ACP (Agent Communication Protocol) runtime for building secure, interoperable AI agents

ACP — Agent Communication Protocol

ACP (Agent Communication Protocol) is a secure, identity-driven protocol for autonomous systems to communicate, collaborate, and coordinate across environments.

Unlike traditional API integrations or message brokers, ACP is designed for AI agents operating in dynamic, distributed ecosystems.

What is ACP?

ACP provides:

• Identity-first communication between agents
• Signed and optionally encrypted message envelopes
• Transport independence (HTTP, AMQP, MQTT)
• Relay-based routing across network boundaries
• Capability-driven interaction patterns

This enables agents to discover each other, exchange messages, and collaborate without tight coupling.

Why ACP?

Modern systems are evolving from services into autonomous agents.

Current approaches (REST APIs, webhooks, point-to-point messaging) lead to:

• brittle integrations
• hidden coupling
• limited interoperability
• lack of governance

ACP introduces a protocol layer for agent communication, similar to how HTTP enabled the web.
