role,
                Status:  ParticipantStatusInvited,
            })
        }
    }
    
    // Set initial context
    thread.SharedContext = map[string]interface{}{
        "task_details": task,
        "review_criteria": getReviewCriteria(task),
        "deadline": calculateReviewDeadline(task),
    }
    
    // Start the conversation
    initialPrompt := cm.buildCollaborativeReviewPrompt(task, thread)
    if err := cm.postInitialMessage(thread, initialPrompt); err != nil {
        return nil, err
    }
    
    return thread, nil
}
```

#### Escalation Workflow Pattern

```go
type EscalationRuleEngine struct {
    rules []EscalationRule
}

type EscalationRule struct {
    Name        string
    Conditions  []EscalationCondition
    Actions     []EscalationAction
    Priority    int
}

type EscalationCondition struct {
    Type       string // "thread_duration", "consensus_failure", "error_rate"
    Threshold  interface{}
    Timeframe  time.Duration
}

func (ere *EscalationRuleEngine) CheckEscalation(thread *ConversationThread) []EscalationAction {
    var actions []EscalationAction
    
    for _, rule := range ere.rules {
        if ere.evaluateConditions(rule.Conditions, thread) {
            actions = append(actions, rule.Actions...)
        }
    }
    
    return actions
}

// Example escalation scenarios
var DefaultEscalationRules = []EscalationRule{
    {
        Name: "Long Running Thread",
        Conditions: []EscalationCondition{
            {Type: "thread_duration", Threshold: 2 * time.Hour, Timeframe: 0},
            {Type: "no_progress", Threshold: true, Timeframe: 30 * time.Minute},
        },
        Actions: []EscalationAction{
            {Type: "notify_human", Target: "project_manager"},
            {Type: "request_expert", Expertise: []string{"domain_expert"}},
        },
    },
    {
        Name: "Consensus Failure",
        Conditions: []EscalationCondition{
            {Type: "disagreement_count", Threshold: 3, Timeframe: 0},
            {Type: "no_resolution", Threshold: true, Timeframe: 1 * time.Hour},
        },
        Actions: []EscalationAction{
            {Type: "escalate_to_architect", Priority: "high"},
            {Type: "create_decision_thread", Participants: []string{"senior_architect"}},
        },
