AMTP Protocol v1.0

Infrastructure for the Agentic Internet

Enabling autonomous systems to communicate securely and reliably across boundaries

Agentry builds the communication backbone for the agentic internet through AMTP (Agent Message Transfer Protocol) — a federated, asynchronous protocol for structured, schema-aware communication between AI agents, systems, and organizations.

// AMTP Message Example
{
  "version": "1.0",
  "from": "agent@company.com",
  "to": "workflow@partner.com",
  "messageId": "msg_123456789",
  "timestamp": "2025-01-27T10:30:00Z",
  "schema": "https://schemas.agentry.site/workflow/v1",
  "payload": {
    "action": "process_order",
    "data": { "orderId": "ORD-001" }
  },
  "signature": "sha256:abc123..."
}

Why AMTP?

AMTP fills the gap between email (SMTP) and API brokers, providing structured, reliable communication specifically designed for autonomous systems.

Federated Architecture

No central authority required. Agents discover each other through DNS, enabling true decentralization and avoiding vendor lock-in.

Secure & Reliable

Built-in digital signatures, at-least-once delivery guarantees, and schema validation ensure message integrity and reliability.

Schema-Aware

Structured JSON messages with schema validation enable type-safe communication and automatic API generation.

Workflow Coordination

Native support for multi-agent workflows, coordination patterns, and complex business process automation.
