Smilyvi Shvorni — Project Overview and Architecture
Inspiration
We were inspired by the growing complexity of AI agent interactions and the critical need for secure credential management. Many AI agents store sensitive tokens in plaintext or insecure environments, posing a huge security risk. We wanted to build a solution where an autonomous agent can handle complex tasks while keeping user secrets safe using a professional-grade vault.
What it does
Our project, Smilyvi Shvorni, is a Secure Autonomous AI Agent. It integrates Auth0 Token Vault with LlamaIndex to create a workflow where the agent can access third-party APIs (like calendars or databases) without ever exposing the raw credentials to the LLM or the client-side code. It’s a "brain" that is both smart and security-conscious.
How we built it
Authentication & Security: We used Auth0 for user identity and Auth0 Token Vault for secure storage of API tokens.
AI Logic: The core agent is built on LlamaIndex, which handles the orchestration of tools and data.
Inference: We used Groq to get lightning-fast responses from the LLM.
Backend: Developed with Python, ensuring seamless integration between security layers and AI components.
Challenges we ran into
The biggest hurdle was synchronizing the asynchronous nature of AI agent calls with the secure handshake of the Auth0 Token Vault. Ensuring that the agent correctly identifies when it needs a token and retrieves it securely without breaking the conversation flow required several iterations of our tool-calling logic.
Accomplishments that we're proud of
We are incredibly proud of successfully bridging the gap between "autonomous action" and "enterprise security." Building a functional agent that actually respects the boundaries of a secure vault is a big win for our team, Smilyvi Shvorni.
What we learned
We learned a lot about the inner workings of Token Vaults and how to properly "sanitize" an agent's environment. We also deepened our knowledge of LlamaIndex’s agentic framework and how to optimize LLM performance using Groq.
What's next for Auth0 AI
We plan to expand this into a multi-agent system where different agents have different "security clearances." We also want to implement more complex "human-in-the-loop" confirmations for sensitive actions requested by the agent.
Bonus Blog Post: Securing AI with Auth0 Token Vault
Our journey during this hackathon led us to a critical realization: AI agents are only as good as the trust we place in them. Integrating Auth0 Token Vault was a game-changer for Smilyvi Shvorni.
The main technical hurdle was decoupling the LLM's logic from the actual API credentials. Usually, developers pass tokens directly into the prompt context or environment variables that the agent can read. By using the Token Vault, we ensured that our LlamaIndex agent only handles "references" to secrets. When the agent needs to fetch data, the secure handshake happens behind the scenes.
This approach mitigates the risk of prompt injection attacks where a malicious user might try to trick the agent into revealing its API keys. We've learned that security shouldn't be an afterthought in AI development—it should be the foundation.
