List user memberships in a project.
AI agents call list_project_user_memberships to retrieve information from Infisical MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists existing membership data without creating, modifying, or deleting any information. It is a straightforward read operation with no side effects. Even if misused by an AI agent, it only exposes membership information visibility, which poses minimal security risk compared to tools that can modify or delete data on this server.
From the tool's definition Tool description explicitly states 'List user memberships in a project' - a query operation with no modification capability.
