You'd reach for this when you need Claude to interact with systems that require secrets, but don't want those credentials exposed in prompts or context. It's a vault that stores encrypted environment variables and lets you set granular access policies controlling which secrets an AI agent can actually touch. Think API keys, database passwords, or tokens that your workflow needs but shouldn't be visible to the model itself. The policy layer means you can allow access to some vars while keeping others locked down, so Claude can invoke authenticated operations without ever seeing the raw credentials. Useful for building agents that need to operate in production environments without compromising your security posture.
