List installed site adapters
AI agents call site_list to retrieve information from Ma Browser without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about installed site adapters without modifying, deleting, or executing operations. It is purely informational and has minimal blast radius—an AI agent misusing it would only gain visibility into available adapters, not access to sensitive data or ability to perform actions on external systems.
From the tool's definition Tool name 'site_list' combined with description 'List installed site adapters' indicates a query/retrieval operation with no side effects.
