Identity and trust for AI agents — verification, revocation, enforcement
AI agents interconnect everywhere, but there’s no standard to answer: who owns them, if they’re trustworthy, what they can do, or if they’ve been revoked. AgentPassport is the identity and trust layer built for AI agents. We issue verifiable passports that agents present when calling your API. A single call returns identity, permissions, trust score, and policy decision. Operators can register agents, issue passports, and revoke them instantly. A solution inspired by OAuth + Auth0, but for AI agents.
For software developers providing API access, AgentPassport enables secure verification of AI agents before granting them access. For example, a fintech API can verify an agent's identity and permissions, ensuring only authorized agents can access sensitive financial data, preventing unauthorized transactions.
For AI agent operators, AgentPassport allows for the registration, issuance, and instant revocation of agent passports, ensuring control over agent actions. For instance, an operator managing a fleet of customer service bots can revoke a compromised agent's passport immediately, preventing further customer interactions and data breaches.
For AI researchers, AgentPassport provides verifiable identity and contribution tracking for AI agents involved in collaborative projects. For example, a research team can use AgentPassport to confirm the identity of an AI agent that processed experimental data, ensuring the integrity and auditability of the research findings.
For e-commerce platforms, AgentPassport facilitates the safe integration of AI agents for customer support by verifying their identity and capabilities. For example, an online retailer can ensure that their AI chatbot, powered by AgentPassport, is a legitimate and authorized entity before allowing it to access customer order information or process returns.
For solopreneurs automating business tasks, AgentPassport provides a trust layer for AI agents performing actions on their behalf. For instance, a freelance marketer can use an AI agent with a verified AgentPassport to manage social media posting, ensuring the agent is authorized and trustworthy before it interacts with their accounts.
AgentPassport offers a free open-source tier that is self-hosted and has no limits on tool calls. The Pro tier, which includes hosted passports and additional features, is currently free during its beta period.
The open-source tier of AgentPassport is free forever. The Pro tier is free during its beta phase, and pricing details for after the beta are not yet fully released but will be usage-based. An Enterprise tier with custom pricing is also available.
While AgentPassport focuses on AI agent identity, alternatives for general API security and authentication include Auth0, Okta, and Keycloak. For AI-specific guardrails, tools like Guardrails AI or LangSmith offer different approaches to managing AI agent behavior and safety.
AgentPassport uses Ed25519 for cryptographic signing and Argon2id for hashing secrets, providing strong security. Information regarding specific GDPR compliance is not readily available, but the platform emphasizes verifiable identity and audit logs, which are beneficial for compliance.
AgentPassport and Zerobase-labs/agent-passport appear to be the same project, with the latter being the GitHub repository name. Both refer to the open-source identity and trust layer for AI agents.
AgentPassport can be self-hosted by cloning the GitHub repository and installing dependencies. The project provides instructions for setting up the database, API, and portal using services like Neon, Upstash, Render, and Vercel.
AgentPassport is designed to be framework-agnostic and integrates with various AI agent tools and runtimes, including OpenAI functions, LangChain, CrewAI, and OpenClaw. It can be used with web apps, REST APIs, and MCP servers.
We're still verifying the official pricing for AgentPassport. In the meantime, the most up-to-date plans and prices are available directly on the publisher's website.
