Use A2A without GOOGLE_API_KEY and Gemini

[romairi]

Hi everyone,

I’d like to open a discussion about using the A2A protocol without relying on Google or Gemini ADKs.

In my case, I work with other models like AWS Bedrock and OpenAI, since I only have subscriptions to these services. Our company does not allow access to Gemini, so I’m looking for ways to fully utilize the A2A protocol without depending on Google’s generative features.

Is it possible to implement the A2A protocol independently and still get all of its core functionality? I’m especially interested in using it for agent-to-agent communication, task delegation, and tool execution — but powered by non-Google LLMs.

If anyone has experience building A2A-compatible systems without Google ADK, I’d love to hear how you approached it and what tools/libraries you used.

Thanks in advance!

A2A protocol does not have any dependency on Gemini or ADK. You can use any framework with any LLM to expose your agents as A2A servers.

Examples for agents built with different frameworks and LLMs are here - https://github.com/a2aproject/a2a-samples/tree/main/samples/python/agents
