Sample Code

This code is used to demonstrate A2A capabilities as the spec progresses.\ Samples are divided into 3 sub directories:

• Common
  Common code that all sample agents and apps use to speak A2A over HTTP.

• Agents
  Sample agents written in multiple frameworks that perform example tasks with tools. These all use the common A2AServer.

• Hosts
  Host applications that use the A2AClient. Includes a CLI which shows simple task completion with a single agent, a mesop web application that can speak to multiple agents, and an orchestrator agent that delegates tasks to one of multiple remote A2A agents.

Prerequisites

• Python 3.13 or higher
• UV

Running the Samples

Run one (or more) agent A2A server and one of the host applications.

The following example will run the langgraph agent with the python CLI host:

1. Navigate to the agent directory:

   cd samples/python/agents/langgraph

2. Run an agent:

   uv run .

3. In another terminal, navigate to the CLI directory:

   cd samples/python/hosts/cli

4. Run the example client

   uv run .
