The A2A Directory project provides an open protocol and resources for secure, collaborative AI agent communication, enabling cross-application automation. It targets developers building AI agent systems, offering a standardized way for agents to interact, share data, and execute tasks across different platforms.

How It Works

A2A leverages standard web technologies like HTTP, JSON-RPC, and Server-Sent Events (SSE) for communication. Its design prioritizes security, privacy, and asynchronous operations, making it suitable for enterprise environments. The protocol is modality-agnostic, supporting text, files, forms, and streams, and allows for opaque execution, meaning agents can interact without exposing their internal logic.

Quick Start & Requirements

• Install/Run: Clone the official repository (github.com/google/A2A) and follow instructions in the /samples directory. Official libraries are available for Python and JavaScript/TypeScript.
• Prerequisites: Standard development environment; specific samples may have additional dependencies.
• Resources:
  • Website: google.github.io/A2A
  • Technical Documentation: google.github.io/A2A/docs/
  • Demo Video: Linked within the README.

Highlighted Details

• Supports secure, private, and asynchronous agent-to-agent communication.
• Modality-agnostic: handles text, files, forms, and streams.
• Opaque execution allows agents to interact without revealing internal logic.
• Integrates with popular AI frameworks like LangGraph, CrewAI, and Genkit.

Maintenance & Community

The project is officially from Google. Community implementations and contributions are encouraged via GitHub Issues and Discussions.

Licensing & Compatibility

The README does not explicitly state a license. Compatibility for commercial use or closed-source linking is not specified.

Limitations & Caveats

The project is presented as a protocol and set of samples; a comprehensive, production-ready SDK is not explicitly detailed. License information is missing, which may impact commercial adoption.
