Vault FAQs

Question 1

How does Vault prevent credential leakage in Large Language Models (LLMs)?

Accepted Answer

Vault employs secure credential isolation by storing sensitive data encrypted with AES-256-GCM. When an AI agent requires credentials for a login or API call, Vault handles the operation directly (e.g., via automated browser login or API proxy) and only returns a status confirmation to the LLM, ensuring the actual credentials never enter the LLM's context.

Question 2

What is Vault and how does it secure AI agents?

Accepted Answer

Vault is a Model Context Protocol (MCP) server designed to isolate sensitive credentials, such as passwords and API keys, from an LLM's context window. This prevents AI agents from ever seeing or storing critical login information, significantly enhancing security by eliminating the risk of accidental leakage.

Question 3

What security features does Vault offer for credential management?

Accepted Answer

Vault provides robust security features including AES-256-GCM encrypted storage with unique Initialization Vectors, a tamper-proof audit trail logged with a SHA-256 hash chain for all credential activities, automated secure browser login using Chrome DevTools Protocol, and an API Key Proxy that injects keys into requests while sanitizing responses to prevent accidental leakage.

Question 4

How does Vault ensure accountability and detect unauthorized access or modifications?

Accepted Answer

Vault maintains a comprehensive and tamper-proof audit trail. Every credential event—creation, usage, and removal—is logged with a SHA-256 hash chain. This ensures that the audit log cannot be modified without detection, providing full accountability and the ability to track all credential activities for security compliance.

Question 5

Can Vault manage both web login credentials and API keys for AI agents?

Accepted Answer

Yes, Vault is designed to manage both. It securely fills web forms for user logins via its automated browser login feature, and for API keys, it acts as a proxy, injecting the keys into requests and then scanning responses to ensure the key is not inadvertently returned to the LLM, covering both common credential types.
