A2A Protocol Integration with KaibanJS
Explore the seamless integration of the A2A Protocol with KaibanJS, demonstrating how AI agents can communicate and collaborate using standardized protocols for universal interoperability.
Revolutionizing Agent-to-Agent Communication
The A2A Protocol represents a groundbreaking advancement in AI agent communication, enabling seamless interoperability between agents regardless of their underlying technology stack. Built as an open standard, it allows agents to work together effortlessly, fostering collaboration across different platforms and frameworks.
KaibanJS's integration with the A2A Protocol brings this revolutionary capability to your multi-agent applications, providing enterprise-grade security, multi-modal communication support, and universal interoperability that scales with your business needs.
System Architecture & Implementation
The integration combines the power of KaibanJS multi-agent orchestration with the standardized A2A Protocol for universal agent communication.
Server Architecture
- ✓Express.js Server: Built with A2A Protocol SDK for standardized agent communication
- ✓Agent Executor: Implements A2A AgentExecutor interface for protocol compliance
- ✓Agent Card: Defines agent capabilities and communication protocols
- ✓KaibanJS Team: Orchestrates multi-agent workflows with web search and summarization
Client Architecture
- ✓React Application: Built with Vite for modern development and fast builds
- ✓A2A Client: Connects to server using Agent Card discovery protocol
- ✓Real-time Streaming: Live updates of agent workflow logs and status
- ✓State Management: Zustand for efficient client-side state handling
KaibanJS A2A Integration Architecture
The integration uses a custom AgentExecutor that bridges KaibanJS multi-agent workflows with the A2A Protocol standard.
KaibanjsAgentExecutor Implementation
A custom class that implements the A2A Protocol's AgentExecutor interface, serving as the bridge between A2A requests and KaibanJS team workflows.
Key Responsibilities:
- • Extracts user queries from A2A message parts
- • Creates and manages KaibanJS team instances
- • Publishes real-time status updates via EventBus
- • Streams workflow logs as A2A artifacts
- • Handles task completion and error states
Real-time Event Streaming
The integration provides live updates by subscribing to KaibanJS team store changes and converting them to A2A Protocol events.
Event Types Streamed:
- • TaskStatusUpdate: Individual task progress
- • AgentStatusUpdate: Agent activity states
- • WorkflowStatusUpdate: Overall workflow progress
- • Artifact Updates: Final results and outputs
Integration Flow
A2A Request
Client sends message via A2A Protocol to server endpoint
Query Extraction
AgentExecutor extracts text query from message parts
Team Execution
KaibanJS team processes query with real-time log streaming
Result Delivery
Final results sent as A2A artifacts with completion status
Implementation Details
Technical implementation of the A2A Protocol integration with KaibanJS multi-agent system.
Agent Card Discovery
The server exposes agent capabilities via the standardized Agent Card endpoint:
GET /.well-known/agent-card.jsonThis enables automatic discovery of agent capabilities and communication protocols.
Message Routing
Messages are routed through the A2A Protocol standard:
POST /messageEnsures reliable delivery and protocol compliance across different agent platforms.
Multi-Agent Workflow
KaibanJS orchestrates complex workflows:
- • Scout Agent: Web search using Tavily API
- • Writer Agent: Content summarization
- • Team Coordination: Workflow orchestration
Real-time Streaming
Live updates are streamed to the client:
- • Agent status updates
- • Workflow progress logs
- • Final results via A2A artifacts
