Prefactor

Prefactor is an authentication platform designed for AI agents that provides secure authorization and auditing capabilities through its Model-Context-Protocol layer. The system implements human-delegated authentication and access control with code-defined auditable infrastructure that integrates with existing OAuth/OIDC-based systems, allowing AI agents to securely access APIs and applications. Prefactor supports roles, attributes, and delegated access in a unified model, making it appropriate for SaaS applications with complex agent-based access patterns. The platform offers agent-level audit trails by default and enables organizations to define access logic once then scale as needed. Prefactor maintains control at machine scale through policy-as-code and delegated trust access, giving each customer secure isolated agent identities with scoped permissions.
