Fullmakt

What is Fullmakt?

Fullmakt is a credential broker for AI agents. Your agent gets a short-lived, scoped token; your real API keys stay in the vault and get injected server-side, only after policy allows the call. Unlike token vaults that hand the credential back to the agent and exit, Fullmakt stays in-path — so every call lands in a tamper-proof, cryptographically chained audit log.
