What it does

Wardn provides a secure vault and proxy layer that isolates sensitive credentials from AI agents. Instead of providing real API keys in environment variables—which are prone to leakage via logs or prompt injections—Wardn gives agents useless placeholder tokens. The real keys are securely stored in an encrypted vault and injected only at the network layer by the Wardn daemon.

Tools

get_credential_ref: Returns a placeholder token for a specific credential.
list_credentials: Lists all credentials the agent is authorized to access.
check_rate_limit: Provides remaining quota and retry information for a credential.

Installation
