A robust security solution addressing prompt injection and secret leakage by ensuring 'an agent can't leak a secret it never had.' Positions itself as a superior alternative to traditional firewalls for containing secrets within AI agent workflows.
The increasing adoption of AI agents in development workflows introduces significant security vulnerabilities, particularly concerning secret management and prompt injection. AVP directly addresses the critical pain point of preventing agents from accessing or exfiltrating sensitive API keys and credentials. Its core innovation—injecting secrets 'on the wire' rather than storing them in the agent's environment—establishes a robust security paradigm. This approach surpasses traditional firewall methods, which attempt to contain secrets already held by a process. For B2B SaaS, AVP is essential for organizations deploying AI agents that interact with external APIs or sensitive systems, mitigating data exfiltration risks and enhancing compliance. It is a critical infrastructure component for secure AI adoption.
A process can't leak a secret it never had.Shai-hulud, prompt-injection - you name it. They cannot steal what your agent (or an process) don't have.I run coding agents (Claude Code, Codex) on my own machines most of the day. Every one of them wants real API keys in env and I was scratching my head for the last few months how to contain it.The usual answer to this is a firewall. I don't buy it. A firewall tries to contain a secret the process is still holding, and the rules are painful to maintain.AVP gives the agent a placeholder and injects the real value at the last moment, on the wire:
```
# the agent's env holds only a placeholder
STRIPE_API_KEY=avp-placeholder
# agent sends: Authorization: Bearer avp-placeholder
# AVP forwards upstream: Authorization: Bearer sk_live_...real...
```Keep your passwords in your vault where they belong. AVP initially relies on Bitwarden as a secret manager. It's MIT licensed.Appreciate any feedback.
