Get a specific access list by ID
AI agents call get_access_list to retrieve information from Nginx Proxy Manager MCP 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 an access list without modifying, deleting, or executing any operations. It is a simple query operation that returns data based on an identifier, characteristic of Read operations. The severity is low because access list information is typically configuration metadata with no critical security exposure if retrieved.
From the tool's definition Tool name 'get_access_list' and description 'Get a specific access list by ID' indicate a retrieval operation with no side effects.
