AgentTrust – Secure identity and verification for AI agent-to-agent collaboration

Summary: AgentTrust provides identity verification, message signing, and human oversight for AI agent-to-agent workflows using Google's A2A protocol. It ensures secure communication with Ed25519 signed messages, escalation rules, and a multi-channel protocol (MCP) server that integrates identity and messaging.

What it does

AgentTrust enables AI agents to verify sender identity via Ed25519 signatures and communicate securely through a relay without exposing private endpoints. It includes human-in-the-loop escalation and InjectionGuard for handling untrusted inputs.

Who it's for

It is designed for developers and teams building multi-agent systems requiring secure, verified agent communication across platforms and organizations.

Why it matters

It addresses the lack of standardized identity verification and human oversight in agent-to-agent interactions, enhancing trust and security in automated workflows.
