What is A2A (Agent2Agent protocol)?

A2A is an open protocol, started by Google and now run under the Linux Foundation, that lets AI agents discover and call each other across companies and platforms. Each agent publishes an Agent Card describing its skills and endpoint, and other agents send it messages over JSON-RPC. sebbi.pro is an A2A agent, so Gemini Enterprise, Google's agent tools and any A2A client can use it.

How it works

  1. An agent publishes its card at /.well-known/agent-card.json.
  2. Other agents read the card and call the endpoint with message/send.
  3. sebbi.pro's card lists its skills: notarise, verify proofs, compliance checks, seal decisions, spending sign-off.
  4. MCP connects an AI to tools. A2A connects agents to agents. sebbi.pro speaks both.
