Learn how to implement agent-to-agent communication using the A2A Protocol
The A2A Protocol is available for multiple programming languages. Choose your preferred language to get started:
pip install a2a-protocolnpm install @a2a/protocolThe A2A Protocol is built on a few key concepts that you should understand before diving into implementation:
Agents are autonomous entities that can communicate with each other using the A2A Protocol. Each agent has a unique identity and can perform specific tasks.
Messages are the basic unit of communication between agents. They contain structured data that can be understood by both the sender and receiver.
The A2A Protocol defines the rules and formats for agent communication, ensuring interoperability between different implementations.
Let's create a simple agent that can send and receive messages using the A2A Protocol:
from a2a import Agent, Message
class MyAgent(Agent):
def __init__(self, name):
super().__init__(name)
def handle_message(self, message):
print(f"Received message: {message.content}")
return Message(
to=message.sender,
content=f"Hello from {self.name}!"
)
# Create and start the agent
agent = MyAgent("my-agent")
agent.start()const { Agent, Message } = require('@a2a/protocol');
class MyAgent extends Agent {
constructor(name) {
super(name);
}
async handleMessage(message) {
console.log(`Received message: ${message.content}`);
return new Message({
to: message.sender,
content: `Hello from ${this.name}!`
});
}
}
// Create and start the agent
const agent = new MyAgent('my-agent');
agent.start();Once you're comfortable with the basics, you can explore these advanced topics:
Learn how to implement complex message routing patterns and handle message delivery guarantees.
Implement secure communication between agents using encryption and authentication.
Design and implement scalable agent systems that can handle high message volumes.
