Open-source identity & trust layer for AI agents
HelixID is an innovative open-source identity layer designed for AI agents, elevating trust and verification beyond traditional session-based access. Unlike typical agent-auth tools that rely solely on one-time tokens, HelixID assigns each AI agent a W3C Verifiable Credential and Decentralized Identifier (DID), enabling cross-organizational, offline, and post-action verification. This approach ensures that an agent’s identity, authority, and actions can be transparently proven, fostering greater security and accountability in AI deployments. Its compatibility with existing OAuth systems and enforcement via OPA/Rego makes it highly adaptable, while its self-hostable nature allows quick setup within minutes, all under the permissive Apache 2.0 license, ensuring no vendor lock-in. HelixID is perfect for developers seeking a robust, open-source solution to embed trust and provenance into AI workflows, especially in sensitive or regulated environments.
