Enable or disable auto-renewal for a paid option. When enabled, renews from user balance before expiration.
AI agents call paid_options_toggle_auto_renewal to retrieve information from StealthSurf MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
