Get users and groups assigned to a specific project with their roles. Supports pagination for projects with many members.
AI agents call get_project_memberships to retrieve information from Redmine MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves membership information (users, groups, roles) for a project. It performs no modifications, deletions, or side effects—purely a data query operation. The severity is low because membership lists are typically not sensitive organizational data, though confidence is high given the clear read-only nature of the operation.
From the tool's definition Tool name 'get_project_memberships' and description 'Get users and groups assigned to a specific project with their roles' indicate a retrieval operation.
