AI agents call get_members to retrieve information from Ghost MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves member data from the Ghost CMS without creating, modifying, or deleting any content. It is a straightforward read operation that returns existing data. The lack of parameters for filtering or modification, combined with the 'get_' prefix and list-retrieval semantics, confirms it is a Read-category tool with low severity.
From the tool's definition Tool name 'get_members' and description 'メンバー一覧を取得' (retrieve members list) indicate a retrieval operation with no side effects.
