Ship agents fast. Without the identity drag.

Yes. Scaling AI isn’t just about compute; it’s about managing a massive web of human-to-agent and agent-to-agent interactions. Auth0 for AI Agents provides a centralized identity plane that manages these connections at scale, helping ensure that as your workflows become more complex, your security posture remains consistent and automated.

Building a secure production-ready environment requires manual RBAC implementation, penetration testing, regulatory compliance reviews, and data governance, a process that costs upwards of $200k in engineering time. Offloading to Auth0 helps ensure that sensitive third-party keys never touch your code or logs, while automated rotation and MFA protect you from credential leakage, allowing you to ship with confidence.

With our upcoming Agent as Principal and Agentic Commerce launches, Auth0 for AI Agents will provide dedicated Machine-to-Machine (M2M) identities for your agents at scale. This helps ensure every agent has a strictly scoped identity, making it easy to track which agent or human did what, even in fully autonomous loops. You get a clear audit trail and can revoke an individual agent’s access without taking down your entire workflow.

The biggest risk is an agent retrieving data that the user shouldn't see. Auth0 for AI Agents integrates Fine-Grained Authorization (FGA) directly into your RAG pipeline. By checking permissions at the moment of retrieval, we help ensure your LLM only sees and processes documents that the specific authenticated user is authorized to access. This prevents prompt-injection-based data leaks and helps ensure your proprietary data stays siloed.

The FGA Permissions Index handles the immense scale of enterprise RAG workflows by shifting the high computational cost of authorization from query time to write time. Instead of forcing the AI to wait on real-time graph traversal API calls for every single document snippet it searches, the system pre-calculates all possible permissions into direct 1:1 relationships whenever a permission changes.

Auth0 for AI Agents’ Token Vault solution acts like a secure proxy. Your agent never actually holds the root key; instead, it asks Token Vault for a temporary, short-lived access token only when it needs to perform a specific task. By keeping access tokens short-lived, Token Vault drastically reduces the attack surface a stolen credential exposes.

The Auth for MCP offering relieves developers of the need to implement the authorization parts of the MCP spec from scratch. OAuth 2.1 and OIDC are inherently built into the Auth0 platform, providing frictionless sign-in capabilities, standards-based discovery and client registration, resource-scoped tokens, permission downscoping through token exchange, and fine-grained authorization. When an MCP server is protected by Auth0, MCP clients and agents alike need a properly scoped access token to call the server.

Auth0 for AI Agents helps secure your LangChain app through user authentication (log in before interacting), a Token Vault (helps securely manage tokens for tools like Google or Slack), fine-grained RAG authorization (agents only retrieve documents the user can access), and human-in-the-loop approvals (pause for user consent before critical tool calls).
