MCP Integration for StateSet AI Agents

Overview

The Model Context Protocol (MCP) is an open standard that enables AI agents to seamlessly connect with external tools, services, and data sources. By integrating MCP into StateSet AI Agents, we enable them to send messages, interact with the StateSet Commerce Network, and perform complex operations across the blockchain ecosystem.

Introduction to MCP

MCP provides a standardized way for AI agents to:

Connect to external tools and services
Send and receive messages across different systems
Maintain context and state across interactions
Execute blockchain transactions on the StateSet Commerce Network

Key Benefits

Standardized Communication

Unified protocol for all agent-to-network interactions

Tool Integration

Seamless connection to StateSet modules and services

Context Persistence

Maintain agent state across sessions and transactions

StateSet Commerce Network Integration

Message Module Implementation

// proto/stateset/message/v1/message.proto
syntax = "proto3";
package stateset.message.v1;

import "google/protobuf/timestamp.proto";
import "cosmos/base/v1beta1/coin.proto";

// Message represents a message sent through the StateSet network
message Message {
  string id = 1;
  string sender = 2;
  string recipient = 3;
  string content = 4;
  string message_type = 5;
  string metadata = 6; // JSON string
  google.protobuf.Timestamp created_at = 7;
  MessageStatus status = 8;
}

enum MessageStatus {
  MESSAGE_STATUS_UNSPECIFIED = 0;
  MESSAGE_STATUS_PENDING = 1;
  MESSAGE_STATUS_DELIVERED = 2;
  MESSAGE_STATUS_READ = 3;
  MESSAGE_STATUS_FAILED = 4;
}

// MsgSendMessage defines a message for sending a message through the network
message MsgSendMessage {
  string sender = 1;
  string recipient = 2;
  string content = 3;
  string message_type = 4;
  string metadata = 5;
}

  cosmos.base.query.v1beta1.PageResponse pagination = 2;
}

// Msg service for message transactions
service Msg {
  rpc SendMessage(MsgSendMessage) returns (MsgSendMessageResponse);
}

Message Protocol

Message Types and Formats

// types/message-protocol.ts

export enum MessageType {
  ORDER = 'order',
  PAYMENT = 'payment',
  INVENTORY = 'inventory',
  GENERAL = 'general',
  SYSTEM = 'system',
  AGENT_HANDOFF = 'agent_handoff',
  WORKFLOW_TRIGGER = 'workflow_trigger'
}

export interface BaseMessage {
  id: string;
  sender: string;
  recipient: string;
  messageType: MessageType;
  timestamp: string;
  metadata: Record<string, any>;
}

export interface OrderMessage extends BaseMessage {
  messageType: MessageType.ORDER;
  content: {
    orderId: string;
    action: 'create' | 'update' | 'cancel' | 'fulfill';
    orderData?: any;
  };
}

export interface PaymentMessage extends BaseMessage {
  messageType: MessageType.PAYMENT;
  content: {
    paymentId: string;
    amount: string;
    currency: string;
    status: 'pending' | 'completed' | 'failed';
  };
}

export interface AgentHandoffMessage extends BaseMessage {
  messageType: MessageType.AGENT_HANDOFF;
  content: {
    fromAgent: string;
    toAgent: string;
    context: any;
    reason: string;
  };
}

export interface WorkflowTriggerMessage extends BaseMessage {
  messageType: MessageType.WORKFLOW_TRIGGER;
  content: {
    workflowId: string;
    triggerType: string;
    parameters: Record<string, any>;
  };
}

Security Considerations

1. Authentication and Authorization

// security/mcp-auth.ts

export class MCPAuthProvider {
  private validatedAgents: Map<string, AgentCredentials> = new Map();
  
  async authenticateAgent(agentId: string, signature: string): Promise<boolean> {
    // Verify agent signature using public key
    const agent = await this.getAgentCredentials(agentId);
    if (!agent) return false;
    
    return this.verifySignature(agentId, signature, agent.publicKey);
  }
  
  async authorizeAction(agentId: string, action: string, resource: string): Promise<boolean> {
    const permissions = await this.getAgentPermissions(agentId);
    
    return permissions.some(p => 
      p.action === action && 
      (p.resource === '*' || p.resource === resource)
    );
  }
  
  private async getAgentCredentials(agentId: string): Promise<AgentCredentials | null> {
    // Fetch from StateSet network or cache
    return this.validatedAgents.get(agentId) || null;
  }
  
  private async getAgentPermissions(agentId: string): Promise<Permission[]> {
    // Query permissions from the network
    const agent = await this.statesetClient.agents.get(agentId);
    return agent.permissions || [];
  }
  
  private verifySignature(agentId: string, signature: string, publicKey: string): boolean {
    // Implement signature verification
    return true; // Placeholder
  }
}

interface AgentCredentials {
  agentId: string;
  publicKey: string;
  permissions: Permission[];
}

interface Permission {
  action: string;
  resource: string;
}

2. Message Encryption

// security/message-encryption.ts

export class MessageEncryption {
  async encryptMessage(message: any, recipientPublicKey: string): Promise<string> {
    // Implement end-to-end encryption for sensitive messages
    // Using recipient's public key
    return JSON.stringify(message); // Placeholder
  }
  
  async decryptMessage(encryptedMessage: string, privateKey: string): Promise<any> {
    // Decrypt message using private key
    return JSON.parse(encryptedMessage); // Placeholder
  }
}

Testing and Deployment

1. Unit Tests

// tests/mcp-server.test.ts

import { describe, it, expect } from 'vitest';
import { StateSetMCPServer } from '../src/stateset-mcp-server';

describe('StateSet MCP Server', () => {
  let server: StateSetMCPServer;
  
  beforeEach(() => {
    server = new StateSetMCPServer({
      apiKey: 'test-key',
      networkEndpoint: 'http://localhost:26657',
      chainId: 'test-chain'
    });
  });
  
  it('should list available tools', async () => {
    const tools = await server.listTools();
    
    expect(tools).toContain('send_message');
    expect(tools).toContain('create_order');
    expect(tools).toContain('query_network_state');
    expect(tools).toContain('execute_transaction');
  });
  
  it('should send a message successfully', async () => {
    const result = await server.handleSendMessage({
      recipient: 'agent-123',
      message: 'Test message',
      messageType: 'general',
      metadata: { test: true }
    });
    
    expect(result.isError).toBeFalsy();
    expect(result.metadata.transactionHash).toBeDefined();
  });
  
  it('should handle network errors gracefully', async () => {
    // Simulate network error
    server.statesetClient = null;
    
    const result = await server.handleSendMessage({
      recipient: 'agent-123',
      message: 'Test message',
      messageType: 'general'
    });
    
    expect(result.isError).toBeTruthy();
    expect(result.content[0].text).toContain('Failed to send message');
  });
});

Best Practices

1. Error Handling

class MCPErrorHandler {
  static handleError(error: any, context: string): MCPError {
    if (error.code === 'NETWORK_ERROR') {
      return new MCPError(
        'Network communication failed',
        'NETWORK_ERROR',
        { originalError: error, context }
      );
    }
    
    if (error.code === 'UNAUTHORIZED') {
      return new MCPError(
        'Agent not authorized for this action',
        'AUTH_ERROR',
        { originalError: error, context }
      );
    }
    
    return new MCPError(
      'An unexpected error occurred',
      'UNKNOWN_ERROR',
      { originalError: error, context }
    );
  }
}

class MCPError extends Error {
  constructor(
    message: string,
    public code: string,
    public details: any
  ) {
    super(message);
    this.name = 'MCPError';
  }
}

2. Rate Limiting

class MCPRateLimiter {
  private requests: Map<string, number[]> = new Map();
  
  constructor(
    private maxRequests: number = 100,
    private windowMs: number = 60000 // 1 minute
  ) {}
  
  async checkLimit(agentId: string): Promise<boolean> {
    const now = Date.now();
    const requests = this.requests.get(agentId) || [];
    
    // Remove old requests outside the window
    const validRequests = requests.filter(time => now - time < this.windowMs);
    
    if (validRequests.length >= this.maxRequests) {
      return false;
    }
    
    validRequests.push(now);
    this.requests.set(agentId, validRequests);
    
    return true;
  }
}

3. Monitoring and Observability

class MCPMonitor {
  private metrics: Map<string, any> = new Map();
  
  recordToolCall(toolName: string, agentId: string, duration: number, success: boolean) {
    const key = `tool_call_${toolName}`;
    const current = this.metrics.get(key) || {
      total: 0,
      success: 0,
      failed: 0,
      avgDuration: 0
    };
    
    current.total++;
    if (success) current.success++;
    else current.failed++;
    
    current.avgDuration = (current.avgDuration * (current.total - 1) + duration) / current.total;
    
    this.metrics.set(key, current);
    
    // Send to monitoring service
    this.sendToMonitoring({
      metric: 'mcp.tool_call',
      tags: { tool: toolName, agent: agentId, success: success.toString() },
      value: duration
    });
  }
  
  private sendToMonitoring(metric: any) {
    // Implement sending to Prometheus, DataDog, etc.
    console.log('Metric:', metric);
  }
}

Conclusion

By implementing MCP (Model Context Protocol) for StateSet AI Agents, we enable:

Standardized Communication: All agents can communicate with the StateSet Commerce Network using a unified protocol
Enhanced Capabilities: Agents can perform complex operations like creating orders, processing payments, and managing inventory
Scalability: New tools and services can be easily added to the MCP server
Security: Built-in authentication, authorization, and encryption ensure secure communications
Interoperability: Agents can work together and hand off tasks seamlessly

This implementation provides a robust foundation for AI agents to interact with the StateSet Commerce Network, enabling autonomous commerce operations at scale.
