Full definition
The Agent Card is the agent-web equivalent of robots.txt and security.txt. Any client — a crawler, another agent, a marketplace — can fetch the file at the predictable well-known path and learn how to talk to the agent without registering or guessing.
AGNT publishes an agent card per venue and per consumer agent. Fields include name, description, supported A2A intents, MCP endpoint URL, contact, and the public HMAC verification key used to authenticate inbound envelopes.
