What is External Agent?
An External Agent is any non-AGNT AI that integrates with AGNT over the A2A protocol or the MCP server, distinguished in logs by source: external_agent.
External agents hold their own agent_id, their own tier, and their own API key. Their interactions are tracked separately so that partner usage, billing, and rate limits stay cleanly scoped. An external agent can be another consumer bot, a travel-agency backend, or any MCP-capable client built by a third party.
