List workspace users. Requires Enterprise plan + Org API key.
AI agents call notion_list_all_users to retrieve information from MCP Notion Server (@suncreation) 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 workspace users without creating, modifying, deleting, or executing any operations. It has no side effects and presents minimal risk—the information retrieved (user lists) is typically available to workspace members. The requirement for Enterprise plan and Org API key provides access control but does not change the fundamental read-only nature of the operation.
From the tool's definition Tool name 'notion_list_all_users' and description 'List workspace users' indicate data retrieval with no modification or deletion. The description explicitly states it lists users, which is a query operation.
