ACPs: Agent Collaboration Protocols for the Internet of Agents
This work addresses interoperability, scalability, and coordination challenges for developers and users in the IoA domain, but it appears incremental as it builds on existing protocols like MCP, A2A, and ANP.
The paper tackles the problem of fragmented and scenario-specific communication protocols for autonomous agents in the Internet of Agents (IoA) by proposing Agent Collaboration Protocols (ACPs), a comprehensive suite that includes registration, discovery, interaction, and tooling protocols, and demonstrates its effectiveness in a collaborative restaurant booking scenario.
With the rapid advancement of artificial intelligence, the proliferation of autonomous agents has introduced new challenges in interoperability, scalability, and coordination. The Internet of Agents (IoA) aims to interconnect heterogeneous agents through standardized communication protocols, enabling seamless collaboration and intelligent task execution. However, existing agent communication protocols such as MCP, A2A, and ANP remain fragmented and scenario-specific. To address this gap, we propose Agent Collaboration Protocols (ACPs), a comprehensive protocol suite for the IoA. ACPs include registration, discovery, interaction, and tooling protocols to support trustable access, capability orchestration, and workflow construction. We present the architecture, key technologies, and application workflows of ACPs, and demonstrate its effectiveness in a collaborative restaurant booking scenario. ACPs lay the foundation for building a secure, open, and scalable agent internet infrastructure.
