Cred

什麼是 Cred？

AI agents need OAuth tokens for user accounts, but most frameworks store them in plaintext config files. Cred is open-source credential delegation middleware. The user consents once. Cred encrypts the refresh token (AES-256-GCM) and never returns it. Agents get short-lived tokens on demand. Every delegation produces a cryptographic audit receipt. We also ship CredX: a single-command encrypted credential store for agents who don't need the full SDK. Self-hosted. Apache 2.0. Zero cloud dependency.
