# runner_auth_credentials_import

Copy a runner subscription token (Claude Max / Pro, or ChatGPT Plus / Pro for codex) from an already-signed-in machine to a remote one. Yaver is a single-user wrapper, so this is the preferred path when the user already has working subscription auth locally — it avoids re-running OAuth on every box (which hits the SSH-launched-daemon Keychain wall on macOS). Subscription only; never use API keys.

## Why runner_auth_credentials_import is rated Medium

This tool transfers authentication credentials (subscription tokens) to a remote machine. It writes/imports credential data to another system. While it is reversible in principle (credentials can be revoked), the act of copying auth tokens to remote machines carries high severity due to the risk of credential exposure or unauthorized access if misused by an AI agent — e.g., exfiltrating tokens to an…

From the tool's own definition: "Copy a runner subscription token... from an already-signed-in machine to a remote one"

## Use case

AI agents use runner_auth_credentials_import to create or update resources in Yaver, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Yaver environment.
