Delete an environment variable from a service
AI agents call delete_service_env to permanently remove resources in Coolify MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes environment variables, which cannot be undone without manual recreation. Environment variables often contain critical configuration, secrets, or application settings. Deleting them could break running services, expose application logic by forcing fallback behaviors, or disable security controls.
From the tool's definition Tool name 'delete_service_env' and description 'Delete an environment variable from a service' explicitly perform irreversible deletion of configuration data.
