The leader in AI Identity Verification launches KnowThat.ai, an Agent Reputation Directory, as part of its “Know Your Agent” suite— which includes proposed Identity enhancements to the MCP protocol.

Vouched, the leader in AI-powered identity verification, today announced the launch of several initiatives to ensure the coming ecosystem of AI Software Agents is built on a foundation of strong identity and trust. These include Agent Reputation Directory, a groundbreaking solution designed to address the critical gap in identity and trust for autonomous software agents – or, how to tell good agents from bad. As AI agents become increasingly integral to digital workflows, this tool ensures that only verified, trustworthy agents can participate in sensitive operations-protecting organizations and individuals from fraud, impersonation, and unauthorized access.

As AI agents have become more autonomous and are entrusted with sensitive tasks, the need for reliable identity and reputation standards is more urgent than ever. Existing protocols, like the Model Context Protocol (MCP), have led to a breakthrough in allowing AI systems to talk to each other. As exciting and innovative as these protocols are, they need to be extended with comprehensive identity features to avoid leaving users exposed to risks of impersonation and fraud.

As AI agents increasingly represent individuals and organizations in digital interactions, Vouched’s Know Your Agent introduces a suite of innovations that close critical identity gaps:

• MCP-I (MCP-Identity): A proposed extension to the MCP protocol, MCP-I adds robust identity capabilities for both agents and humans, enabling secure, identity-aware communication in agent-based ecosystems.
• Vouched MCP-Identity Server: A turnkey SaaS solution with easy-to-integrate APIs for strong identity verification in agent systems and applications. It includes a developer toolkit for AI agents to securely store verified credentials and delegations. Aligned with the MCP-I specification, the SDK supports scalable, standards-based identity integration for AI-driven workflows.
• Know That AI (http://knowthat.ai): A transparent Agent Reputation Directory that allows users to verify agent identities and review reputation data, with a core focus on fraud prevention and digital trust. Know That AI is a community-driven system where MCP Servers can report on the behavior of software agents (good or bad) to lead to a community-driven assessment of that agent’s trustworthiness.

“Thinking through strong identity in advance is critical to building an agentic future that works,” said Peter Horadan, CEO of Vouched. “In some ways we’ve seen this movie before. For example, when our industry designed email, they never anticipated that there would be bad email senders. As a result, we’re still dealing with spam problems 50 years later. We can’t make the same mistake as we build software agents. The work we have released today solves these problems.”

The Agent Reputation Directory at KnowThat.ai the MCP-I specification is open and free to the public. The Vouched MCP-Identity Server is available as a commercial SaaS solution for those seeking a turnkey implementation.

Know Your Agent and the Agent Reputation Directory are available starting May 22, 2025. Technical documentation and a launch video are available on the Vouched website.
