Protocol
A2A (Agent-to-Agent protocol)
An open protocol for secure communication and coordination between AI agents.
A2A is the Agent-to-Agent protocol for interoperability between agents across systems, vendors, and platforms. In governed commerce, it matters because agents may need to discover one another, exchange task state, delegate work, and hand control across business systems without losing identity, permission, or audit context.
Why it matters
Commerce teams will not run one isolated agent forever. They will run networks of assistants, workflow agents, support agents, and operations agents. A2A makes coordination possible, but also raises the governance bar.
How HARNEXA uses it
HARNEXA treats A2A as a readiness layer only until identity, scope, approval, and AgentOps evidence are in place.
FAQ
Questions this definition answers.
Does HARNEXA expose public A2A execution?
No. Public HARNEXA surfaces explain A2A readiness and boundaries. Execution remains private, scoped, and reviewable.
Why does A2A matter for commerce?
It lets agents coordinate across discovery, product data, fulfilment, support, and operations workflows without forcing every capability into one agent.
