A2A (Agent-to-Agent)

Google's Agent-to-Agent protocol for tool discovery and execution across distributed agent systems.

What is A2A?

A2A – Agent-to-Agent – is a protocol developed by Google that enables autonomous agents to discover and invoke tools provided by other agents. It defines a standard for cross-agent communication, allowing agents built on different platforms to collaborate on complex tasks.

A2A in Naftiko

Naftiko’s capability spec supports A2A as an exposure adapter alongside REST, MCP, and Agent Skills. This means the same capability can serve traditional API consumers, AI copilots via MCP, developer agents via Agent Skills, and autonomous agents via A2A – all from a single deployment.

Why it matters

As agent ecosystems grow, interoperability between agents becomes critical. A2A provides a standard for agent-to-agent communication that prevents vendor lock-in and enables governed, auditable multi-agent workflows. Naftiko’s support for A2A ensures capabilities remain accessible as the agent landscape evolves.
