--json gives machine-readable output on success and on failure.
Signing in and connecting
init connects agents through the app rather than the cloud. The app opens if it is closed. --cloud, --base-url, --workspace, ES_API_KEY or ES_BASE_URL keep a command on the cloud, which requires eversince login.
Working
Options
Environment variables:
ES_API_KEY, ES_WORKSPACE, ES_BASE_URL, ES_DEBUG=1.
Credentials are stored per deployment, in the system keychain where there is one. The CLI’s sign-in is separate from an agent’s connection: connecting or disconnecting an agent leaves it alone, and signing out leaves the agent working.
eversince tools opens with the operating instructions for whichever it is talking to, the app or the cloud, so a script reads the same rules an MCP agent does.
