This folder contains examples demonstrating how to create and use agents with the A2A (Agent2Agent) protocol from the agent_framework package to communicate with remote A2A agents.
By default the A2AAgent waits for the remote agent to finish before returning (background=False), so long-running A2A tasks are handled transparently. For advanced scenarios where you need to poll or resubscribe to in-progress tasks using continuation tokens, see the background responses sample.

agent_with_a2a.py |
Demonstrates agent discovery, non-streaming and streaming responses using the A2A protocol. |
Make sure to set the following environment variables before running the example:
A2A_AGENT_HOST: URL of a single A2A agent (for simple sample, e.g.,http://localhost:5001/)
For quick testing and demonstration, you can use the pre-built .NET A2A servers from this repository:
Quick Testing Reference: Use the .NET A2A Client Server sample at:
..\agent-framework\dotnet\samples\05-end-to-end\A2AClientServer
# Simple A2A sample (single agent)
uv run python agent_with_a2a.py
