AI agents call xhs_get_note_detail to retrieve information from XHS-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves note information by ID without modifying, deleting, or executing any actions. It is a read-only query operation with no side effects. The low severity reflects minimal risk from misuse—an AI agent could only access existing note details, with no ability to alter or delete data.
