Modular and Extensible Architecture

The core of the AutoGen architecture is its modularity, allowing developers to easily extend functionality by adding new agent roles or integrating with additional systems. This is achieved through a plug-and-play design, enabling quick adaptation to changing business needs.

A typical setup involves defining agent roles using frameworks like LangChain or AutoGen. These frameworks provide the necessary abstractions to manage agent behavior and interactions.

    from autogen.agents import AgentRole, AgentManager

    class ResearchAgent(AgentRole):
        def perform_task(self, data):
            # Implement task-specific logic
            pass

    manager = AgentManager()
    manager.register_agent(ResearchAgent())
    

Role-Based Access Control (RBAC)

Security is paramount in multi-agent systems. Implementing Role-Based Access Control (RBAC) ensures that each agent operates within its designated permissions, reducing the risk of unauthorized access to sensitive data. This is crucial for maintaining compliance and protecting data integrity.

    agent_permissions = {
        "ResearchAgent": ["read_public_data"],
        "DecisionAgent": ["read_sensitive_data"]
    }

    # AutoGen enforces permissions and logs unauthorized attempts
    

Integration with Existing Systems

Seamless integration with existing enterprise systems is achieved through standardized protocols and APIs. The architecture supports integration with vector databases like Pinecone or Weaviate for efficient data retrieval and storage.

    from pinecone import VectorDatabase

    db = VectorDatabase(api_key="your_api_key")
    db.connect()

    # Example of storing agent-generated vectors
    vectors = agent.generate_vectors(data)
    db.store(vectors)
    

MCP Protocol Implementation

The Message Communication Protocol (MCP) is implemented to facilitate reliable communication between agents. This protocol ensures that messages are delivered and processed efficiently, supporting multi-turn conversation handling and agent orchestration.

    from langgraph.mcp import MCPClient, MCPServer

    server = MCPServer(port=8080)
    client = MCPClient(server_address="localhost:8080")

    # Sending and receiving messages
    client.send_message("Hello, ResearchAgent!")
    response = server.receive_message()
    

Tool Calling Patterns and Schemas

Agents often need to call external tools or services to complete tasks. The architecture employs defined schemas and patterns for tool calling, ensuring consistency and reliability.

    from langchain.tools import ToolCaller

    tool_caller = ToolCaller(tool_name="DataAnalyzer")
    result = tool_caller.call_tool(input_data)
    

Memory Management and Multi-Turn Conversation Handling

Effective memory management is critical in multi-turn conversations. Using memory frameworks like ConversationBufferMemory, agents can maintain context and deliver coherent interactions.

    from langchain.memory import ConversationBufferMemory
    from langchain.agents import AgentExecutor

    memory = ConversationBufferMemory(
        memory_key="chat_history",
        return_messages=True
    )

    executor = AgentExecutor(memory=memory)
    

Agent Orchestration Patterns

Orchestrating multiple agents requires a structured approach to ensure coordination and task prioritization. The architecture supports orchestration patterns that facilitate efficient agent collaboration.

    from crewai.orchestration import AgentOrchestrator

    orchestrator = AgentOrchestrator()
