Get members of an organization. Use this to see who belongs to a workspace.
AI agents call get_organization_members to retrieve information from Trello without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves organizational membership information without modifying, deleting, or executing any operations. It is a pure data query with no destructive or side-effect capabilities. The scope is limited to viewing workspace composition, presenting minimal risk even if invoked by an AI agent.
From the tool's definition Tool name 'get_organization_members' and description 'Get members of an organization' indicate data retrieval with no side effects. The verb 'Get' and the stated purpose 'to see who belongs to a workspace' confirm read-only querying.
