Prerequisites
Before you begin, ensure you have the following prerequisites:
- .NET 8.0 SDK or later
- Access to the A2A agent host service
Note: These samples need to be run against a valid A2A server. If no A2A server is available, they can be run against the echo-agent that can be spun up locally by following the guidelines at: https://github.com/a2aproject/a2a-dotnet/blob/main/samples/AgentServer/README.md
Set the following environment variables:
$env:A2A_AGENT_HOST="https://your-a2a-agent-host" # Replace with your A2A agent host endpoint
Advanced scenario
This method can be used to create AI agents for A2A agents whose hosts support the Direct Configuration / Private Discovery discovery mechanism.
using A2A;
using Microsoft.Extensions.AI.Agents;
using Microsoft.Extensions.AI.Agents.A2A;
// Create an A2AClient pointing to your `echo` A2A agent endpoint
A2AClient a2aClient = new(new Uri("https://your-a2a-agent-host/echo"));
// Create an AIAgent from the A2AClient
AIAgent agent = a2aClient.GetAIAgent();
// Run the agent
AgentRunResponse response = await agent.RunAsync("Tell me a joke about a pirate.");
Console.WriteLine(response);
