Outline

This paper highlights the need for a standardized registry system for autonomous AI agents scaling in cloud, enterprise, and distributed environments. It examines three leading registry approaches: MCP's mcp.json, A2A's Agent Card, and NANDA's AgentFacts. Each approach utilizes a unique metadata model, featuring a centralized metaregistry (MCP), decentralized interaction (A2A), and a cryptographically verifiable and privacy-preserving metadata model (NANDA). The paper compares and analyzes the three approaches across four dimensions: security, scalability, authentication, and maintainability, and offers suggestions and recommendations for the future design and adoption of registry systems for the Internet of AI agents.

Takeaways, Limitations

Takeaways:
It highlights the importance of a standardized registry system to improve the interoperability and discoverability of autonomous AI agents.
We compare and analyze the pros and cons of various registry approaches (centralized, decentralized, and cryptographically based) to provide insights into future system design.
We present specific recommendations for the design and adoption of a registry system to advance the Internet of AI agents.
Limitations:
There may be a lack of consideration of approaches other than the three registry approaches.
Further analysis may be required to determine the practical implementation and applicability of the presented recommendations.
Specific benchmarking results comparing the performance of each approach may not be provided.
