I built this as i thought this model could better to what other tools are doing. What do you guys think ?Harbinger is an mTLS proxy that sits in front of an AI agent s outbound traffic. Every AI agent, bot, and service account gets a cryptographic identity. Every request it makes is checked against policy before it s allowed, and any real secret it needs is pulled from your own vault and swapped in only when the request is verified to be going where it claims. The agent itself never holds a standing credential.
