The digital world is on the cusp of its next great transformation: the proliferation of AI agents. These autonomous, goal-oriented systems are rapidly moving from theoretical constructs to practical tools, interacting with our digital infrastructure, our data, and even with each other. As these intelligent entities begin to operate independently, often with access to sensitive systems and information, a critical question arises: How do we establish trust in something that isn't human?
This is where the concept of 'Know Your Agent' (KYA) becomes not just a best practice, but a foundational imperative for AI identity verification. Just as "Know Your Customer" (KYC) protects financial institutions from illicit activity and "Know Your Employee" (KYE) secures internal operations, KYA is emerging as the vital framework for managing the identities, behaviors, and permissions of non-human AI entities.
Built on the MCP‑I (Model Context Protocol – Identity) standard, Vouched’s KYA suite advances AI agent security, uses decentralized identifiers, verifiable credentials, and an Agent Reputation Directory to bring secure, auditable identity to AI-driven workflows.
The proliferation of AI-to-AI and human-to-AI interactions—like Perplexity Pro planning purchases or Gondola AI booking hotel rooms—illustrates how third-party AI agents are already acting on behalf of users in the real world. While these developments boost convenience, they also introduce serious security risks.
Recent studies reveal alarming trends: 42.5% of fraud attempts are now AI-driven, with deepfake attacks occurring every five minutes in 2024. More concerning, 76% of fraud and risk professionals believe AI fraud has targeted their business, highlighting the sophisticated nature of modern threats. These risks include impersonation attacks, unauthorized access to sensitive systems, and fraudulent transactions—all made possible by unauthenticated agents operating without proper identity verification.
These threats showcase the potential for unauthenticated agents to wreak havoc. Without systematic trust frameworks, businesses risk exposure to impersonation, unauthorized access, and automated fraud.
By implementing robust verification systems — including linking agents to verified users — organizations can prevent unauthorized activities, mitigate emerging threats, and ensure modern AI agents operate securely, transparently, and within appropriate governance.
Know Your Agent (KYA) is more than just verifying the identity of autonomous AI agents. It establishes a comprehensive trust framework that ensures alignment between three critical elements: the agent, the human behind the agent, and the agent’s authority to act.
Unlike traditional Know Your Customer (KYC) processes focused solely on human verification, KYA is purpose-built for the complexities of AI-driven systems. These systems operate across platforms, jurisdictions, and use cases, often at machine speed. KYA ensures that AI agents are not acting in isolation or without oversight.
The core principles of KYA, as advanced by Vouched's MCP-I initiative, include:
Authentication: Verifying the identity of the AI agent itself through cryptographic credentials.
User Association Verification: Confirming the verified human user behind the AI agent, ensuring alignment between agent actions and user consent.
Attestation: Verifying the specific permissions and authorities delegated to the agent by the human user or organization.
Reputation Tracking: Continuously monitoring agent behavior and performance to build a dynamic reputation score over time.
Revocation Capabilities: Providing the ability to immediately disable or revoke an agent’s credentials or permissions in the event of compromise or misuse.
These principles mirror established KYC and Know Your Business (KYB) frameworks but are specifically adapted to the distinct risks and behaviors of AI agents — including their ability to self-replicate, evolve behaviors, and interact autonomously with systems.
KYA represents a fundamental evolution in identity management: from human-only verification to holistic, AI-inclusive verification that secures both the digital entity and the person or entity behind it. This shift demands new cryptographic approaches and trust mechanisms specifically designed for AI agents operating in critical environments.
Vouched's comprehensive AI agent security solution addresses trust challenges through three interconnected components that work together to create a robust verification ecosystem.
The MCP-I (Model Context Protocol - Identity) specification extends the popular Model Context Protocol with robust identity capabilities. This groundbreaking framework enables cryptographically verifiable proof that an agent is acting with appropriate authorization from humans.
MCP-I supports three conformance levels:
Level 1 - basic agent identity with DIDs
Level 2 - agent and user identity with verifiable credentials
Level 3 - enterprise-grade with full audit trails and delegation chains
The specification introduces:
Delegated Identity Tokens that cryptographically bind the agent to the verified human user, confirming the chain of authority.
Contextual Boundaries that strictly limit what actions agents are authorized to take, aligned to the user’s intent.
Verifiable Action Trails for complete, auditable records of agent activities tied back to both the agent and the user behind it.
By securing the handshake between the agent, the verified human, and the organization, MCP-I ensures clear accountability and trustworthiness in autonomous AI workflows.
knowthat.ai serves as a transparent directory that allows users to verify agent identities and review reputation data. This community-driven system enables MCP servers to report on agent behavior, creating community-driven assessments of trustworthiness. The platform functions as a "credit scoring system for autonomous software," helping users distinguish between verified and unverified agents.
The registry
tracks agent performance metrics, security protocols, and historical data, providing organizations with critical information needed to make informed decisions about which AI agents to trust with sensitive operations.
The Vouched Agentic Bouncer is an MCP-I server that provides a turnkey SaaS solution for implementing strong identity verification in agent systems.

This standardization enables seamless integration with existing enterprise systems while maintaining the highest security standards.
Implementing KYA creates a multi-layered trust framework critical for secure, compliant automation, especially when AI agents act on behalf of users. It addresses four key areas:
1. Trust Establishment
KYA ensures both the agent and the user behind it are verified before any system access is granted. This eliminates the risk of unauthorized agents impersonating users and keeps your system's integrity intact.
2. Security Enhancement
By using cryptographic identity checks and continuous behavioral monitoring, KYA defends against AI-driven threats. With over 50% of fraud now involving artificial intelligence, organizations need proactive defense mechanisms that can operate at machine speed to counter AI-powered threats.
3. Accountability Mechanisms
KYA provides full audit trails, linking every action to a specific agent–user pair. These logs are essential for traceability, audits, and forensic analysis when AI-driven decisions impact operations or customer outcomes.
4. Compliance Readiness
KYA aligns identity proofing with regulations in high-stakes industries like healthcare and finance. Verifying both agent and user provides a strong foundation for evolving compliance standards — from KYC and KYA to emerging AI regulations.
Imagine an AI agent processing a loan. Under KYA, the agent is cryptographically tied to a verified user and restricted to scope-limited actions. A cloned or unauthorized agent, even if it mimics user behavior, would be blocked immediately based on identity or reputation mismatches.
This ensures that only valid, permissioned automation participates in sensitive workflows, protecting both system integrity and user trust.
The future of AI agent trust depends on widespread adoption of open standards and cross-industry collaboration, similar to how HTTPS became ubiquitous for web security. Vouched envisions an interoperable KYA system with ecosystem-wide MCP-I adoption and reusable agent credentials that work across platforms and organizations.
This evolution will create an "agentic trust layer" that enables scalable, secure digital collaboration between humans, AI agents, and businesses. As the technology matures, we can expect to see standardized certification processes, reputation portability across platforms, and automated trust negotiations between agent systems.
Industry momentum is building rapidly, with organizations recognizing that "thinking through strong identity in advance is critical to building an agentic future that works". The goal is to avoid the mistakes made with early internet protocols, where security was added as an afterthought rather than built from the foundation.
Know Your Agent represents the cornerstone of AI agent safety in our increasingly automated world. As Peter Horadan, CEO of Vouched, notes: "We can't make the same mistake as we build software agents" that was made with email, where inadequate identity verification created lasting security challenges.
KYA frameworks like Vouched's MCP-I-based solution provide the essential infrastructure for trustworthy AI agent deployment. By implementing cryptographic identity verification, reputation tracking, and comprehensive audit capabilities, organizations can harness the power of AI agents while maintaining security and accountability.
The next evolution in digital trust isn't just about technology—it's about creating systems that enable autonomous third-party agents to interact safely and transparently in critical business environments.
