Self Labs launched Agent Vault, a hosted browser proxy enabling agents like Claude Code and Codex to checkout and sign in using placeholder tokens. The proxy injects real card numbers or passwords only at the moment of filling, ensuring agents never hold stealable credentials. This architecture limits potential damage from prompt injection attacks to user-defined spending caps, significantly enhancing security for autonomous agents in financial transactions.

    • Agent Vault uses a 'placeholder token + real-time proxy fill' mechanism, preventing agents from directly accessing real bank cards or passwords.
    • The solution effectively defends against prompt injection attacks by limiting potential losses to user-defined spending caps.
    • Supports mainstream coding and general-purpose agents (e.g., Claude Code, Codex, Grok Bot), aiming to be a key component of the agentic identity and privacy stack.
