Quick Use

Use it first, then decide how deep to go

This block should tell both the user and the agent what to copy, install, and apply first.

  1. Browse the full directory: github.com/ai-boost/awesome-a2a
  2. Find your category (SDKs, frameworks, samples, tools, tutorials)
  3. Pick resources for your language and use case
  4. Follow implementation guides and official samples

Or ask your AI assistant:

What A2A resources are available for [Python/TypeScript/Java/Go] from the awesome-a2a list?
Intro

Awesome A2A is the go-to curated directory for Google's Agent-to-Agent (A2A) Protocol ecosystem, with 550+ GitHub stars and MIT license. It covers official specifications, SDKs for 5 programming languages (Python, TypeScript, Java, Go, .NET), 40+ official sample implementations, 15+ community SDKs, framework integrations (LangChain, CrewAI, AutoGen), and tutorials. As A2A adoption accelerates alongside MCP, this directory helps developers navigate the rapidly growing ecosystem of agent interoperability tools.

Best for: developers adopting the A2A protocol who need to find SDKs, samples, and integration guides. Covers: official resources, SDKs, frameworks, community projects, tools, tutorials. Updated: community-driven.
