Features

Built for how you ship.

A quiet layer between your apps and the APIs they call. Encrypted, observable, and invisible by default.

Encrypted vault

Your keys, locked behind device-bound auth.

Every credential is encrypted at rest with a master token bound to your machine. Rotate on a schedule, issue scoped tokens per project, and revoke instantly — without touching the underlying key.

Smart proxy

Stream responses without exposing the key.

Your app hits the proxy. The proxy injects the real credential, forwards to the provider, and streams the response back — SSE and all. Your raw key never leaves the vault.

MCP ready

Built for AI agents from day one.

Expose your vault to Claude, Cursor, or any MCP-compatible client. Agents call real APIs without ever seeing the underlying credentials — and every call is logged, scoped, and revocable.
