Agent Transfer Protocol: Server-Mediated Agent-to-Agent Communication Architecture for the Agentic Web

The paper introduces the Agent Transfer Protocol (ATP), a cross‑organization communication protocol designed to enable continuous collaboration among agents from different administrative domains. ATP uses domain‑mediated servers to maintain stable addresses, store messages for offline instances, and verify message integrity, allowing agents to operate independently of continuous connectivity. A prototype implementation demonstrated that business workflows could continue after instances went offline, with successful verification of message source and content and quantified latency overhead.

Agent Status Protocol (ASP): A Lightweight Specification for State Reporting in Multi-Agent Systems

The Agent Status Protocol (ASP) is a lightweight specification that enables heterogeneous AI agents to report their operational state to a status server via small JSON events over HTTP POST. The server aggregates these reports and exposes the combined state to observers through Server‑Sent Events (SSE), inferring liveness from missed heartbeats and incorporating observations from supervisors, guardrails, operators, and peers. ASP models state across independent dimensions—lifecycle, health, task, floor, governance—allowing an agent to simultaneously be online, degraded, working on a task, and waiting for the floor, while reusing existing vocabularies from A2A, OFP, and OpenTelemetry GenAI conventions.

Deterministic Replay for AI Agent Systems

arXiv:2607. 16200v1 Announce Type: new Abstract: AI agent systems that couple large language models (LLMs) with external tools and APIs are inherently non-deterministic: LLM sampling variance, external API state, CDN infrastructure headers, and execution-environment noise collectively prevent any prior agent run from being faithfully re-executed.

Attested Tool-Server Admission: A Security Extension to the Model Context Protocol

arXiv:2605. 24248v2 Announce Type: replace-cross Abstract: The Model Context Protocol (MCP) standardizes how a large-language-model (LLM) agent and an external tool server exchange messages, but not trust: a host reads a server's self-declared tool list and dispatches calls, with no notion of which servers it may use, at what sensitivity, or which of a server's tools are in bounds.
