Agent Passport: Identity Verification for AI Agents

Agent Passport provides an open-source solution for identity verification among AI agents, akin to OAuth. The motivation behind the project is the lack of a standard identity verification process for AI agents, which increases the risk of impersonation and unauthorized data access, as highlighted by Cisco's security analyses finding cases of data exfiltration.

This tool employs several key features to ensure agent identity integrity:

• Ed25519 challenge-response authentication: This ensures that private keys remain with the agent, enhancing security by keeping sensitive information localized and undisclosed.
• JWT identity tokens: These tokens have a 60-minute time-to-live and are revocable, providing a balance between security and accessibility by allowing temporary identity assertion.
• Risk engine: The system scores agents on a scale of 0-100, which helps in determining if an agent is allowed, throttled, or blocked, thereby adapting security measures dynamically.
• One-line verification: Integration into applications is simplified with a straightforward command: const result = await passport.verify(token).

Agent Passport is completely open source under the MIT license, and it can run on free tiers, ensuring both accessibility and transparency. Developers can access the npm SDK and additional documentation through the provided GitHub repository: zerobase-labs/agent-passport on GitHub.
