Agent Vault: Secure Credentials for Your AI Systems
We’re excited to introduce Agent Vault, an open-source HTTP credential proxy and vault designed specifically for AI agents. Addressing a critical challenge in the industry – how to provide secure access without exposing secrets – Agent Vault acts as a trusted intermediary between your agents and the services they need.
The Problem of Credential Exfiltration
As teams build increasingly sophisticated agentic systems, they inevitably encounter the need for credentials. However, agents’ non-deterministic nature and susceptibility to prompt injection create significant security risks. Direct access to secrets can lead to credential exfiltration, where malicious actors exploit vulnerabilities to steal sensitive information.
Our Solution: Credential Brokering with Agent Vault
Agent Vault implements a credential brokering pattern similar to those used by leading AI platforms like Anthropic and Cloudflare. Instead of giving agents direct access, we create a secure proxy that:
- Terminates TLS connections for inspection and rule enforcement
- Attaches credentials to requests before forwarding them
- Prevents agents from ever “seeing” the actual secrets
This approach ensures that even if an agent is compromised, attackers cannot steal the credentials themselves.
Key Features of Agent Vault
- Portable: Single Go binary with Docker support for flexible deployment
- Interface-agnostic: Works seamlessly with APIs, CLIs, SDKs, and more
- MITM architecture: Enables traffic inspection and advanced security policies
- Extensible: Can be expanded to include firewall-like features at the proxy layer
Getting Started
You can deploy Agent Vault as a dedicated service and configure your agents to route all outbound traffic through it. While the initial setup requires some manual configuration, we believe this provides the most universal solution across different agent frameworks.
We’re committed to making Agent Vault more user-friendly through community contributions – please share your feedback and help us improve the developer experience!
