Agent-to-Agent (A2A) protocol support for inter-agent communication.
Main Classes
A2AAgent- Client to connect to remote A2A-compliant agents.A2AExecutor- Bridge to expose Agent Framework agents via the A2A protocol.A2AServiceSessionId- Typed durable A2A continuation state shape stored inAgentSession.service_session_id.A2AAgentSession- Deprecated compatibility session wrapper; preferAgentSession+A2AServiceSessionId.
Usage
A2AAgent (Client)
from agent_framework.a2a import A2AAgent
# Connect to a remote A2A agent
a2a_agent = A2AAgent(url="http://remote-agent/a2a")
response = await a2a_agent.run("Hello!")
A2AExecutor (Server/Bridge)
from agent_framework.a2a import A2AExecutor
from a2a.server.request_handlers import DefaultRequestHandler
from a2a.server.routes import create_agent_card_routes, create_jsonrpc_routes
from a2a.server.tasks import InMemoryTaskStore
from starlette.applications import Starlette
# Create an A2A executor for your agent
executor = A2AExecutor(agent=my_agent)
# Set up the request handler (agent_card is required)
request_handler = DefaultRequestHandler(
agent_executor=executor,
task_store=InMemoryTaskStore(),
agent_card=my_agent_card,
)
# Build a Starlette app with A2A routes
app = Starlette(
routes=[
*create_agent_card_routes(my_agent_card),
*create_jsonrpc_routes(request_handler, "/"),
]
)
