What is A2A?
Google's protocol for AI agents from different vendors to communicate with each other in a standardized way.
// Explanation
A2A (Agent-to-Agent) is an open protocol driven by Google that lets AI agents from different companies discover, communicate, and collaborate regardless of who built them. If MCP is the 'USB' connecting an agent to tools, A2A is the 'common language' that lets two agents talk to each other. Together, MCP and A2A form the infrastructure for an interoperable multi-agent ecosystem.
// Example
An agent at your company (built with Claude) needs data from your vendor's agent (built with Gemini). With A2A, they communicate directly without anyone writing a custom integration.
