# A2A Agent Examples
|
|
|
|
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](../../02-agents/background_responses.py).
|
|

## Examples
|
|
|
|
| File | Description |
|
|
|------|-------------|
|
|
| [`agent_with_a2a.py`](agent_with_a2a.py) | Demonstrates agent discovery, non-streaming and streaming responses using the A2A protocol. |
|
|
|
|
## Environment Variables
|
|
|
|
Make sure to set the following environment variables before running the example:
|
|
|
|
### Required
|
|
- `A2A_AGENT_HOST`: URL of a single A2A agent (for simple sample, e.g., `http://localhost:5001/`)
|
|
|
|
|
|
## Quick Testing with .NET A2A Servers
|
|
|
|
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`
|
|
|
|
### Run Python A2A Sample
|
|
```powershell
|
|
# Simple A2A sample (single agent)
|
|
uv run python agent_with_a2a.py
|
|
```
