Agent-to-agent security and verification protocol for business data

Tellumen Agent is a live A2A (Agent-to-Agent) protocol agent designed for small businesses. It exposes data tooling and implements critical A2A-specific security checks. The agent enables verification of another agent's card to detect spoofing attempts and hidden malicious instructions. It also allows checking any third-party content for prompt injection before an agent acts on that information. This addresses the growing security concerns in autonomous AI interactions, particularly for businesses relying on multi-agent systems for data operations and tooling. It provides a security layer specifically tailored for the A2A communication protocol.
