Announcing the Agent2Agent Protocol (A2A)

Google Cloud Announces Agent2Agent (A2A) Protocol for AI Agent Interoperability

**Key Points:**

* **Purpose:** The A2A protocol aims to enable AI agents to communicate, exchange information, and coordinate actions across various enterprise platforms and applications, regardless of their underlying technologies or vendors. This allows for greater autonomy and efficiency in automating complex workflows.

* **Open Standard:** A2A is an open-source protocol designed to complement Anthropic's Model Context Protocol (MCP).

* **Key Features:**

* **Capability Discovery:** Agents can advertise their capabilities using "Agent Cards."

* **Task Management:** Facilitates communication and status updates for task completion.

* **Collaboration:** Allows agents to exchange context, replies, artifacts, and user instructions.

* **User Experience Negotiation:** Agents can negotiate the format of content (text, images, video, etc.) and UI capabilities.

* **Security:** Designed with enterprise-grade authentication and authorization.

* **Supports Long-Running Tasks:** Handles tasks that may take hours or days, with real-time feedback.

* **Modality Agnostic:** Supports text, audio, and video.

* **How it works:** The protocol facilitates communication between a "client" agent (initiates tasks) and a "remote" agent (executes tasks).

* **Real-World Example:** The article uses the example of candidate sourcing for hiring software engineers, demonstrating how multiple specialized agents can collaborate to streamline the process.

* **Partner Support:** Over 50 technology partners and service providers (including Atlassian, Box, Salesforce, Accenture, Deloitte, and more) are contributing to and supporting the A2A protocol. Their quotes emphasize the importance of interoperability for unlocking the full potential of AI agents.

* **Design Principles:** The protocol is designed with the following key principles:

* Embrace agentic capabilities

* Build on existing standards

* Secure by default

* Support for long-running tasks

* Modality agnostic
