SwarmAgentSDK

The SwarmAgentSDK provides a simple way for agents to connect to and interact with the Agent Swarm Protocol orchestrator.

Installation

npm install @agent-swarm/agent-sdk

Basic Usage

const { SwarmAgentSDK } = require('@agent-swarm/agent-sdk');

// Create a new agent
const agent = new SwarmAgentSDK({
  name: 'MyAgent',
  description: 'A simple agent built with SwarmAgentSDK',
  capabilities: ['text-processing']
});

// Connect to the orchestrator
agent.connect()
  .then(() => {
    console.log('Connected to orchestrator');
  })
  .catch(error => {
    console.error('Error:', error.message);
  });

// Register a task handler
agent.onMessage('text-processing', async (taskData, metadata) => {
  console.log('Received text processing task:', taskData);
  
  // Process the text
  const processedText = taskData.text.toUpperCase();
  
  // Send task notifications to update the client on progress
  await agent.sendTaskNotification({
    taskId: metadata.taskId,
    notificationType: 'progress',
    message: 'Starting text processing...',
    data: { progress: 0 }
  });
  
  // Simulate some processing time
  await new Promise(resolve => setTimeout(resolve, 1000));
  
  await agent.sendTaskNotification({
    taskId: metadata.taskId,
    notificationType: 'progress',
    message: 'Processing text...',
    data: { progress: 50 }
  });
  
  await new Promise(resolve => setTimeout(resolve, 1000));
  
  await agent.sendTaskNotification({
    taskId: metadata.taskId,
    notificationType: 'progress',
    message: 'Finalizing results...',
    data: { progress: 90 }
  });
  
  // Return the result
  return {
    processedText
  };
});

// Listen for events
agent.on('error', (error) => {
  console.error('Agent error:', error.message);
});

Configuration Options

The SwarmAgentSDK constructor accepts a configuration object with the following properties:

Key Features

Task Handling

• onMessage(taskType, handler): Register a handler for a specific task type
• onMessage('*', handler): Register a default handler for all task types
• sendTaskResult(taskId, result): Send a task result back to the client

Task Notifications

• sendTaskNotification(notification): Send a notification to inform clients about task progress
• onNotification(handler): Register a handler for receiving notifications from the orchestrator

Agent Communication

• getAgentList(filters): Get a list of all available agents
• executeAgentTask(targetAgentName, taskType, taskData): Ask another agent to execute a task

MCP Integration

• getMCPServers(filters): Get a list of available MCP servers
• getMCPTools(serverId): Get a list of tools available on an MCP server
• executeMCPTool(serverId, toolName, parameters): Execute an MCP tool
• executeTool(toolName, parameters): Simplified method to execute an MCP tool

Connection Management

• connect(): Connect to the orchestrator
• disconnect(): Disconnect from the orchestrator

Service Communication

• executeServiceTask(serviceId, functionName, params, options): Execute a task on a service
  • Allows agents to call functions provided by services with real-time notification updates
  • The options.onNotification callback receives progress updates during execution
• getServiceList(filters): Get a list of available services

Events

The SDK emits the following events:

• connected: Emitted when connected to the orchestrator
• registered: Emitted when the agent is registered with the orchestrator
• disconnected: Emitted when disconnected from the orchestrator
• error: Emitted when an error occurs
• message: Emitted for all received messages
• task: Emitted when a task is received
