agent-framework-a2a

What it is and what it does

agent-framework-a2a is a protocol bridge that implements the A2A (Agent-to-Agent) standard for agent-framework-core. It provides two main components: A2AAgent, a client that connects to remote A2A-compliant agents, and A2AExecutor, which exposes local agents to external clients via the A2A protocol. This enables agents to interoperate with agents running on different platforms or languages.

The package is designed for scenarios where you need to integrate multiple agents across different services or deployment contexts. It handles message routing, protocol translation, and response streaming. The description emphasizes that production deployments must add authentication and authorization independently—the package itself focuses on protocol wiring, not security enforcement.

Use it for:

• Connect a local agent to a remote A2A-compliant agent running on another platform or service.
• Host a local agent so it can be accessed by external A2A clients or other agent systems.
• Build multi-agent systems where agents communicate across different languages or deployment environments.
• Stream responses and handle real-time interaction between heterogeneous agent implementations.
• Integrate with existing A2A ecosystems that expect A2A protocol compliance.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Enables communication with remote A2A-compliant agents and allows local agents to be hosted and accessed via the standardized A2A protocol.

Yes, if you need to integrate agents with A2A-compliant systems or expose them via the A2A protocol. The low install friction, active maintenance, and permissive license make it straightforward to add. However, this is a beta release, so expect potential API changes. You must implement your own authentication and authorization for production use.

Install

Installing agent-framework-a2a

Before you install

Low install friction with only 2 runtime dependencies. Active maintenance with a recent release 15 days old and substantial repository activity (12803 stars). Beta status indicates ongoing development.

License in practice

MIT license (permissive) means you can use, modify, and distribute this package with minimal restrictions, provided you include the license notice.

Quickstart

pip install agent-framework-a2a --pre

from agent_framework.a2a import A2AAgent
a2a_agent = A2AAgent(url="http://remote-agent/a2a")
response = await a2a_agent.run("Hello!")

Requires Python 3.10 or later. The run() method is async and must be called within an async context.

Verify before relying

• Whether the referenced examples in the description are available and current in the repository.
• Performance characteristics and latency overhead of the A2A protocol bridge for typical workloads.
• Compatibility details with specific A2A-compliant implementations beyond agent-framework-core and a2a-sdk.
