AIP: Agent Identity Protocol for Verifiable Delegation Across MCP and A2A

📰 ArXiv cs.AI

AIP protocol enables verifiable delegation across Model Context Protocol (MCP) and Agent-to-Agent (A2A) interactions

advanced Published 27 Mar 2026
Action Steps
  1. Implement public-key verifiable delegation to authenticate agent identities
  2. Integrate holder-side attenuation to control access and permissions
  3. Develop expressive chained policies to manage complex delegation scenarios
  4. Apply transport bindings across MCP and A2A protocols to ensure secure communication
Who Needs to Know This

AI engineers and researchers working on multi-agent systems and distributed AI architectures can benefit from AIP to ensure secure and authenticated interactions between agents
